I'm going to be tearing my top end off (again) and go deeper because I noticed a small oil leak from the RH valve cover gasket. I have the replacement sitting here - Fel-Pro VS50462R. It's rubber. I've done these in the past but they were all cork.
Do I need to use sealant on these rubber ones or is the compression adequate?
