Dan, I thought my leak was the pan, but turned out to be the vacuum/steering pump seal, and the oil migrates back the pan. I know it's prob a little late since the post is almost a yr old!

when those leak you have a drip off the oil pan though and not off the bellhousing. the rear of my oil pan gasket has the ever so slightest leak going on its up top on the oil pan butted up against the rear of the engine where the bellhousing meets up. im about 99% sure its the oil pan as when i clean it and watch it, i see it come from there and i just did the rear main as well

You dont need to remove the cross member, hook a engine hoist to your 2 hangers located near the head and lift the engine up till the valve covers hit the fire wall and you can get to the oil pan easier that way , also disconnect your 2 drive shafts when you do that

I know exactly what ya mean, the junction of the rear seal housing and the block is good for leaking if not sealed up good. What happened to mine is the oil was dripping from the vac. pump and blowing back when going down the road, that's how it was getting on the bellhousing, even the slave cylinder and front driveshaft.
