I've had a considerable oil leak coming off of the bell housing on the back of my engine for some time. At first I suspected a rear main seal however, after taking a look at the torque converter, it was dry. So, I suspect that there is something else leaking and dripping down the back of the engine. It is collecting just below the plastic plug for the hole you would use to remove the flexplate bolts.

Admittedly, I need to clean that area and look for new leaks as it has been leaking there for years.

My first thought is the turbo oil feed line. Can anyone think of any other things to check in that area?

When I first bought My car it was covered with layers of dirt and grim and I had a leak back there.
After three Cans of Engine degreaser (I had to do the Transmission also) it turned out it was 98% a Valve Cover Gasket Leak. But, I could not see that until I cleaned the Engine.

If it is the Oil Feed Line they tend to leak at the bracket at the back of the Head. The Rubber wears off of the Bracket and vibration cuts into the Tube.
A small hole there can be repaired.

Clean off that area well and the area above where the Valve cover is and go for a drive and see what is wet and leaking.

Strange, I installed an air/oil separator and my big leak disappeared. I still have a little drippage there but the large deluge of oil has stopped. I have a feeling the blowby was forcing oil out from somewhere. Time to button up the small leaks and call it a day.

That seems reasonable.
