I have a 98 TL 3.2 and I've noticed a couple of oil spots on the driveway underneath the rear of the engine. I change my own oil and also recently replaced the radiator at home as well. No leaks from any drain bolts, radiator, anything at the front of the engine. Anything else it could be other than the RMS? I have a lot of oil coming down the area above what my service manual calls the 'lower plate'.

Any leak ideas I overlooked are much appreciated!

 

It's very likely the real main seal based on the age of the car.
