Can boost cause oil leak from rear main?
Ok so about two days ago I put a engine in my car that I fully resealed and today while I was parked I noticed a puddle of oil forming. I checked the cas, oil lines and my oil filter and it was all dry. When I replaced the rear main I made sure it was flush and the oil pan had new grey rtv applied. There are no other leaks around the motor and oil pan and its only coming from the back area. I know its not trans fluid cause it didn't smell like it and my oil level was really low. So my question is could my pcv be bad and when im in boost its pressurizing my crank causing oil to be pushed thru the rear main? I currently have the car tilted up and oil is still dripping from the weep hole.

Ok so it wasn’t the rear main seal. It was the seal underneath it. It was a new seal. I compared it to the original seal and it was thicker than the oem one. When I torqued the pan down it was sitting correct I guess the vibrations cause it to squeeze out of the cut out in the center. The missing piece was in the bellhousing. Anyways I slapped in the oem seal and now it’s all good. No more leaks for now.
