1st post valve cover gasket

So I'm finally getting around to posting my first thread here. I've been getting advice and looking at all of the cool stuff that everyone is doing. So I'm am finally getting around to replacing my leaky valve cover gasket, which most of you with a 258 have done at least once. It has been leaking ever since I got it off of the PO but it has never bothered me much. When I never had a breather on it before so I went out and got one and put it on. Then I lost about 3 quarts of oil... lol. So time to replace it.

What it looked like to start


Lovely oil still sitting on the head

Nice view of my springs and lifters

Valve cover after I cleaned it

So here are the bolts that came out of it


So While going through the process of taking off the valve cover I found that all but one of the bolts were lose, go figure. The PO did replace the valve cover with an aftermarket one and he put a quark gasket on it. He did put RTV on it but only on one side. Its getting late so I decided to stop for the night. Tomorrow I will go get all new stainless bolts, since mine are all rusty and the PO decided to throw a random bolt into the mix. Tomorrow I will clean where the gasket sits with acitone and put the new gasket on with some high temp RTV.
Please feel free to give me any tips on making this work the first time I do it.

Patience patience patience. 1st make sure the new bolts you buy fit and thread without problems. Buy an inch-lb torque wrench and a decent set of long allen sockets from Harbor Freight - about $30 total if I remember correctly. Put black RTV on the cover, then place the new gasket on it and let it sit for 15-30min making sure all the holes are aligned. Put black RTV on the head and place the cover/gasket on it gently. Tighten the new bolts to finger tight and allow that to sit for 4 hours. Drink a few beers, watch the news. After 4 hours, come back and tighten to half whatever the torque specs were in a pattern radiating from the center out to the end bolts. Let that sit overnight. In the morning, torque to full specs in the same radiating pattern. Check the torque daily after driving for a week or so, then again in another week.

Basically, you never want to rush RTV sealant, or else it'll leak again. Oil will mix with the sealant and then find it's way out everywhere.

I have the same valve cover and gasket.

Apply the gasket to the valve cover using a 'High Tack' gasket adhesive and do not use RTV sealant as it is not needed. You actually only want to glue the gasket to the cover.
When putting on the new valve cover with the cork gasket attached to it, smear a thin layer of grease on the bottom of the gasket that will make contact with the cylinder head. The grease will seal the cork and keep it pliable and easy to remove later on if need be. Never had a valve cover leak with this method and always torque the screws to spec and use a Serrated type lock washer for the bolts.

I use acetone to clean the head and valve cover, then use rubber contact cement with a felro gasket to seal it.

I'm with Keith, no RTV for me. If you can't get the valve cover to seal without RTV you should probably take a good look at the cover.

Hey GMACK, I dug this post up in a search. I'm about to change out my gasket to repair a nasty leak like yours, and (hopefully) rule out a RMS leak. So I was wondering, a few months here afterwards, which of these methods did you try, and how has the new gasket held up?

I put rtv on the top and bottom of the gasket. I bought new stainless bolts and tightened it down a little bit then let it sit for a day then tightened it again and it has held great so far. I let it sit for one more day after the second tightening then I pulled the bolts and put thread lock on them bc my previous bolts were loose when I went to take the valve cover off. I'm sure the other ways work great as well but that's just how I ended up doing it. Hope this helps

Yeah I'm with the others here. I don't use rtv on a cork gasket. The factory never did it either. Sometimes I put a little 3m weather sealant on the valve cover side just to hold it in place. The cork itself creates the seal. I've never used rtv except where specifically specified by the manual and the only place the manual says to use it is on the 2 piece RMS that I can think of. I also don't have any leaks on the engine I rebuilt 2 years ago using this method.

Hi, GMACK,
I'm in Summerville.
Glad you haven't had any more trouble with the VC gasket, I also use just a little RTV on the cork gaskets too.

Bert...
