Oil In Your Turbochargers Turbine? Diagnosing and Common Causes.

[@ssss-df5qz]

Would a badly leaking exhaust flange just before the turbine cause heavy oil leaks on the compressor side? Enough to fill the cooler? Had an IX35 over run on me with a recon turbo fitted. Everything checks out, return, feed, case pressure, case vent, air filter. Only thing I noticed is the exhaust flange of the turbo was leaking where the bolts let go. I assume high RPM with minimal gases going past the turbine not spinning the compressor fast enough to create pressure, would suffer vacuum and suck the oil out? I dunno, it's driving me a bit mad. Never had a turbo fitment go wrong.

What about when you have your crankcase vented to atmosphere with breather but CcV still intact (recently replaced as well), and you get white smoke until it rises in temperature? Pickup is deleted 6.7, assuming the turbine side oil seal is compromised? VGT seems to function flawlessly, was deleted at 35k and showed up around 60k

I have a new turbo on my truck, previous turbos were leaking bad. I’m getting oil at the intake plenum area by the grid heater. What are the chances this is from just oil buildup being pushed through the intercooler?

Not truck related but what if you have a turbo that has a electric actuator that controls the waste gate and the turbo is failing and over boosting would this cause oil to go though the air intake? My car has a ccv which I have replaced and I can see little oil to the turbo from there there which I believe is in the normal range. My turbo actuator makes a buzzing noise and boost is strange I think it's over boosting. My exhaust dpf and air intake throttle is getting covered in a alot of oil and I believe this is cause my diesel car to missfire also. I have a oil leak externally that I believe is under the turbo so be either the turbo or feed/return I'm not sure yet till I dismantle. I don't think I have excessive crank case pressure, I just don't understand why so much oil is going through the turbo as it can only get there from the feed. If it was over boosting as I mention would this do this? Or does this seem like it's a common case of turbo seals failing? My only gripe with oil seals failing is why is it also leaking externally.

Awesome. Very clear!
