I am replacing the dried up cork gasket on the pushrod cover on the ol' WD. Any tips as far as using permatex or should I just put it on without any?

Glue it to cover with 3M1099 glue or that yellow weather stripping glue. Let it set over night with weight on it to keep it in place. Install next morning. MACK

I've been messing with this stuff for 50+ years now; my Dad always used Permatex Aviation #2 gasket sealer. It is messy, sticky, gets on your fingers, in your hair and is miserable to scrape off the next time.
But it works.
When I got out on my own I read about folks saying that a properly prepared gasket surface didn't need goop to seal, so I tried and failed. I tried silicones and I tried various things with varied results.
When I really, truly don't want to mess with it for a long time I still go back to Permatex aviation gasket sealer.
Your mileage may vary.
Good luck :-)

X2 for Les Kerf. I know different methods and sealers will bring results but in my opinion Permatex Aviation is at the top of the success list. Silicone Ultra Grey will really resist oil leaks. Using Permatex Aviation on both sides makes an awesome seal but the gasket is rarely reusable if you remove the part again in the future.

When my Dad was a dealer, he would shelack the gasket to the cover and then grease the block side. This was so he could get the cover back off if valves needed readjusting. He never had a problem!!!!

Indian Head Gasket shellac is my go-to on cork gaskets.

if ya do like Mack says,, that gasket will defiantly stay on the piece its glued to. I like the permatex aviation or whatever is similar, it stays kinda soft and seems to seal decent,,,

Yup I did as Mack said and it worked great. Man was there a lot of old sludge behind that cover and the old cork gasket was rock hard and brittle.

I think that is why they had that cover removeable was to be able to clean the engine due to non-detergent oils.
