(they were all convertibles!!!…just saying!!!)

 

Oh.. you’ll like this one.

10/2/1959 – Chevy introduces the Corvair.  Believe it or not I’ve seen some of the sale footage and they treated it like a jeep.  Chevy had drivers drive up  embankment, up and down streams with water over the tires.  This gave Ford a scare but it wasn’t until they could put together the Mustang did they really have an answer.

 

1959 Corviar.

My Brother-In-Law’s 1965 Monza…very nice car.

Chasing Down Leaks – My ’70 Mustang

One thing I really hate is a leaky car.  I don’t like it when stuff leaks inside the car and I don’t like it when stuff leaks out of the car. 

I have a friend that alway says…”Hey…old cars leak.  That’s just what they do.”   To this I normally just respond with “Yeah…I guess so.”  I say this because he has pride in his work he does on his cars and I’m not going to poke at him about it. 

What I want to say is “Bullstuff!!!!” Not this day in age, there all kinds of reproduction parts and hoses that can be molded and even entire businesses that make custom hoses.  If it’s a gasket that’s leaking you can make your own, there’s all kind of gasket material on the market. 

If you remember back a bunch of post ago, you may recall my power steering issue with my C4 Vette.  Oh…yes…my poor old vette (which now has a new home), leaking everywhere!!!!.  I hated that, but it was all fixable, right down to having a place in town customize a power steering hose ( it didn’t actually get that far, the oddly shaped hose turned out to not be the issue.). 

The reality is that chasing down a leak is sometimes difficult, almost always time-consuming and the likelihood that it will be expensive is high.  So, no old cars don’t have to leak.  

What old cars do do (that’s just as funny to type as it is to say) is vibrate.  My ’70 Mustang is mostly stock parts, with the exception of polyurethane motor mounts, and it will shake stuff loose, is it a pretty raw machine.  A good portion of leaks can be attributed to that alone. 

A few weeks ago, I notice a dime sized dot of oil in my driveway….errrkkk….no I’m not a neat freak, my drive has spots (been meaning to get it power washed), but with my older cars I like to keep an eye out for issues.  So I climbed under the car and looked around and it appeared that the leak might be from the oil plug it’s self.   So I grab my 5/8 ” open end wrench and gave it a bit of a crank.  Now you have to be careful, especially with the type of oil pan I have (aftermarket chrome)  as it can get out of shape if you over torque the drain plug and really leak. I wiped down the pan so I could tell later on if there might be another leak. 

Chrome Oil Pan and Plug

 

A few drives later I noticed another dime size drip. Only this time  it was a bit further back.  OF NOTE:  My driveway is sloped, and pretty good incline at that.  This causes a bit of a problem determining exactly where liquid might originate, that whole gravity thing, ya know.  This drip did seem a bit further back then the last. 

Again I check the oil pan and this time the oil pan gasket between the engine and the block. Nope no oil.  So I go topside and start checking the  valve covers.  And sure enough there, there appears to be a leak in the rear of the left value cover.  Not really a big deal, looks like it’ll just need new valve cover gasket, this 302 engine is wide open in the engine bay with lots of room (nothing like the 84 Vette was to get to). 

Lots of room in this engine bay to work.

 

Valve Cover, you can see the bit of oil grunge along the bottom.

 

 I then recalled that FelPro gaskets were used and I specifically chose the type used on drag cars, designed so that you can pop the valve covers over between heats to make adjustments.  This particular set of valve covers that I purchased when restoring the car came with bolts that tighten with an allen wrench. 

Screw with allen wrench (or hex wrench).

 

 Just in case: 

Allen Wrench/Hex Wrench

 

Hexagon end of allen wrench

 

So I thought…to myself (really….can you think to anyone else?) “I wonder if they are all tight?”  Sure enough they were all loose.  Hence the oil leak.   I tightened them all down, wiped down the engine where I could reach and drove it a couple of days. No leaks!!!  Now I make it a habit to check those every so often.  This is BTW a good tip if you drive your muscle or vintage car.  

Now the latest leak, I noticed a couple of days ago.  I check the liquid laying in my drive (only about the size of a quarter) and it was power steering fluid.  I’m thinking oh…NO..not again!!!  I didn’t even look under the car and went straight to the computer and did a quick search for new power steering parts for my 70 Mustang. What I found wasn’t horrible, as in, well no retirement for me, got to fix up this ‘stang, but bad enough price wise to see if it was repairable. 

So I crawled under the Mustang (or hunk of iron, as my wife calls it…or maybe she was calling me the hunk  :^ ) and took a look.  Yup, there was a leak but it appeared to be coming from the flared steel hose fitting going into the power steering unit. 

Steel hose and the leaky mess.

 

A couple turns with a 1/2″ open end wrench and again wiped down area.   I keep checking back to see if any new leaks appear. 

I can say… right now…. that my 70 Mustang doesn’t leak….I don’t think!!! 

So now I stand corrected, sort of.  Old car do leak, hey new cars leak!!  However, they don’t have to stay that way.  

Tips: 

1.  Check under your muscle or vintage car for any liquid (hey…it’s ok if is just water from you AC..usually) on a regular basis. 

2.  Get under the hood and after your ooo’ss and aaahhh’s at your magnificent creation, tight things up. ( I always ooo  and  aaahhh!!!) 

3. Get the car up in the air “”SAFELY”” and check the fittings you can’t see or reach from the top side. 

4. Chase down the leaks and clean the area to make checking for a continued leak easier.

Corvette Consternation Part 3 Fuel Foley

Let’s recap for a minute: 

1.  Rack and pinion failure 

2.  Power steering leak 

3. Electrical system failure 

As you know the electrical system failure was the alternator and it was replaced. 

A now the story continues…… 

I picked the car up and it started fine, even had power to flip the lights up (it could do that when I dropped it off) and I drive two miles home.  It ran just horrible. No power at all.  That was worrisome. 

Now the ’84 Vette has  a very simplistic computer that controls the fuel injectors and it does take a bit after a “power outage” for it to get the mixture correct.  This should happen after a couple of miles.  Well by the time I got home there was no change in the how utterly horrible it ran.  So I took it for another spin and still no change. 

So I disconnect the battery for a few minutes and then tried it again…still the Vette could barely keep idle and giving it gas made it shake and the idle dropped to 400, 500 rpm.  So I thought ..ok..I’ll drive it to work in the morning and see if the 10 + miles will straighten it. 

Next morning, a Volkswagen bus filled with 40 people could have passed me like I was up on blocks!!!! 

Ok…at this point I’m getting a little bit…P.O.’ed…(that’s short for…oh..you know what it’s short for!!)  I call up my guys and I explain my displeasure.  My take was that they should have test driven the car and that they have had the damn (that’s short for @#$@#%%!!!!!) thing enough to know that it wasn’t running right.  I expanded on my thoughts in person when I limped the car back there after work..which was not a great day…which might have contributed to my disposition.  Sorry Sean, but you ya know noting but love…its all good dude….Sean later told me I hurt the only “feeling” he had…I told him to get over it.  They had a new guy there and he was the one that test drove it after the electrical work. 

This was the start of a 3 day, all hands on deck, WTH…(that’s short for “What The Heck” >wink?<…I didn’t want to push the envelope with the “bad words”, because I would have had to add “put the kids to bed ..I’m about to use some adult verbiage”) is wrong with this car!!! 

I’m thinking it’s still electrical, computer was F ‘ed (short for “fried”) or there was a short somewhere.  I ended up at the garage a couple of nights after work poking around a bit – Tim Sisk the guy that runs the places is good about that.  

So here is what was happened. 

 It appears that the evap system that is supposed to take the fumes from the gas tank for emissions was filling up with fuel every now and then.  This system is supposed to push the fumes through a canister filled with charcoal and remove some of the harmful particles.  Of course it doesn’t stop there the “cleaner” fumes then are pass back into the intake manifold to be “re-burned” and sent out in the world through the Vettes exhaust system.  This simple hose highway runs along the entire length of the car and isn’t designed to handle fuel.  

The end result was fuel running through the hose design for only fumes, traveled the hose highway all the way to the front of  the car,  filling the charcoal canister – which wasn’t designed to hold gasoline.  Once full the gas has not where to go but across the engine, just following Avenue Hose, and dumping fuel directly in to the intake.  That’s the cause of the poor (understatement) idling and running. The car was drowning in fuel. 

Canister - now rendered useless.

 

How does this happen? Well it occurs when too much pressure builds up in the fuel tank.  The venting of the fumes is supposed to prevent that. Once the pressure builds, which doesn’t take long with a full fuel tank, the gas has to go somewhere, so it takes a trip up the evap hose. 

Now, here is where a guy starts to wonder  WTH (short for….) am I doing with a one off car???!!!  Really the 84 Vette is a one off production year.  There were not ’83 Corvettes sold and although it has the same basic engine as the ’82 Covertte crossfires, nothing else was the same, and the ’85 Vette was an entirely different animal.  This leads to a fairly significant lack of printed knowledge on the system..this many years out.  Why do I mention this?  Because it’s tough to find the knowledge after this long and the newer repair books treat the ’84 systems as ..”oh yeah..it’s not the same as the ’85 or the “L83 (my engine) is similar.”  Gee..thanks for that.  But it is different and it’s not similar in many ways. 

Here is one.  

The fuel tank on ’85 Vette has what is called a check valve with allows vapor to travel through it, but if fluid enters it, a small ball is pushed by the denser liquid to a point where it will block the hole.  There is a diagram of that in many of the new  repair books.  But there are none for the ’84, and no, upon actually view the parts, you aren’t going to see anything that looks like the ’85 check valve. 

Ok..armed with is knowledge, I showed up at the garage and share the info.  This left us all scratching our heads.  There seemed not logical reason for pressure to build up. There is only the fuel pump down there (that we tested in a bucket of fuel and worked as it should)  there was only one other fuel delivery system was the “limp home” system which use the oil sending unit to push just enough, when the tank was low or fuel pump failed, to get you home or a repair shop. 

This lead into the third day, at which point the fuel module was removed from the tank again and it was discovered that there was indeed a check valve. 

There is a check valve built-in to the fuel module, it had a piece something (appeared to be plastic or maybe rubber) lodged in it large enough to keep the ball in a position where the it increased the pressure so much that sent it shooting fuel out up the vacuum line.  It was incorporated into the system in a way that was not conducive to separate replacement.  It was cleaned and that solved the problem..well most of it. 

The canister should be replaced find one it not easy. Right now we replaced the PVC valve with a right-angled and the canister is no longer in the flow. 

For my 84 that’s not a problem since there is no sensor that checks that and the car is running great. I’m not sure but I think she’d even pass emission, unless they were to visually see that it wasn’t connected. 

Of course I’m a big tree hugger and (you can tell because the Mustang gets 4 gallons to the mile ..hey that’s what dead dinosaurs are for!!!!) so I’ll eventual get it replaced. If I can find one.  In the mean time I’ve re-routed the  hose to protrude under neigth the engine so the fumes don’t fill the engine bay. 

Some pics: 

Hose Highway with Canister

 

End of the hose that is supposed to travel on to the Intake, now routed under the car, temporarily.

 

So there you have.  Good thing there wasn’t a car crusher in towing distance….nah…I love that car.

Corvette Consternation Part 2 Electrical

So I bring the Vette home and the steering feels pretty good and although my 70 Mustang has power steering (I had been driving that all week..yeah..I know..”poor baby!!!”) there really is no comparison between the two.  I get home and park it for the night.

Next morning I’m up early going to wash both cars, so jump behind the wheel of the Vette to pull it forward a bit and…..nothing!!!   No power, nor lights, no key in the ignition buzzer, nothing.  Hey, there wasn’t even a clicking noise when turning the key.   I’m think great..what could I have left on that would kill the battery that badly.  Answer was nothing.

Now if you’ve some of my earlier entires, you’ll recall that electricity and I mix like, um….like..um…Amps and water!!!!   As long as it stays in the wire and gets from switch to device and nowhere else, I’m good.  Have that perfect universe interrupted and I’m not hanging with that.  I hate electrical work.  I hate thinking about, hearing about it and living through it.  And this isn’t limited to car, but that’s my topic here.

So I get out and raise the hood, but for I get to far I see a huge spot of fluid laying under the car.  Right about now I’m starting to get that…”all old cars should be crushed” thought running through my head and then..”I’m gonna find the guy that did that work, right now, on a Sunday and drag his happy but out of church (if such a demon would be allowed in one) and rub his noise in my…yeah…you guessed it….power steering fluid!!!    (Breath…breath..that was two weeks ago….come one now..simmer dow…………..HEY IT STILL FEELS LIKE YESTERDAY!!!!   Ok….ok…better now, it’s over and it turned out….OH>>>WHOA….don’t tell them now they won’t read the next two posts and your rating will drop below 2 reads a day!!!…Yes…Yes must get a grip!!!!)

So I started up the Mustang (they sit side by side together in the driveway nose to butt – have to back the Vette in or it won’t clear the end of the driveway) and maneuvered it over to the Vette so I can jump it with jumper cables.  I have a fairly new jump box but it never really seemed to work, and then I lost the power adapter ( stupid electricity) and it just sits in my garage.  I hook the cars together with jumper cables and allow the Mustang to run on high idle.  Get in the Vette and …nothing… not even single dash light.  The charging when on for some time before I could get the Vette to turnover and she started up, but she wasn’t happy.  I took the cables off and then for some unexplained reason I turn the vette off.

Crap!!!  So I turned the key, but I already knew how that would because there was still no key in the ignition buzzer..nope….and no click of the starter solinoid…and that would be a triple “Crap”!!!!  It took just as long to get her started again only this time I wasn’t going to turn it off.  I drove it over to the guys that put in the rack and pinion steering (of course it’s Sunday and I call and let some one know I was leaving it and to put it inside.  At this point I wasn’t happy, the power steering leak on a new system and now an electrical issue!!!!

Next day was a Monday and I called up  my friend Tim and said, “Hey..uncool to find fluid leaking and my electrical system is  f ‘ ed (short for fried….yeah right).

In the end it was just a hose that didn’t get tightened, oh and my alternator was in fact f ‘ed (short for fried).  The alternator came that afternoon and the car was ready the next day.  And that is that…end of ……………..yeah…nope…..I wish!!!!!

If you can guess what’s next, I’ll send you a DVD.

OH..here is the new rack and pinion all clean and nice looking!!!

New Rack and Pinion This was taken today 8/31/2010

Thanks for reading and yes Steve Sears..you have to wait  for tomorrow for the rest.

Corvette Consternation Part 1 Steering

Every one that reads this blog knows that older cars, no matter how careful you, or how much you baby your car you are going to have problems.  That’s the nature of any relationship.  Things break, undiscovered issues, or even your own missteps can issues.  You just can’t through in the towel “Honey, I’m going to have to find another mate, you just can’t run as far as you use too.” or “Sorry but that broken leg changes everthing…ur outta hereeee.”  (Lawyer up…my wife is fine, no injuries, still running fine..no worries…just wanted to be clear!!!!)

Well, over the past few weeks my Corvette has been a serving up a bunch of consternation.

If you remember a few posts back I had replaced one power steering hose and need help with the power steering reservoir.  That got done.  Shortly after that, a leak developed from the front end and over the course of two days it got a little worse.  So I pulled it in to the garage and crawled under neight..and that’s no small effort. 

The power steer of course provided hydraulic power to make the turning of the front wheels easier. (There you got the basics of the how it works.)  This entire process insists that the fluid, in this case power steering fluid stays in place.  Well my beauty failed conform to the standards. 

Rack Pinion

If you look at the image above you’ll see the plastic boots (A) that cover and protect the shaft.  Those are supposed to be dry.  When I touched the boot on the left side of the Vette fluid poured out, clearly it was no longer dry.   What was also very very clear at that exact moment was the pain in my wallet. 

Basically, the you have two options when something that is supposed to be dry is wet on a car, replace it or rebuild it.  I chose both.  Lucky for me the complete unit for my 84 Vette is still available through on-line Corvette parts houses.  EEERRRRKKKK..While I’m writing this I have the Speed channel up on up in the corner of my monitor, they are testing an Aston Martin DBS against a  Bentley w/ W12 engine…soft girl cars…of course that girl’s got some skills, putting eyeliner on at 150 miles per hour!!….end of EERRRKKK – I’ll let you know how that turns out.

A quick trip down the street to Tim Sisk proved my investigative results.   I’m the Average guy with Average skills, there was not something I wanted to attempt. Additionally, it requires a front end alignment.  So I order one, and because I hate having the car in the shop I had it expressed shipped, or at least that’s what I asked.  It didn’t shipped and took a total of four days.  What…you say…”oooohhh poor baby, took 4 days to get it here!”    Hey, that’s a life time for some car guys!!!!

Now ordering the rack and pinion requires a core charge (that’s where you have to return the old part or pay the core fee – they rebuild the old part and resell it) but as I stated I wanted to do both so I paid the core fee and kept the part.  This allows me to either learn to rebuild the part or sent it out to have it rebuild and store it way.  Plus I have the original part, although there isn’t much benefit in collector value for having the orignal rack and pinion (numbers matching) 84 Vette, well least not for another 20 years!!!!

The part was replaced and the car realigned, in total it was out of service for a solid 7 days. Picked the car up and drove it home and that was that…and if you believe that, I have some swamp land out here in AZ to sell ya!!!    Stay tune for what happened next

Oh…the Aston Martin and Bentley match up.  Here the details:

Braking 0-100 to 0 (time speeding getting up to 100 and then distance measured for stopping-shortest distance wind) ….15 second from 0 to 100 for both cars, breaking the Aston won at 40 feet shorter stopping distance.

60-130 test on roll – Bentley win 13.2 second, nearly a second faster than the Aston

The rolling mile  – top speed 165 mph for Bentley, 1 second faster than the Aston – 159 mph

Road course – 55.6 seconds for the Bentley      53.8 seconds for the Aston

Like I said – girls car..my 84 Vette has a top speed of nearly 200 miles an hour.  My personal best, 174 mile per hour in the Vette – yeah that’s just last year.  Dyno proven.

Vette troubles Overheading Do’s and Don’ts Part III

The news is all good.

WOT (decided to give her a name) is back in the driveway.  Compression and heads all checked out.  3 cheers for American  Iron!!!!

(OK..WOT is funny because it’s a crossfire with least HP in the C4 Generation.)

Took it for a spin after picking it up and everything seems to be fine.

New hoses, new thermostat, new coolant..yeah…all of the old stuff is back in town, new transmission fluid (maybe over kill but there is the a school of thought that a major overheating event can cause a failure…safe..not sorry) and oil change (I’m not sure what happens to engine oil at 300 degrees – but safe…not sorry).

Vette troubles Overheading Do’s and Don’ts Part I

The other day (7/1) was a record-setting day for me.  Oh..yea..setting some personal bests, that….well….frankly I could have done without!!!!    

 So I thought I’d take a minute or two to jot down the events of the day, as a form of therapy, and maybe I won’t feel like having all my cars crushed and moving to a small Quaker community in PA.   

Ok…. that does feel better.  Now say it with me…”I’m OK and You are OK”.   

So here’s the story and I’m being as dramatic as necessary!!!!   

Drove my 84 C4 to work as normal yesterday………   

>>>Oh..hey wait…..I did this Corvette owner thing a few weeks back…guess what it was?…..{silence….cricket…cricket….cricket..}  Give up?  Ok..fine I’ll just tell you.   I got a personalized license plate…No..not a vanity plate that says “Studly” like my wife wanted me to get!!!  {{If you only knew how funny that last statement was..my wife hates those plates, although I believe he thinks I am studly!!!}}. Nope I had to get clever,  I wanted something that defined my car.  You have no idea how many times I get asked…”Yo…what years is it?”  My neighbor next store ask me that every time he see me outside my house…he’s 80 something…so I’m very polite about it (’cause I’ll be 80 some day), and tell him it’s a 1984, and always ask him if he wants to take it for a spin and we both laugh.  (Man..you’re getting your money’s worth reading this one..three stories in one.) Any way I thought if I could squeeze the year of my Corvette into the plate and I wouldn’t have to answer it as much.  ( I actually got a stamped “1970” plate at a place in a shopping mall for the front of my Mustang for the same reason…Arizona only requires a rear plate…funny..they still sent out two plates though!!!)  (Geezzzeee..there’s 4 stories for ya…I don’t think I remember what the orignal was??!?!?!).  The plate reads  “84C4WOT”.  Deciphered it means   1984 C4 (the generation) and WOT = Wide Open Throttle.   

Wow was that painful to read through?  Hope not!!!   

Ok, back to the original post.  Got to work just fine no problems.  Now, this time of year it’s get’s pretty hot here is Southern AZ and  I think yesterday was about 105 or 107.  My work day went by as slow as it possibly could and I had to hang a little late to finish up a task.  I head home and I got about  4 miles from work and I noticed the cars behind me slow down and to a little swerve in the road.  If you’ve driven here in Tucson much, such things are not extraordinary, there’s a lot of weirdness here on the roads.    

Approximately 1000 yards down the road I see my digital temp gauge, jump to 260 degrees.  Now the 1984 C4 runs hot by factory standards.  The electric fan has a factory setting of 223 degree before it kicks on…but 260…is not good…not by any stretch.  And picture my expression on my face when 200 feet further it shot to 280 degrees.  I’m doing about 45 and I’m in the middle lane of a 3 lane street and traffic is heavy.  I know I need to pull this thing over or that which is currently going very bad..is going to get even worse.  I cut off the next car where there was the smallest of a gap and dove for a  Circle K (like a 7-11) parkinglot about another 500 yards away.  As I pulled in to the parkinglot…my temp gauge read  299 degrees (my first new record of the day..beating the old temp by a whopping 17 degrees…”Tell him what he’s won Johnny!!” ” Well Wink, he’s won a cooked corvette and gas saving trip on the back of a tow truck!!!!”.) DOOM!!! was the only word that came to mind….ok..fine…that wasn’t the word…but it did have 4 letters.   

I stopped it, turned it off, popped the hood latch and jumped out of the car to get the front lifted up….  I expected to see coolant gushing out of every place imaginable, but the engine compartment was pretty dry…I’m thinking..this is not good…nope….not good at all.  There was a little fluid on the frame and a small wisp of steam, but nothing to make you think there was an Old Faithful event about to occur.  I checked the coolant overflow tank and it had a small amount of fluid in it..very small, odd for something that was about to blow.  I quickly checked the hoses that I could see, without touching anything….every thing was hot, and they looked fine. I could even see a portion of bottom hose, it seemed ok.  I stepped back and looked under the car and there was only a very small puddle.  Corvettes are pretty low to the ground which makes it hard to see anything will out getting down on the ground, but I had on white paints and when it is 107 degrees in Tucson, the pavement is about 115!!!   

So what my observations imply is there wasn’t enough coolant in the car to boil…and at about 300 degree…it would be boiling!!!   

 There are only a couple of things that would a cause a complete drain of the cooling system.    

1. A hose coming off.  Since there wasn’t any coolant on the upper part of the engine, so the top ones were fine and what I could see of the bottom hose it seemed normal.   

2.  A cracked block or a head would have had the Vette running poorly before hand and I would have noticed.   

3. Freeze out plug failing.  I’m thinking this was the problem.  A freeze out plug is just that, a metal plug in the block and heads of your engine. They are there mainly for cold weather climates.  If the coolant was mixed wrong with too much water and should this mixture freeze,  the plugs will pop out during a “freezing event” allowing expansion of  liquid hopefully saving the engine’s metal from cracking from the pressure.

Freeze Out Plug in the engine block.

 

Why is that so bad?  They look pretty simple to put back in.  Sure they are, right…after you pull the entire engine out!!!   

So there I stand, white paints looking soiled, red Vette with hood up and smelling like a burnt carrot, 107 degree, humid as hell, and it starts to rain.  Can you picture it?    

I made a quick call to my GM Motor Club and they arraigned for a flat-bed.   2 hours later my lovely wife meets me at the Circle K and we wait together for another  45 minutes(total of 2.75 hours) for a truck to show up (my second record of the day… breaking my last tow truck wait by 1.25 hours) and 45 minutes after that I waiting in my favorite repair facility parkinglot waiting for my poor Vette to be dropped off (where it would sit, in the dark, overnight, all alone and wounded).  Too much drama?   

Let’s get to the do’s and don’ts.   

1.  Do pull over in  a safe spot as soon as possible.   

2. Don’t continue driving. Don’t try to make it home or one more block/mile.  You could just be making it worse.   

3.  Don’t keeping it running after you stop in a safe place. It isn’t normally going to cool it down and again you could be making it worse.   

4. Don’t touch anything under the hood. Don’t open the radiator.  Don’t open the coolant overflow reservoir.   

5.   Don’t try filling it with water or coolant immediately.  Just let the car cool down all the way down.   

6.  Don’t try driving it after its cooled down, even if you filled it with water.  100% chance that what caused the overheating, didn’t go way.  

7.  Do call a tow truck.   

8. Do call a friend or someone and let them know where you are, at the least.   

9. Do get a motor club of some kind.  Average Guy with average budget..right? Towing is expensive, very expensive.   I like the GM Motor Club.  I pay about $69 a year and I’ve used it twice this year already.  I have my son’s car covered and my Corvette. (The Mustang is covered by Haggerty insurance.)  Within town the towing is free up to a certain mileage, both this years tows were free, saving about 250 bucks a shot, that a good deal.   

More coming up.
