Valve cover gasket replacement

[Car #4]

I’m replacing valve cover gaskets on a 440. I have Felpro gaskets. Should I use a little RTV or Permatex?

I used a thin bead of Ultra Black on both sides of the gasket and no leaks whatsoever.

^^^^ agree

Must be a bugger getting them back off?

Loctite 518 (sealant)

 

[zyzzyx]

Yeah, 518 Loctite on one side only! Valve cover side.

I use Permatex Hi-Tack on the valve cover side but RTV black should be good as well.

*some* engines don't need their valvecovers on and off like a hookers panties!!

Would you use the same on the transmission pan gasket?

On that I use the Mopar rigid reusable gasket.

Haven't needed to yet. Only been 2k since rebuild.

Depends on what valve covers / heads you have

Get the covers straight, and go dry with cork gaskets. Valve covers and trans pan. The factory did it this way also. And they put a warrantee on it.


I know some just can’t accept the idea, but it works.

I respect your opinion but the factory was working with brand new, straight and flat. After the covers have been off a time or three they are imperfect. I’m not opposed to a little gel.

I dapple a little permatex on the cover when using cork and let it set up a bit! trans. dry,you don't want anything getting in there!

 

[Don Frelier]

With the 68-69 hp manifolds the cork doesn't last very long. 2 years and they get dried above the exhaust ports. I can't recommend cork.

Couldn't agree more.

I always stick em on the valve covers with permatex, the head face will not stick so easy so any time you pull em off you are not ripping up the gasket and it can be reused multiple times.
I use cast alu valve covers, the stock covers might need a little closer inspection if the edges are straight and the area around to bolt holes are flat.
