440 valve cover gaskets

[blinkey]

   Trying on my 69  440 to put the valve covers on 3 times and they still leak,,,,,any secrets out there? Im useing the rubber ones

[303 Mopar]

Every rubber gasket I have tried leaked.  Go with cork with the thin metal band in the middle.

I bought the same ones and they look awesome! Won't know how well they work for a long time to come though but I'm optimistic.

I finally got mine to stop leaking with cheapo fel-pro cork gaskets and a thin sheen of rtv

   Do you use the permatex on its own , or with a gasket

With a gasket.

I installed my valve covers that last time in 1989. Cheapest cork gasket sold and I can't even remember if I put my old aviation gasket sealer on them. Still not leaking on car pull down.

Remember, do not over tighten the bolts!

Pricey though, and that price is for one side only.

  steel core rubber (blue ) , put copper  on both sides fit and do up finger tight, let set overnight and torque to spec

I have these permatexed to the valve cover only. I can take it off and put it back on anytime. NO LEAKS

[blinkey]

Sounds good I found the permatex gold. Now what should I use to clean the oil with on the valve cover and head.,,,,,varsol?

[PlainfieldCharger]

I like to use Naptha. It is a strong cleaner that leaves no residue. You can get it at a Hardware store.

Interesting.  I've never used a sealant of any type on valve covers.

I have eddy heads, and alum cal custom valve covers.  I use cork and they seal great.  I also use a stud kit for the hardware.   no more leaks for me and I keep a stock of gaskets in the garage just in case.   reusable is never really reusuable they leak for a reason

[miller time]

Cork and black rtv with some brake clean on a rag and your good,  if you have stainless valve cover bolts, IMMEDIATELY put them in the trash!!
I put grade 8 bolts and stainless washers, that way if you over torque them by 2 lbs they won't snap off like stainless, its worth a $5 dollars and hassle, oh and some never seize, especially if you have a aluminum heads like me

Here was something I found after I put my gaskets on...
This must be your reasoning...

no need for sealant for you crush the cork without killing it.  I replace them every spring and mid summer to give the aluminum valve covers a good deep cleaning.  haven't used sealant in years.  I know some like spray adhesive to keep the gasket in place but I moved on to studs the never move on me now.

[blinkey]

Thats a great idea. Are you using 6 studs, slide the gasket on , then place the valve cover on. That way gasket stays put
