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…..
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.
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.
Hey..don’t forget the Project Car Contest $100 online gift car to an auto parts house.
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….. 🙂
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. 🙂
So the process was fairly straight forward. Only thing not obvious was the removal of two trim pieces that hid the front bracket.
Philips screw..wow how ugly was that old dash???
Top screw removal
There were 3 philips screws along the dash next to the windshield. A nice long screw driver worked nicely. The holes in the dash cover for the screw were pretty deteriorated, but it was good do know that the dash was really metal covered with the padded vinyl so the screw would hold forever.
passenger side screws – remove and done!
There were 4 more screw on the passenger’s side. Now if this were a Mach I it would have a clock located there, but instead there is just a plastic panel. You could actually place a LCD monitor there for DVD player. The panel is below:
passenger’s Side Panel
The next set of two screws that needed to come up were located above the radio. These were a bit awkward to remove. But they weren’t philips screws..that pieced together with what we found after taking the dash pad out led to a conclusion of…well I’ll hold off mentioning that until I give you the other piece.
Arrows show the position of the two screws
After removing these two “non-philips” screws (flat) the dash pad would lean forward and you’d think it would pop right off …but nope!!! The next photos show why.
Dash Pad leaning forward.
Additional Trim piece that needed to be removed.
One screw and off it came.
Caption is wrong here the side screw was removed but there was still one below.
Bottom screw had to just be loosened and the pieces sliped off
One this pieces of trim was removed you can see the screw/bolt that need to be removed.
Not a great pic..but you get the idea.
One on each side and the dash pad was ready to go. Check out the videos. If the videos don’t work..let me know.
I enlisted the help of my son Ryan. He was over for dinner and he lent me hand, so I could film as well.
This first video shows us discovering the front brace hidden under the trim piece.
Here is the backside of dash pad.
The paper tag on the bottom of the dash pad.
Reading that you can see the date of 1972 on the tag. Since the Mustang is a 1970, the date doesn’t make sense. Adding that the screws near the radio that don’t match (straight vs. philip for the rest) I wondering if the dash wasn’t replaced. The original owners didn’t mention it, but there was no real reason too. This could mean that the dash was replaced with what appears to be NOS (new old stock) (from 1972)..that’s a possibility. I’ll do some more research just to find out.
The last few pics are of the other markings.
The two eights – one upper in maker and the one in the glue.
Parts code perhaps 3 24 (d) 2
Sorry..that one’s upside down. 🙂
The original Ford speaker.
Speaker with part number.
So what’s next? I’ll check out the wiring and pull the gages if I need to for repair (although all the gages are working fine). Oh..yeah..do a bulb replacement.
Many of our cars have worn out emblems that were once painted…Ok..I’m a lucky average guy…the Mustang’s emblems are all chrome and my Corvettes are mostly plastic.
But what about some those that need painting. Look for a flow pencil.
Flow Pencil for paint your emblems.
These are pretty reasonable and make painting small areas a bit easier.
