Excessive turbo wear?

1.5mm?? that turbo is well and truly stuffed. You should not be able to feel any play at all.

Not sure what the specified movement is (if any) but it isn't uncommon to be able to feel a bit of play in the turbo impeller in the ones I have seen. Not something we ever really have problems with here.

I thought that as the turbo bearing floats in oil when the engine is running - it's normal for a small amount of play in the shaft when there is no oil pressure. I don't recall ever checking a turbo that doesn't have a small amount of play in the bearing shaft.

Yes but a small amount of play is not 1.5mm, which is a lot. Ok run it and see what happens, it should boost at 1.05 bar or 15psi at 2500 rpm with power on ie. going up a hill. It is possible that the turbo will work OK, though it may pass a bit of oil through into the inlet. If it boosts ok, you can maybe put up with the oil consumption.

Well boosting is OK, 15 psi and holding which I believe is good. In the process of going through the car, I changed the air and fuel filters. This has made a big improvement, but also I cleaned the sediment filter. I could not believe the amount of deposits in there, obviously not been looked at too much!

Sound`s familiar to me,

i not long ago had to replace the turbo on my D2, no power, smoke. I took mine to an engine specialist who got thier turbo man to look at it.

Not good news only a very small amount of play left the turbo requiring an overhaul. One of the things to check is the intercooler pipes both of mine had oil

in, not good at all this can lead to your engine going pop due to the oil being fed into the cylinder by the intercooler. If oil is in your pipes and intercooler i`d

advise taking them off and giving them a good flush with petrol. Well worth the effort.

GOOD LUCK

Bear in mind though, a little bit of oil in the turbo pipes is normal on most turbo engines and is the reason that cleaning the intercooler is specified at the major services (about every 48k miles or something I think). Flippin great big wodges of black gunge is not normal :)

I`m inclined to agree with Jim, when i got my turbo back after the overhaul there didn`t seem to be any side to side movement at all.

Intercooler pipes are not too bad, but I will check the intercooler. I spoke to the previous owner who said that they had a bad experience with the vege diesel, had to replace the pumps and I think that explains the black gunge.
