bad seal or oil return line??
we have a t28 mounted to a hf manifold.guy wanted to keep his a/c so we had to make an adaptor to turn the turbo.this placed the turbo very low when compared to the oil pan.so the length on the line is short and it is mounted very low in the oil pan.
the car smokes,very badly.it coming from the turbo becuase there is no oil at all in any of the pipes any where or on the plugs any where.
question:is it the seal on the turbo from the oil return line?
question:if i fix the line,does the turbo need a rebuild?
question:since space is very limited,could i run the line to the back of the pan like on the greddy kits that use the oil plug?
its oil smoking into the exhaust piping but nothing through the comp side,does that sound like a seal leaking from the oil return side?

This is what I had to change in my engine when I first got it. The return line was below the oil level of the pan. Put it above the oil level no more smoke. Problem solved.
Good Luck

Re: bad seal or oil return line?? (RA166E)
how did you figure out where the oil level is at?i have almost no room to move it or else fitting will be to high to have a downward slopeto drain.its in a sohc ,just how far is too low?

AN4 is going to cause to mouch pressure in the turbo, I'd switch to a AN3 I had to becasue too much volume of oil

Re: bad seal or oil return line?? (civictypenos)
i had the exact same prob your having. mine was smoking so bad i would get pulled over, it was really bad. the prob was that the return line was both too small diameter and it wasnt above the oil line causing back pressure in the turbo and burning it off when it couldnt push it out fast enough. i got a bigger hose and put it highest up on the oil pan as possible and BAM, no more probs. and no turbo damage either, but i took care of it it like 6 or so days after it was originally installed.

Re: bad seal or oil return line?? (civictypenos)
finally had time to jack the car up and check it out.the return line is at the bottom of the pan.there is oil around the turbo housing as well where it joins to the exhaust side.in this pic you can see right where the turbo joins,the oil is seeping around the joint.

Re: bad seal or oil return line?? (turbopimp)
very nice,thanx alot.
to those of you who did have this problem,did your turbo have the same looking leak as mine?between the exhaust housing and the center section.

Re: bad seal or oil return line?? (civictypenos)
bringing this thread back from the dead because my turbo looks exactly like that turbo...my drain is just like the one above though correctly, the only thing is that it kinda sits going sideways to clear the dp...what other possibilities is there besides bad oil return line?...bad seals?...no oil in my pipes though

Re: bad seal or oil return line?? (cmGSR916)
To determine the proper entry point for your oil return line, two things are critical.
1. It must be downhill all the way from the outlet of the turbo, all the way into the oil pan. All Downhill!
2. The entry point into the pan must be above the level of the oil in the pan. This is not only for the oil to be able to drain into the pan downhill, but for blow-by issues as well.
To determine the entry point on the pan. Remove the pan from the engine. Clean it out. Position the p[an where it approximates the tilt it is installed at on the engine. Fill it with the equivalent amount of liquid of your choice (like water, oil, etc.). Then pick a point on the pan, above the level of the liquid and centered between two pan bolts. Also be aware of any baffling in the inside of the pan.
(Shameless Plug Alert)
For -10 AN installs, where punching a huge hole in the pan is not desired, you can use on of these drain flange fittings, bolted through the pan wall.
