Oil Filter Plate

Yes, check EVERYWHERE
Wrap a paper towel around it, tape it off and go for a spin
Then remove the towel and see, is the oil on the inside or on the outside?

I THOUGHT I had a leaking plate
Even went with the Canton plate, and it still leaked...because it wasn't the plate, it never was

I had a bad rear main seal, and the oil fell onto the converter which swung it back up and guess where it landed?
