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?



If you run a full exhaust I would say dont bother
with the exhaust style evac... greater than 5"hg back
pressure will cause the exhaust to back up, burn out
the check valve and start pressurizing the crank case
