Thanks for the feed back guys. Pulled the turbo off this morning before work then pulled it apart at smoko. And it looks like you all get straight A\'s because the turbo is definitely stuffed, the bearing was completely collapsed inside. Does anyone know if it is possible to rebuild one of these, seeing as its a roller bearing core? (Ive heard that only journal cores can be rebuilt) And if you can where would I go looking for a rebuild kit? Would also need a new turbine shaft and compressor impeller. Cheers, Mike

I need a little help diagnosing an issue I have. Quick rundown - Version 8 EJ (rebuilt) with VF22 controlled by A\'Pexi AVCR and Link G4 The other day I was driving around a strange rattling noise started intermittantly coming from the turbo area. When the noise was happening it would not build boost, vacuum would drop right up to 0.00psi and then just sit there. But it wasn\'t all the time eg. take off and put my foot down - boosting fine, change into second and and boot it again - strange rattling sound and slowly climb the revs with no boost, change up into third and it would be boosting hard like nothing had happened. Then after a bit of driving, all of a sudden it starts pouring white smoke out of the exhaust, and I mean pouring! I could hardly see the cars behind me. The next day when I started it up it seemed fine but as soon as it was warm, out came the white smoke again. The coolant was very low when I checked so it must be that which is burning, but from where. A google search tells me its either a blown head gasket/cracked head or a rooted turbo. Im thinking that the boosting problem and the smoke are related and that the turbo is at fault Has anyone experienced anything similar ? A mechanic friend of mine reckons its the turbo and I really do hope he is right. Let me know if anyone has any insights. Cheers, Mike.
