The reason in ask these questions is i just had my engine freshened and im ready to race then noticed a puddle on oil under car put it in the air and looked between bellhouseing and pan and saw it lightly spraying up near the rearmain/oilpan when running.doesnt leak when sitting and i have a race coming up need to fix asap and my engine builder is nowhere to be found so im in limbo of what seals in have.
