Question from Reader Dodge/Plymouth 318 Poly

Steve asked. 

As long as you are on the subject what the heck is the difference between a regular 318 and a poly 318? 

Poly is short for Polyspherical head. Some say it was a forerunner to the Hemi (Hemispherical head). Basically it was based on a theory that you could get more combustion or volume by angling the intake and exhaust valves then if you had them parallel. From Hemmings  Motor News book of Chrysler Performance Cars…”The ploy’s exhaust valve is located parallel to, but offset from, the cylinder axis.”  

This increased the efficiency.  The hemi was constructed to increase the efficiency with a more angled system. The shape that the valves make are semi-circular with the Poly being a little flatter than the Hemi.  I did the below image in Paint.

Thanks for the question Steve!!!  More to come on the 318.

84 Corvette – Power Steering Work II

As I stated in my last post, the molded hose for the power steering unit is no longer made.  So here is an idea that can be used to get around that problem for really just about any regular hose for just about any use. As long as the diameter is correct you can you use metal pipe for the molded portion of the hose.  My plan was to remove the shaped hose and take it to a shop that specialize in shaping pipe or least as a sideline to their metal work business.  They can normally create any shape.  After that is shaped, you can use straight hose on each end to attach to the fittings.  You’ll need two additional hose clamps. This is made easier if you have the metal shop slightly grind down the ends to slide into the rubber hose ends.

 Pls note that you have to be sure that metal is proper for the area you are going to use it in and for the fluid that is going to pass through it.

 So that was my plan for replacing the discontinued hose.  I typed “was” because as I got into the project I realised that particular hose was not necessary to replace.  This was a stroke of luck, because it would have taken a few days with the Corvette apart to get that accomplished.

 I’m going to give you a heads up right now.  I did NOT finish this project just on my own.  Nope, that whole Average skills and Average tools thing plays an important role in accomplishing projects.

 I took a couple of videos and I’ll see if I can get WordPress to work better than last time and I’ll toss them in at the end of this entry.

HELPFUL HINT:  There is a lot of fluid in the power steering reservoir.  As soon as you release the hoses, it’s going to poor all over the front of your engine and then on the ground.  An oil change tub will help keep it off the garage floor, no staining and no tracking it around. However, it will still run down the  engine.  So, I used a turkey baster.  EEEERRRKKK…(yeah it’s in caps!!!)  Do not put it back in the kitchen when you’re….NO…NO..NO….In fact if you are smart, ask first!!!  I did and I was surprised to hear  “Sure, but you’ll have to purchase a replacement.” For a minute I thought….well that’ll come out of my car budget….and I thought…I wonder if I can clean it up…and…ummm…(kidding of course).  It worked great and I just have to purchase one…but not until Thanksgiving!!!!  $10 bucks says..I’ll forget and have to run out on Thanksgiving and stand in line for 1.25 hours, if I can find one at all.  BTW – I recommend “Pampered Chief” brand for power steering fluid removal!!!! The next couple of pics show where we are on the engine and the hoses.

The two circles indicate the two bolts that need to be, “at the least loosened” if not removed.  You’ll notice that one can not be removed, unless the pulley is removed. I’m not going to take the pulley off and there lies the issue that I needed assistance with. 

But I did manage to remove and check both hoses, which resulted in the determination that the discontinued molded hose was still in great shape and not a threat to leak any time soon. 

Another look at where we are

A good look at the hoses. Most of the mess is not from the hose, but the cracked reservoir.

 

Here is at the end of the bulk hose that goes from the reservoir to the power steering pump.

Old hose 2

 

It was in pretty bad shape. 

PS pump and the mess!!!!

 

And here is the pic with the new hose attached. The hose had to be routed back through the reservoir bracket.

Hose lower connection.

 

As it turned out the actual removal of the reservoir required the removal of some key bolts that did in fact impact the position of the alternator.  As I removed the bolts I noticed the alternator shift.  At the beginning I didn’t think that was possible, because there is a solid bar attached to the alternator and the engine, however it did not.  I had most of the bolt out and decided that I’d better get them back in and I did except one and I should not get that one to line up.  

So off I go to my favorite place down the street and I had them finish it up. 

Here are some after pics.

New reservoir.

Another repair down.  It’s been a couple of tough months for the Corvette and her engine is going to need a good detailing, but not just yet.  I have another huge modification come up…a new intake.  That will be pretty soon, so keep checking back.

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).

Hanging in Chi-town

Coming to you live from The Witt in downtown Chicago, it’s me typing on my laptop.   Three more days to enjoy relaxing and seeing the sights.

Speaking of sights..what I don’t see is a lot of muscle cars now or old…errrk… let me explain “lot” in this context it means…. “almost none”.  I’ve actual only seen one newish corvette (C6 – convertible) and a 1968 Mustang.  The Vette was on the street and the Mustang was parked in an alley.  That’s it!!!.

Muscle Car Drought..the only Vette I've seen!!

Ok…hang on,  if you think I just sit and type uninterrupted..nope…not much chance of that.

 My better half is here in the Windy City, at an international interior design event, where she’ll be giving a talk on….um…some interior design subject….um….yeah…I pretty sure that’s right and I tagged along. Nice little vacation where I can tool around a big city, which I enjoy doing from time to time.  What’s my point…umm…oh yeah….so I just ran out to get pick her up a couple of items while she is practicing her presentation.   On my return trip back to our hotel I spied  a beautiful custom 2010 Mustang..so..that makes three!!!

 Would you drive  your vintage or newish muscle car around a large city?  Let me say that I’ve been walking and taking cabs and even ridding on top of the double-decker tour bus and I’ve seen how these Windy City dwellers drive….I’d have to day…..I don’t think I would.  These folks drive 50 miles an hour between stop lights…but..still I might consider it early on a Sunday morning!!!

Oh…bTW…I know these guys!!!

My Parts Guy.

Oh and in the category of hanging 1930 Chevy’s….here ya go…a 4 door sedan at Portillo’s.

Steve Sears 1992 Ford Ranger XLT and Paint

Steve Sears is one of the readers of this blog and owner of a 1982 Mercury Cougar Station Wagon (again..I love this car). 

But that’s not all, Steve does a lot of his own work, including this unique paint job on his 1992 Ranger. 

Here is his recent project. 

The before: 

1992 Ford Ranger XLT

 

Tim, 

  

I completed my project last week and thought you’d like to see it.  I painted my Ranger with a roller.  I only did six coats of each color, usually 8 – 10 coats are required.  I like to call the color Haze gray underway and white.  I spent 26 years in the Navy so I thought the gray was appropriate for me. Ha Ha.  It’s painted with rustoleum mixed with mineral spirits in a 1:1 ratio thus the many coats required.  The body prep is the same as any other type paint job except that a primer is not used over the whole truck.  I only spot primed the bare metal and over the bondo used to fix parking lot dings.  It took a full 8 days to complete the project including the paint on the topper.  I have to wait a few weeks before buffing out for a full gloss.  For that I’ll just remove the mirrors and the bug shield on the front.  The process is well documented on the web over the last 10 years or so so I won’t repeat the process.   

  

I thought your readers would be interested. Finally I have the truck looking like new again.  It’s a 1992 Ranger XLT that I had bought new on April 24, 1992.  It has the 2.3 liter four and a five speed tranny.  The picture labeled 019.JPG is the before shot is attached.  

And the after photos:

Thanks very much for sharing it Steve.  (A roller?  Wow!!!!)

Mustang Hose Woes

I was about to start the pillar moldings mini project when I ran into a couple mechanical issues.

About a week ago the Mustang began squealing when pushed to high revs.  That normally indicates one of several problems.

1. It could be a water pump

2.  It could be the power steering pump

3.  It could be a pulley

4. It could be a bolt that was holding the alternator bracket to the engine worked itself out and was in contact with the fan belt.

5. It could be a combination of the any of these.

Now the Mustang did, every once in a while, drip some fluid from the power steering control value but it wasn’t a huge deal.

Well, Saturday I went to start her and the battery was dead.  It’s over 3 years old and I had left the lights on the day before and had to have it jump started.  So off to the auto parts store I went and pick up a new 3 year battery and stuck it. When I started the engine up, it made the squeal and I decided I needed to fix this, before the pillar molding.

So with a neighbor revving the engine I noticed the bolt protruding from the water pump/block ( it passes through left side water pump housing in to the block).  With the revs the fan belt would flex and briefly hit the bolt.   This bolt was “custom” made when we were fitting everything up to reman’ed long block and was about 7 or 8 inches long.

It took a bit to get that back in place, had to loosen up the alternator’s other two supports and toss a little loctite on the threads and she was good to go…..almost…..

Yeah….option #5 above was the correct answer BTW.

Started it up and there was still a squeal – not the same squeal but clearly an ‘accompaning’ squeal.  Shortly after that a power steering hose let go and well liquid does what gravity  make it do and I spent the afternoon cleaning the driveway.  So there went my allotted time for Saturday.   So replacing both hoses seem the best way to go and they’ll  be in today.  Right now it’s at the shop down the street, I had no time to undertake this task at the moment, will be traveling the next couple weeks.

One of my travels takes me to the National Corvette Museum.  I’ll spend an entire day there which include the assembly plant tour.

Thanks for reading.

V8 Reference Book

I grab every book I think is useful in any of my hobbies.  I happened to be at the mall the other day and had some time kill and wonder down to Borders books store.  Pick up a book entitled “Ultimate American V-8 Engine Data Book” 2 Edition  by Peter Sessler, published MotorBooks.

This book has engine identification codes, component casting codes, internal dimensions and specs, and power and torque ratings.

It goes back as far as 1952 and covers Fords, GM, Mopar, and AMC, Packard and Studebaker.  It includes big blocks and small blocks.  There is a lot of information.

I learned from this book that all of the engines possible for the Corvette in 1984 were rated @ 205 hp.  The CFI was the main power supplier, but it also had listed a couple TPI’s (engine suffix code ZFC), TBI (engine suffix code ZFJ – supposedly for export only) and a 4v for California (engine suffix code ZFF).

They also inform you of the transmissions that go with the engines.

There are listings for cylinder heads parts or casting # as well as intake and exhaust manifolds as well.

I think this one is worth the  $30.00.

This is a great transition to introduce an up and coming feature for this blog.

I love engines…(duh).  To me the history of development, what was used when and where and maybe even why can be fascinating.  I’ll be tossing out specs and the like and hopefully some, ” I would have never guessed that” information.  Now, I don’t have this all in my head, it will be researched stuff or some experiences. (My 1974 Torino was a good case study..tell you the story soon).

Thanks for reading.

SCCA Event 4/25/2010 Auto Cross Part I

The name of my blog includes “racing”.  This isn’t meant to be watching on TV and reporting back, it’s meant to be my events.  My blog title also includes  “Average” and includes budget as well.  (You might as well include ‘time’, as in average amount of time to spend on the hobby.) 

I just finished running a Sports Car Club of America (SCCA) event.  It was a blast!!  I’ll get to my times in a bit, but first, let’s talk about cost of this particular event. 

Straight up to join SCCA there is the yearly fee for the national membership and there is the fee for your regional membership. Total cost here was $80.00.   Now the events are not free.  In my regional club which run events in the Tucson areas and Phoenix as well, they have to offerings.  They have a round for points and time and they have the time only round.  There are separate prices for each. 

Today when I showed up (you can pre register and save ..I think…$10.00) filled out all the paper work and went to pay.  The fellow taking the money asked if I wanted “time only” and  I’m thinking…do I only want to be timed…so I said “No.” and he said “That will be $30.00.”  So I paid. 

Now I have co-worker who talked me into joining SCCA and he attends regular events at the local drag strip – the auto cross is held in the huge drag pit/parking area.   He cleared up my misunderstanding and said if I wanted the “full” experience I need to go back and say yes I wanted the ‘time-only’ round as well.  That cost me another $10.00. 

So putting this together we are at 120 big ones this month to race.  Not too bad, I’d have to say. 

There are more costs and I’ll get to that in next portion of this subject.

C4 Vette Valve Cover Gasket Replacement Part VI

Ok..let me finish up blogging to you on this  event.  I had a read ask if it has really taken this long and the answer is No and Yes.  (I’ll explain the YES in a bit..it ain’t pretty!!!!)       

After find the correct bolts, wrestling the covers back into place was, I bolted them down.  Installed they looked pretty good.       

Check it out.       

Left side painted and installed. Still missing the emblem..right now

 

The only difficulty was aligning the holes in the cover and the gasket and the engine. Due to the lack of room to maneuver I wasn’t able to keep the gasket and cover holes aligned while wrestling them into place. I used two (small enough to slide into the threaded holes without damaging) phillips head screw driver to help keep them aligned and put the bolts in.       

Errrkk……whatever you do tighten them carefully…..let me spell that for you  (Mickey Mouse Club tune playing in my head)  C…A….R.(because you care about your car)…E…F….U…L…L…(cause you want to keep the oil full)…..Y…(because if you tighten too much on the 1984 C4 magnesium valve covers you’ll crack them and they can’t be welded, JB or other wise, and then you’ve got to find used ones, because aftermarket aren’t all that great)….Ok…end of Mickey Mouse Club song…and the end of one of the original valve covers….       

And in case you didn’t get the between the lines intention of the above Errrkkkk…I broken one.       

I wasn’t sure at first, my mind refused to process the sound so that I could be sure..it might have been a crack, or maybe I just crunched one of the plastic tubes covering a bundle of wires.  Yeah..that’s it…I sure (it might have been a crack though….crap!!…let me spell that for you…oh…never mind….just invision huge font type all in upper case, bolded and underlined.)       

I inspected the cover while it was in  place and I couldn’t see anything and said…ok.average guy.. with average skills and average budget..you have above average luck…at least today…at least that’s what I thought…or hoped.       

When that  happens the only way to tell is to either take the cover back off and inspected…that wasn’t going to happen…or let her run and build up the oil pressure and see what happens….that is what you’d normally do any way after replace the gaskets.       

Here she is running:  (includes bonus views of the injectors…I think they are pretty cool to watch.)

Covers don’t look to bad…but they aren’t going to stay…because..there really was a crack…but it didn’t show up  by leaking on this run…it should up the next day when I took the car to work.  I checked it when I arrived (about a 15 minute drive) no leaking…drove it home and she started to run poorly and had no power…yeah….it was leaking…on to a spark splug….got home and a little puddle of oil formed under the car and…well lets just say as I replaced the tightening episode in my head the crunching noise…sounded a lot more like a crack..in fact it was very clear on the replay!!!! The little referee in my head….said ‘After reviewing the play..the ruling in the garage is over turned, and Tim is charged a time out and $400.00 fine for cracking the cover and the vette gets parked until the parts get here!’       

Here is the pick where the crack occurred.       

Yup...cracked!!!!

 

That was Monday (4/5/2010) fast forward to today new cover have arrived (chrome) and they’ll be installed today or tomorrow.  So Yes it was finished and now No it’s not.       

Thanks for reading.
