So I have been racing my car with a drip from the rear main seal or retainer or possibly the oil pan gaskets, So last weekend I put a Mancini retainer and seal in and new good oil pan gaskets and we took it out for a few test pulls and get it back in the shop and it still has a couple drips hanging off the bell. I just cant see with how nice it all went together that it could possibly leak. Now I am thinking it has to much crank case pressure. I have a big k&N breather on each valve cover and no pcv. Would a crank case evac to the headers fix this drip?
