    ok it seems as if my oil pan is leaking from the oil return line i welded a steel bushing in it and put water in it to see if it would leak before i put it back on and it didn't but now when in WOT the exhaust blows out a lot of blue smoke and when i get home and look under the car there's oil dripping off the bottom of the pan i thought it was the return line so I sealed the threads with Teflon tape and it still looks like its leaking from that spot so any input or advice would be great

    If at WOT its blowing blue smoke that doesnt sound like your return line is leaking. it sounds like your turbo is going bad. Check for shaft play, and also clean everything off with some brake cleaner and then see where the oil is coming from. Good luck.

    Is the "black tar" just from it running rich? Is it dry and black? I would thinks its the turbo seals.. Any luck on the leak.

    do you think im burning oil because my oil return line is a -6an and its not draining fast enough? well i got a -8an from jegs im just waiting for it to get here then im going to plug my oil return line and drill a hole a little higher up hopefully it should drain faster.

    That might help. as far as the "tar" thats just a rich gas mixture no need to worry there, thats not causing the blue smoke. Try to return line and see what that does for you.
