258 Valve cover gasket question
 

Hi,

I've got a 258 engine on a '89 YJ. Unless I'm wrong about this, the original
valve cover was made of plastic but the one I have is made of aluminium (did
I spell that right).

If I'm correct in my assumptions above, will a regular NAPA gasket work with
this valve cover or do I need to find a gasket made for this particular
valve cover?

Thanks,
Nelson

Re: 258 Valve cover gasket question
 

You can get cork gaskets for either type of cover. They are different.

Some of those aluminium covers don't use any gasket, just RTV silicone.

Having the surfaces perfectly clean is the big trick. I get them super
clean, then I use a skim of RTV on both sides with a cork gasket.

The one I put in in 2000 on mine is still pretty dry and my plastic
cover only has the two bolts up top center.

I also 'think' your 89 came stock with the metal cover.

No, you did not spell that right, it's aluminum, not aluminium.
