WALRO Posted July 11, 2007 Share Posted July 11, 2007 just checking the play on the turbo (TDI 300), and seems to be excessive side to side play, maybe 1.5mm. I know you get a little bit of end float, but the side to side seems too much. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted July 11, 2007 Share Posted July 11, 2007 That does sound a wee bit slack - is there a problem you are investigating or was it just a wiggle you did while you were passing? If it works I would probably leave it alone... Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted July 11, 2007 Share Posted July 11, 2007 1.5mm?? that turbo is well and truly stuffed. You should not be able to feel any play at all. Quote Link to comment Share on other sites More sharing options...
WALRO Posted July 11, 2007 Author Share Posted July 11, 2007 I am investigating the turbo, as the motor seems dead. I recently bought the car, my first Discovery. I just got a T piece tonight to fit a boost gauge, so that is my next step. Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
Les Henson Posted July 11, 2007 Share Posted July 11, 2007 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. Les. Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted July 11, 2007 Share Posted July 11, 2007 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.

WALRO Posted July 12, 2007 Author Share Posted July 12, 2007 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! Quote Link to comment Share on other sites More sharing options...

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 Foxminer.

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 Quote Link to comment Share on other sites More sharing options...
RRX Posted July 14, 2007 Share Posted July 14, 2007 Run some decent injector cleaner through it and i would reccomend replacing the lift pump after feeling the difference a new one made to my disco Quote Link to comment Share on other sites More sharing options...

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. Foxminer.

WALRO Posted July 15, 2007 Author Share Posted July 15, 2007 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.

JimAttrill Posted July 21, 2007 Share Posted July 21, 2007 Black gunge in the inlet after the intercooler could be the EGR, if you haven't already removed it. Quote Link to comment Share on other sites More sharing options...
