Valve cover gasket

[Benthal]

I am going to be doing the orings on my 1974 Chevy C-10 Pick-up. It has a 350 small block. No A/C has heater. I need to know if I should use use cork gasket or rubber?

Use either. A cork will seal better, a rubber is re-useable and will probably last longer.

But this all depends. I've used rubber gaskets that stretched. And have been able to get cork to re-seal after I removed the valve covers.

I've heard pros & cons about both over the years.

If you plan on taking the covers off a few times then I'd probably pick the rubbers over the cork.

I like to use cork, just a personal preference. And if you plan on taking the valve covers off several times, I would replace the gaskets anyway. JMO

thanks for the reply I think I am moved to do cork. I am hearing that it seals better. That's great, but I want performance too. Do they last longer aswell?

Put a cork in it Daniel. I would use rubber gaskets if availible for my engine. Also make sure the valve cover holes are not bent down from over tighting. I guess it is one of those preferance things, I got my war paint on!

I use the stuff in a can like the factory does now. Seals the best. I don't see many leaky valve cover gaskets these days. I've tried cork, rubber, rubber w/ steel and the stuff in a can works the best. Takes a little longer to put on the valve cover (you need to wait till the material sets up) but seals fantastic.

Now boys lets play nice. !!

I'll look later. It's a rubberized gasket material in a pressurized can. Got it @ NAPA but I'm sure you can get it most anywhere. Most of the domestic car manufaturers use this kind of stuff anymore I think.

Ray......

COOL PIC......
The old fart opinion is.......... cork,.... but use the Permetex copper (high heat) sealer.

The worst palce (and the rest of you guys have to admit it) is where the heat cross over passes under the gasket. It tends to burn out any type of gasket. The real expensive rubber gasket material will usually last a tiny bit longer than cork, but have had real good luck with cork staying where I put it......
