stubborn oil leak discovery 1 1998

All, need some advice,

I have this leak! The seems to accumlate and drip at the bottom center point right between the transmission and the engine.

It drips after I drive the discovery and it does it every time.

I have replaced valve cover gaskets, and replaced the oil pan gasket as well.

I've checked the rear main crank shaft seal (thru the port hole) and its dry in there.

Any where else I should be directing the search.

It seems like quite a drip but cant seem to find the source.

Is there any lines, etc in the back that I am not seeing.

Any help is greatly appreciated.

Most likely the rear main cap cross seals. I have a 98 also and I'm about to do head gaskets,front cover, oil pan, cross seals & rebuild my oil cooler lines. I'll probably reseal my diff's & t/box at a later date.

Are you 100% sure its engine oil?
