Major Oil Leak.??
A friend of mine has had some major oil leak problem for the last few days. He asked me to come over and I was shocked to see so much oil coming out of a car.
He has a stock 99' Z (90K mi) and it appears to be leaking from the driver side rear of the engine. When the car is off it drips oil a little here and there but once it's running, it starts streaming oil almost immediately.
The only thing I can think of is a rear main seal but I can't imagine so much oil coming out. We checked plugs, valve covers, oil sending unit and a few other misc. things and still have no idea what or where it is coming from. This is his DD so we are trying to get him back on the road.
ANY HELP IS GREATLY APPRECIATED.!
Cheers.

I would check the oil pressure sending unit. It's located on the top rear of the engine just behind the intake manifold on the driver's side.
Here's a picture of it. It's the black round post thing sticking up in the back - has a white elec connector:

You said driver's side so unlikely it is the oil dipstick tube that has worked it way out of the block because the bolt fell out or the clamp is broken.
But without the dispstick tube inserted completely into the block it will make a mess of your engine bay in a hurry and also give you false oil readings on the dispstick.

Oil is coming down from the mid to upper rear of the engine and coming down the bell housing. I have a hard time believing it is the rear main.

Torque the oil pressure sending unit!!! Get the right adapter and get that sucker on tight! I had that EXACT same problem. A TON of oil was coming out, so much that it was ejecting from the sender, leaving it bone dry. Like it baffled me until I went out bought the socket adapter and torqued it down. No more oil
