I think my turbo seals are leaking oil.

There is little to no blow by and the engine runs fine. The first indication is there is oil seeping out of the cross over on the intake. The next indication is there is oily soot in the tail pipe. I don't have much experience with the turbo engines and is this normal? It only smokes at startup. More so than any NA engine I have worked on.

I would let this ride but with the oily residue in the tail pipe this is going to be an issue where it will poison or plug the catalytic converter. What step would be best to check the turbo seal? I am assuming the turbine side is leaking along with the compressor side. Also are these turbos known to leak?

Im 3 for 3 all leaking. Id buy the $100 cartridge on epay and be done with that. 1 hour job. If you want to see the leak, take the cartridge off and fill the oil holes with water.

Remember that if too much oil begins to leak, the engine will use that oil as fuel and you can get a runaway engine. Fixing the problem by replacing the cartridge is prudent.

So is there a better cartage to buy or just find the cheapest one I can find?

As for the oil and runaway. I know diesels can do this but I don't think this is too much an issue with these. After all it's not a 2 cycle Detroit with a blower and a turbo
