C4 Vette Valve Cover Gasket Replacement Part I

When I advertised this project I blogged that I didn’t understand why GM, given how hot the 1984 C4 ran, would use cork as the material for the valve cover gasket and how I wouldn’t replace them with cork. So I called a popular Vette parts supply house and ordered Ultra-Seal.  I did check locally. ok fine, I checked one place, the Checker Auto down the street, where, through some extremely ineffective communication (the guy didn’t know what he was talking about or what they had in stock), the employee said, “All we have is cork.”;  to which I said, “No, thanks.”; to which he said, “I can order something else.” to which I said, “So can I.”   (There… that bit of typing is for you grammar-sensitive types.)

I also tossed a query on the forum for the Vette group I belong to, and a couple said they do still use cork, and a  couple highly suggested Fel-Pro.  Funny, they said they got them from Checkers.

Yesterday, I received the Ultra-seal (made by Mr. Gasket) I ordered from the Vette parts place. The Ultra-seal…was cork!!!!!! So much for the description on the web.  So I got on the phone to the Checkers down the street and I got an employee that actually knew what they had in stock.  They had every type: rubber, rubber with metal, liquid, metal, and cork.

So when I got there, I picked up the set of the Fel-Pro and Mr. Gasket’s rubber gaskets.  I hear my inner critic say “Hey, average car guy!!!  Yeah…I’m talkin to you, Mr. Average budget!!! What do ya think ya doin’?!!”

Here’s the deal.  I’ve never taken the valve covers off the Vette before, I’m not sure about the clearance, or the angle of the plane the valve cover sit..yadda..yadda.  Plus, I kept the receipt so I can return them…and I will!!!!  Promise!!!

So the Ultra-Seal looks like this:

CORK…BAD!!!!

Sorry about the pic ..didn’t open them because they have to go back.

The Mr. Gasket I purchased from Checkers was metal covered with thick rubber:

Mr.Gasket Rubber and Thick Metal

They are very similar in thickness and shape as the Ultra Seal.

The Fel-Pro are the ones I’m going to put on the car.  They are metal covered with thin rubber and the holes are re-enforced with metal washers and are grooved.

Fel_Pro grooved and will hold better during installation.

So that will be next up.

Next Project Corvette C4 Valve Cover Gaskets and Paint

So if UPS has its act together I should be getting a set of valve cover gasket and engine paint to repaint the Valve covers and installing them all on Saturday and part of Sunday if necessary.

I could have got the gaskets locally, but only in cork.  What I’ll never understand is the thought behind using cork in cars where the average engine coolant temperature is over 200 degrees.   Yeah..really.

The spec book on the 1984 C4 Crossfire engine has the thermostat requirement at 195 (degrees).  That means the engine has to reach nearly 200 degrees before the thermostat opens and allows the coolant to flow.  What more the Crossfire engine is came equiped with an electronic fan for the radiator and the is factory set to come on when the temp reaches 223 degrees. 

Now that’s pretty hot for an engine.  Rarely does my corvette digital temp gage find it’s self under 200 degree during while operating, it normally round 210.

So knowing that,  Chevy still put cork valve cover gaskets on the car.  If you’ve ever worked with those, you know that if the engine runs hot, they will eventually “cook” on and dry out and leak.  So I went with…. errrkk…. cut/paste “Ultra-Seal material provides a positive seal through controlled swelling of the gasket once exposed to hot engine oil. The polymers used in Ultra-20 also ensure gaskets will not harden and fall apart like others can. Gaskets are coated with an easy release material which helps prevent tearing when the valve covers are removed.”…end errrk and cut/paste.

The painting shouldn’t be a problem, it’s just to spruce them, but I’ll need to prepare them.  They are textured magnesium and can take a lot of heat but they do stain easily.  I’ll show close-ups of the before and after. 

Actually you can see some of it here.

errrkkk….Normally my engine isn’t this awful looking.  But it’s been a wetter than normal winter and I haven’t kept up with it like I should.  Plus I haven’t been too worried about, know that I had to do these gaskets and hopefully, soon, I’ll be putting on the newly designed Crossfire intake.

Hey..don’t forget the Project Car Contest $100 online gift car to an auto parts house.

70 Mustang Dash Gage Removal Bulb replaced 3/24/2010

Well after the bout of bad video uploads I decided to stick with photos for the rest of this project.

This blog entry (I like the sound of that…’blog entry’) I’ll show some pic of the area behind the dash and the removal of the gage panel and bulb replacement.

As I suspected and as to be expected, the dash and gages have been out of this car before.  No big deal, it 40 years!!!  Clearing you can tell that because the screws are not matching that hold the gages in.

Right side of the gage cluster had philips screw with washer.

After the dash pad was removed there were really only 2 screw left that held the panel/cluster in place – seen above and below.

The Left side was not a philips

After these were removed the gage panel/cluster (ok….I’m just going to call it a gage panel…if you like cluster…read as “cluster”).  The only thing holding it in were two connections to the wiring harness.  Those just clip together..sorry….I had those on video… and pull off easily.

Part of the wiring harness

As you can see other than just being dusty, all the wiring was in good shape.  I had expected some issue due to age, but nope..not a one. (That’s not a complaint…no way…I hate electrical work…..I had a bad experience 🙁             )

This pic is of the panel on the right side of the and there is a LOT of space behind there.  A cd changer should slide back there as well as adding a dvd player to the plastic panel.  No I don’t believe I would, actually add one…..hmmmm…..I guess if someone donated an item I might consider putting it in…..or not.

The right side panel...lots of empty space.

 

Look at that room...for a donated dvd player....:)

So I did blew that out to get rid of some of the dust and wiped it down with citrus cleaner.

As I removed the two screws from the panel I thought it would pull right out but nope..the cover for the steering column had to be removed first.  Simple enough.

Cover for the steering column

Then……( insert…dooms day music)…a piece fell out!!!!! See below

queue the dooms day music...the loose piece.

Ok..not really a big deal.  It was just a clip that held the to pieces of the  steering column cover together.  It screwed back in slide of the two ends.

Now I didn’t take the gage panel out of the car didn’t really need to since the wiring was all fine. I pulled it out enough to allow my had to go behind and pull out the bulbs.

The position of one bulb.

Here is what the bulb and socket look like, together and apart.

Bulb and Socket

Bulb removed from socket

They come out of the housing by a simple twist. The socket has two copper conductors (you can see them in the pic above…one on each side) that come into contact with the electrical ribbon and provide the power to the bulb.  Most of the bulbs were still functional, very dusty..but I replaced them all. 

Ok that’s about if this “blog entry”  (come on..you like it too!!!…say it with me “blog entry”….I CAN’T HEAR YOU!!!!….BLOG ENTRY!!)

I’ve actually placed it all back together today and I’ll post more tomorrow.  But you want to see it before that, I’m driving it to work tomorrow…it not that long of a drive to Tucson…come down…I’ll spring for lunch…..            🙂

Sorry for the technical issues with the videos. It seems that WordPress has issues with longer videos, so I’ll have to keep them a bit shorter.

These next links will take you to the videos, but you’ll have to click the back button to get back to the blog.

This first video is when my son and I discovered that there was an additional bracket under the lower trim pieces.

This next video is view of the partial removal.

http://s299.photobucket.com/albums/mm296/timsweet2200/?action=view&current=MVI_6876.flv

This last is the rest of the removal.  I tossed a little humor in there about feed my son Ryan only if we worked for the meal.  Not sure he thought that was too humorous..but I’m his Dad..he has to deal with me.  🙂

Again, sorry these take you out of the site, I will work on this for the next video uploads.

Follow the steps and you’ll be able to remove those rusted exhaust bolts and it makes using an easy out on broke bolts…um…well… easier!!!!

1.  Heat the bolt or stud with a torch errrkkk….”Yo…us averaged guys don’t have a torch set!!!!”  Yeah, I know…I use a regular propane torch from ACE Hardware.  ….errkkk  Double nut the studs.

2. Once it hot…doesn’t have to be glowing red, touch a candle to it, until there is wax penetrated between the threads.

3. Remove the bold or apply the easy out and you are home free.

If you have a tip, post it here in a comment.

Thanks for reading.

Muscle Car Peeves

Ok, I’ve been wanting to do this for a while.  I have a couple of muscle cars and cars that aren’t but get “dressed up” like muscle car peeves.

So here are three right off the bat.

1.  Don’t put Yanko strips on your 2003 Dodge Neon.  It doesn’t look right, and you aren’t fooling anyone.

2.  I have nothing against body kits added to a car.  I, personally, wouldn’t do it to the two I have, but I’ve seen some pretty nice jobs done on Corvettes, especially.  I’ve even seen a lot of imports that look good with body kits.  But here’s my peeve, don’t put them on the car if you aren’t going to paint them the right way.  Save up the cash and get it all done at once.  And one more note on body kits, why would you want to take your Honda Accord and make it look like a 1946 pickup truck?  (OK, I’ve never seen one, but you know what I mean).

3.  I recently saw a 1970-something Camaro, mounted on the frame of a raised Chevy pickup…almost monster truck size.  Why people…WHY???!!!

Okay, there are a couple of mine muscle car want-ta-be peeves.

Post up some of yours. Come on, I know you’ve got them!!!!!

Thanks for reading.

Average Guy – Increasing Skill Set Training Parts

By | | , , , , , , , , , , , , , , , , ,
1 Comment

Now, I keep saying I’m an average guy with an average skill set and frankly there’s no one I know that will argue the point.  That being the current situation, it doesn’t mean that I don’t try to pick up new skills, I do.     

So since I also have an average guy’s budget (selling cans back to the recycler for car parts…ok…just kidding there) I don’t have what I’d really like to have for “training purposes”.  If I did however, I have two of each car (in this case a 84 Vette with a Crossfire engine –has to be exact there and a second Mustang with a V8) and I’d experiment with parts cars until I get it right and then I’d work on its twin.  Of course that’s not affordable, so I next like to have a spare Crossfire engine to mess with and a Ford V8 do to the same.  Now that might be possible, budget wise (I know a couple of guys that will let me pick up a an old engine for free) but I have an average garage, with my cabinets and work bench, I can only get one car in there–nope no 3 bay garage for me.      

My garage with the Vette in it.

 

(Was I kidding???? NOPE!!!) Errrk…..And don’t think I haven’t approached the subject…but the misses doesn’t see the need to move to a larger house just so I can have a place in the garage to play.  So having two engines on stands won’t work out too well. So how do I get around this……I purchase a part to “study”.   Back in the day you’d have to go to the junk yard and pick your part and you can pretty much do that today as well.  There are drawbacks to that, though… here in a AZ during the summer time…taking the parts off the a hot car is a killer…not stolen…but a car that’s been sitting in the sun when it’s 110 degrees out.  Those metal part will be a bit warm…trust me.  But the Internet is a great thing and I’d like to take a minute and personally thank former Vice President Al Gore for inventing it…nicely done sir!!!  I’ve found most of my training parts online.  But don’t over look the local car clubs either, you can get help and I can assure there’s one or  two guys there that have or know a guy that knows a guy that has the part you are looking for.    

  When I first got my Mustang, it had a 1 barrel Weber carb, so I purchased  an old one online to take it apart and look it over.  Then I order the kit and rebuilt the usable one.  I’ve done the same thing for my C4.  I needed a rebuild of the fuel injector towers, so I went online and found a set for $20 plus shipping and took them apart and back together and used them as a model for when I did the real set.  Worked perfectly.    

 Here is my next piece:    

84 Vette Crossfire Intake Manifold

 

Which is seen here on the Vette:     

Corvette Crossfire Engine

 

The manifold is unique enough that I wanted to learn more about it before messing with it.  Now if you’ve been reading my blog since the beginning or are new and went back through my older posts, you’ll know about my psychological issue with breaking it myself. So the test part makes it even odds…ok..fine 40 – 60 that I won’t screw it up. (That’s a 60% chance that I’ll eventually have to take to someone and have it fixed when I’m done fixing it myself.)  Now I’ve mentioned that an up and coming mod will be to put on a newly designed manifold for the Vette, but I need to keep the original and will eventually rebuild it myself…or attempt too. Look this picture over and you’ll see why I love working on my C4:    

Hood up.

 

 Yeah..no fenders to lean over!!!!  It’s great.  Easy access to the engine. Just toss an old blanket (STOP..NOT THE ONE ON THE BED..NO NO..BAD….) over the wheel and you are home free.     

 Thanks for reading.  Always up for a comment or two.

Drag Racing for the Average Guy

By | | , , , , , , , , , , , , , , , , , ,

In a previous post I talked about  psychological hurdles that an average guy, with average skill, average tools and an average budget has to deal with when he owns a classic car (ok…doesn’t have to be a classic…just “loved”).  One of those was the fear of something breaking, either while you driving it or working on it.  Can I fix it? Do I have the right tool?  What if I can’t?  Do I know anyone that can?  For free?  Can I afford to get it fixed?  Even worse – long will I be deprived of driving it? 

These are my concerns–always. 

So with these worries..what in H….E. double L (does everyone get the H..E double L??) am I doing drag racing!?!?!?!   Where’s my head at?!??!?!?!! 

I hope you aren’t sitting there waiting for an answer!!!!   ‘Cause I don’t know.  I just do it. 

But dude….you are so average….especially  in the budget….heck..in all the areas listed above…oh and BTW….how about SWMBO (she who must be obeyed)…how’s that going to go…..”Hey honey guess what?  I was at the tree and the light turned green and I got a huge jump on the V.W. next to me and the darndest thing happend…little pieces of my u-joint flew everywhere.  Would you mind moving your car so the tow truck back into the driveway…thanks snookems!!!”….Um…sure…… good luck with that!!! 

So over the next few post, I’m going to give some average guy tips for handling a little test and tune drag racing. 

Next up…do I need different tires????? 

Thanks for reading.   

My Coupe taking of from the line. Before the new paint!!!
