Exclamation so now I'm thinking its NOT the rear main seal leaking oil... look at these pictures!

Alright, I thought my oil leak was from the rear main seal, but now I'm having my doubts. The back of the oil pan doesnt seem to be wet. There is oil collecting on either side of the block near the bottom. I have circled in red the places where the oil is collecting.

What do you guys think?

Oh yeah, I have ruled out the intake manifold or valve covers leaking. Way up there seems dry. I checked it from the back (becuase the transmission is out right now and I can get to it from the back).

could be the dipstick I guess..

I dunno if I put too much oil in it when I did my oil change too... maybe it was overfull and leaking out somewhere

I have the same looking leak you have.. I replced the valve cover gaskets, oil pressure sender(what a pita), intake manifold gasket twice, rear main about 2 weeks ago when i did my clutch, oil pan about 4 days ago.. im still battling with it.. the front of my oil pan is clean, its only on the back, and my starter has some oil on it, along with the other side of the block, let me know if you want pictures.. My dipstick was leaking too, sealed that up though and still leaking..
