My truck has developed a fairly significant oil leak that seems to be towards the back of the engine. I have ruled out oil pressure sending unit and distributor. Can't seem to find any leaks at valve covers either.
My mechanic friend suggested it is most likely rear main seal (he has not seen the truck "in person"). I tried removing the flywheel cover to have a closer look, but this seems not possible without removing the exhaust that runs across right underneath.
I was however able to sneak in my cell phone to snap some pictures.
There is a bit of oil at the bottom of the cover, but to my untrained eyes it does otherwise look pretty dry in there, especially considering that the leak is big enough to leave a pool on the ground every day.
Should I still assume that the leak could be from the rear main seal, or can I rule it out?
You can see the oil all around the outside perimeter of the cover.
IF the leak was from somewhere else, i.e. oil filter adapter, is it possibly that the oil could get inside the cover and leave that small pool on the bottom?
