Hi, I have an NA s4 and I can't decide if this is the correct gasket. I purchased rebuild kit A from Atkins and not sure if I should use the provided front cover gasket? Its not machined for the Teflon o ring, but it seems like theres a large hole on this gasket, see picture. Can I just trim off the portion of the gasket over the o ring, and keep the outer perimeter for sealing? want as much compression as possible over this o ring. Suggestion please.

Also, having a hard time choosing the correct o rings. This kit came with two O rings that i'm not sure if it's for the front cover. There's another O ring that is slightly smaller in diameter and thicker. Should I use that one for more compression/better seal? or does the one I have in the picture look correct.

 

Just send the gasket back, they sent me the wrong one as well
Ya kinda have to have the right one, if you want oil pressure that is

 

86-92 Front Cover "O"-Ring

 

I thought i'm suppose to use the 79-85 gasket? Not sure if this is the big/old style gasket.
