    Oil on the turbine blades? :(

    I just bought a used TD04 and got to taking a look at it, and it has an oil residue on the turbine blades and housing. I can't imagine this is a good thing.

    The TD04 i just pulled off my car (100k miles) has no oil whatsoever on any part of the turbine housing/wheel. Bone dry. Of coursie it has the standard black carbon deposits, but other than that, dry.

    I was going to replace my high mileage TD04 with this newer one (30k miles) since mine was starting to eat coolant a little and whine a lot. What do you guys think? Are there any non-dead turbo reasons why there might be so much oil residue on the blades and housing?

    Or maybe the motor blew up.

    from what the guy on nasioc told me, it was ran at stock power levels until ~30k, then swapped for a bigger turbo.

    I'll try to get some pics up later. Its just a light coating of oil residue over everything. Turbine blades, the nut, the housing immediately around the turbine wheel. A light coating, but heavy enough that the blades look wet in appearance compared to the perfectly dry blades of my current stock turbo.

    I doubt its blow by. It would have to be the inverse of blowby. Like blow-suck ha. Blow-by pushes the oil out the crankcase vents, back into the intake tract. It shouldn't touch the hotside though.

    What color is the oil ? Black or redish ? What are the chances it could have been from an over oiled filter combined with blow by.

    If not check the seals.... 30K blown td04 ? Not likely. And he said he ran stock boost ?
