Please help me figure out my oil leak. I had to skip my last run at my last HPDE due to an engine oil leak…lost between 1/2 and 3/4 of a quart in one 25 minute session. The leak seems much more pronounced under heavy loads since the car didn’t leak much on my 1.5 hour drive home from the Summit.
The leak is at the bottom of the bell housing on the transmission and drips pretty heavily when the car is driven hard. I pulled the inspection plate on the transmission, but wasn’t able to tell if it was coming from the oil pan gasket or the rear main seal.
FYI, I replaced the oil pan gasket about two years ago. I also replaced the clutch and rear main seal (RMS). After replacing the RMS, I noticed an oil leak from the bellhousing. Went back and did the RMS again and haven’t had a problem until now. Not sure if it matters, but I bottomed out the car going over a pothole a few weeks before the HPDE. However, I do have a heavy duty skid plate installed.
Any suggestions on diagnosing the oil leak? Also, I’ve read that there are two types of RMS. I have a rebuilt engine. Could it be possible that I installed the RMS? Thanks.
