Help with oil leak
Can ya all gimme some guidance here. I have an oil leak somewhere and I can't find it. The top half of the engine looks good, I've replaced the valve cover gaskets and no leaks there. I've looked at the two round plugs in the back of the engine, nothing there. Can't see any oil looking down from the top of the engine anywhere. Can't really see where the oil is coming from when looking up at the engine. Car has 166k miles.

I hope not, how can I tell?
Edit: If it was a rear crank seal, would I have oil under the oil pan?

I had that issue and the rear seal was suspect. However it turned out to be valve cover gaskets. And yes oil would collect there from either place.

The best way to trace it is to use ultraviolet dye in the oil and then use a black light to find the origin.
