Recently I overheated my engine when my tranny would not shift out of first, now I have a nice size oil leak. It is coming from the rear passenger side of the engine above the starter. I have checked the oil pan and it seems fine. I also don't think its the rear main seal, oil pressure sending unit, or dipstick tube. It looks as if it might be coming from the rear of the head. I just tried wiping everything down and I going to wait till morning to see if I see anything. Does anyone have any ideas? I'm hoping maybe just a valve cover leak, could it be anything else?

I had a similar oil leak. It turned out to be the oil pressure sending unit. It's on the top of the engine, behind the intake, near the distributor.

 

Probably a valve cover leak... the top of the head gets extremely hot, your VC gasket is probably burned to ash in the middle of the outside rail
