There is oil coming from the bottom of my bellhousing and that semi-circular plate that attaches to the bellhousing. Within 6 hours of parking my car, there is a quarter-sized puddle of oil on the garage floor.

The problem is that I replaced the rear main seal Friday to fix the leak! I have a brand new Fel-Pro seal in there and the leaking continues. The two semi-circular gaskets behind the rear main seal (I don't know their names) were not leaking. My oil pan is dry so I don't think that the pan gasket is leaking.

Anyone have any ideas on what is causing this leak?

 

I did just switch to Mobil 1 15W50 from regular 10W30 last oil change. This is stretching it because I just put the new seal in, but should I maybe wait a couple oil changes to do something, hoping that the leak will disappear?

 

you sure it's not the oil sender leaking, intake, or a valve cover? all would drip and run down the back of the engine.

 

another check....distributor..

 

clean off all the oil on the engine and oi pan and then run it again watch for leaks. i sesond al the other problem areas mentioned above.
