I'll share my experience. So I've been chasing what I thought was a rear main leak for about 6 years. I figured I'd start by dropping the oil pan and re-sealing it, which I did. That did not help. This year clutch was replaced. The rear main in there had a tiny leak, not enough to drip. Replaced rear main. The leak is still there. Finally have traced it down to the front crank seal/timing cover. (I hope). The way the oil runs will make it look like it's from the back. Since it's been doing it the last 6 years, it's coated the bottom of the pan, and finally the clearcoat is all coming off. Once I replace the two things in the front I'll be re painting the pan on the truck. But back to how the oil leak is running...it's actually running between the block and the oil pan, right on the outside of the rtv/oil pan gasket. But since it's in that "sandwich" area, it really doesn't get on much except some bolt heads on the driver's side (and bottom of the pan). Here is where the leak ends up, giving the appearance of something coming from the back end when it's really originating from the front. It's been 6 years with this leak, and it hardly drips at all in the driveway, but over the last 10k miles, I'll lose about a quart and a half
NExt couple weekend I'll be pulling the timing cover.
