oil problem on my MPT70 TURBO...
WELL today i was checking on the turbo and spoted some oil on the turbine down pipe the hot part to the muffler so it could be the drain on the turbo i have the drain to the valve cover its a front mount turbo and i have a flange with a small hole to feed it and i took it off and cleaned it and i blew in the oil feed flange and cover the drain flange and air was coming threw the back side and not the front just the turbine like a leak or something is this normal for air to come out to the turbine not alot , so what could be the problem the turbo is brand new i just install it 2 days ago . thanks by the way for your help.

You have too much oil feeding into the turbo. You either have too much pressure or too high a flow of oil. The turbo only needs a small steady flow of oil to the bushings. When the center housing gets too full the excess oil runs by the end seals into the turbine and probably the compressor. You can fix it by adding a restrictor in the oil feed line before the turbo. Some of the guys are using N2O jets or pills I think and some as small as 0.050". Do a search on here and you should find some more general information. If the oil gets into your compressor it will get on your MAF (if you have one) and screw it up.

Couple of questions...
1. What size is your drain line?
2. What size is your feed line?
3. What are you idle and high RPM oil pressures?
4. You said your drain line goes into the valve cover...do you have a picture? Is it a downhill slope the entire way? No flat spots or uphill spots?

The sealing rings might have a crack.
How large is the drain line as well.

Its really easy just to drill and tap a hole no worries about welding or redesigning your dipstick area.
