Closure for all the blog readers.
Finished this up today. Here are some pics. (Yeah..I know..forgot to take them before I put the air cleaner on…but you get the idea.)
Only issue..the thickness of the chrome covers was less than the originals and I had to get a shorter set of chrome bolts. I have got quite a collection for chrome bolts now!!
THE END.
I’m now at the point where I can re-install the valve covers. I’ve painted them and cleaned up the gromets (for one of my vette buddies who was dismayed when the saw the interim pics).
If you remember I had to remove a few things including vacuum hoses, spark plug wires, a/c parts. In addition the bolts that hold the covers down had spark plug wire holders and other brackets for hold wires.
Brackets that would mount through with the bolt for the covers passing through.
Keep this in mind as I explain what I learned from my decision to use Fel-Pro gaskets.
Ok..fine enough dramma..lets get to the lesson I learned (which is often learned the hard way when you have average skills and less than average experience).
I am not smarter than the engineers at GM. They knew what they were doing when the used permatex…it was all about the bolts. Specifically, the length the engineers decided do use, or maybe it was the budget guys. They knew how to follow the build sheet. Here is the bottom line. The length of the bolts supported the thin layer of the permatex and the brackets shown above and that was it.
They did not support the thickness of the gaskets. They were just under a 1/4 too short. With the brackets and the Fel-Pro gasket in place barely two threads poke out, not enough to catch the thread on the engine. errrk….When did I know this and what got into your head to do it anyway?
Fare enough question. I found out when I queried a couple of Corvette forums about what gaskets to use. I got a lot of responses, everyone has an opinion..ya know!!! But only one had actually done an 84 C4 and he said..if you don’t use permatex you are going to have to get longer bolts and BTW your bracket for the spark holders won’t fit. So I knew this before I picked up the valve covers (but not before I ordered the set from the supplier).
Why I didn’t go with the permatex solution was the amount of space and jostling what I had to do when I took them out. I was pretty sure getting them back in would be worse and the changes of wiping off the some of the permatex and messing up the seal, making the odds of redoing it high.
Finding the longer bolt took some doing. The auto parts store…yes..yes.. the same one that said they didn’t have anything but cork and when querying another employee show me what I and originally asked for..didn’t have the proper bolts. The 84 C4 was all metric, bolts and nuts, you can even switch the digital the dash from US to metric. The heads are 11mm the threads were 6mm and the pitch was 1/4.
I ended up at ACE hardware and the only thing that would work and look good were the chrome. Ok…average guy with average budget…warning..they weren’t cheap…I know that when the manger took me to the back of the store and showed me a stack of boxes that were padlocked shut. They lock them up!!!! They were over $2.00 each, washers were nearly a $1.00.
So I decided on the chrome but they only had 7 bolts..I needed eight with washers as well, they only had 1 washer. When did we as a nation have a shortage chrome??? Any way I went ot another Ace and the guy there didn’t have any, but tried to tell me the ones I purchased at the other ACE wasn’t correct. He had the washers so I picked those up and traveled to the next ACE (they’re a lot like Walgreens..they’re on nearly every corner here in Tucson).
Replacing the covers was about the same as removing them and while doing it I was very glad I didn’t use the permatex, most of it wouldn’t have made it on the covers or the engine. I’m thinking at the GM factory they put the valve covers on before the AC and all the vacuum hoses and alternator…etc.
Tomorrow I’ll finish this up….well maybe…one more lesson was in store.
Thanks for reading.

Here the next installment of the removal of the valve cover. There is very little room in this engine compartment, as compared to my 70 Mustang, and I had to remove a few things to just get the covers out.
But first a couple of mistaken assumptions I need to clear up. GM did not use cork from in the factory for the 84 vettes. They used Permatex sealer gasket maker. I got that wrong. Carrying on with that assumption as I viewed the old material in one of the videos, I suggested that the gasket had been replaced once before. That was based on the previous assumption that the factory used cork..in fact, what you will see in the video (post that one tomorrow) is the original factory seal. With 64k original mile, I’m guessing that is correct. (Learning is good…oh and don’t worry..I have one more lesson to share…..sigh)
These next photo shows how tight it is on the right side of the engine.
The black outline shows the span of the valve cover. The white shows the pieces that have to be removed.
There are a couple videos coming up andlet me tell you that aren’t great… its tough to record with one hand and work with the other…oh…well…you’ll see.
This next video shows the air cleaner coming off and a vacuum hose.
This next video is more of the same.
errrk.. I’ve learned that this blog take a while for video to process so I’ll have more video loaded tomorrow….errrk.
Of all the parts I had to remove on the right side the worse (meaning it’ll cost me later) was the A/C electrical sensor. You can see that in the picture above circled in white. Yeah….I know why the garage wanted $700.00 to replace these…..
More coming up tomorrow.

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.

Often if you get the right size radiator or heater hose it will be a tight fit(eerrrkkk….don’t tighten the clamp first!!!!….just kidding…eeerrrkk) getting it over metal fittings. You can buy them bigger but you are asking for leaks!!!! Here are a couple of tips. One I’ve used and the other I haven’t tried yet.
1. I live in Arizona, and it’s hot here and normally if you are going to have problems it will be from over heating in the summer time. I’ll take the hose and leave it on the concrete driveway for a while in the hot sun. That often softens it up enough to slip on.
2. This one I have not tried. If you have clear wire-pulling compound, you can rub a light amount around the inside of the hoses and it will slide right on. Here is a link where you can find some. http://www.twacomm.com/catalog/dept_id_608.htm

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.
