Take off the pipe between the inlet manifold and the intercooler, check for signs of oil. If there is excessive amounts present then that is an indication the turbo oil seal has gone, as said remove the induction pipe running from the turbo to the intercooler and check for play in the compressor turbine, if you have excessive movement the that is normally enough to condem the turbo.


If this is the problem a few points on refitting:

Renew all seals/gaskets
Prime the turbo prior to fitting of the oil inlet pipe (a syringe is best to add the oil)
Clean out all the pipes, inlet manifold and intercooler as they will probably be soaked in oil.

Finaly to keep your turbo in good condition don't for get run up and run down procedures, ie leave it for a few mins on idle prior to driving and a few mins on idle prior to switching off.

Hope this helps.

Describe excessive oil in the turbo to intercooler pipe. I cleaned mine on 120k and it was evenly wet.

Don't mean to be rude, but this topic is of interest to me, and I can't help but thinking some punctuation in dorsetsmith's post would greatly improve the context of it, and be far more helpful. I've tried re-reading that post a number of times to try and work out what is being said, and it makes very little sense. I'm sure we're both grateful for the help, but it is not easy to understand when it is just a collection of words.
