I'm overhauling my 94 DOHC engine again, and as I look at ROck-Auto's web site, I notice that they have THREE choices for rear-main seal available. Since the mains on the Saturn DOHC engines are usually leakers, I guess they are designed to address the problem. One is an "improved design" from Fel Pro that is a couple of millimeters thicker. One is made of Viton. The last one says it's made of PTFE. Now I don't know which of them to get. Does anybody have any idea which is likely to be the best?
