For rear main seal, try one of the oil seal repair fluids. Can't remember the number but ATP makes one. Blue devil also do one. I have used both and they worked.

Oil lines to turbo are a pain, but a common issue.

My question is why do they only leak when the car has been driven,it can sit and idle for 30 minutes and does not leak a drop but when I drive it then come back and look under the car it is on top of the drive shaft and then slung everywhere.

The ones you are referring to,the turbo lines,they have the double copper compression washer/gasket correct/ I just got them in yesterday,i ordered them last week in case they were leaking,it does not look like they are leaking at all but it has to come from somewhere and why does the oil dipstick still show full if it is oil that's leaking?

The oil drain line has a gasket on the bottom of the turbo, and a rubber oRing on the oil pan/block (Just above the oil pan)

When mine went.....it got oil all over the driveshaaft which sprays it all over the rear (right) of the engine

:D
