rebuilt engine and have had leaks. I put a t3/t4 on the car fmic, kirban regulater, bigger cam. Last night I got the boost up to around 12 maybe a little more and the breather on the valve cover came out of the vlave cover. I checked my compression it is at 150lbs. Seems like I am building pressure inside the engine causing it to force the oil out of the engine. 3 rear main seals, removed the rear main cap and applied rtv and retorqued. added a washer to oil pan bolts, and am baffeled. Anyone ever had this issue? I am on the verge of pulling the engine back out and ????? Don't know I installed new pcv but think maybe I need to get the Ford one but am not sure how much of a check valve it has vs the other ones? Again I have the potential for more with this car but the oil leaks are drving me ......
