first thing i noticed was the turbo was almost siezed. so it came apart last night and there was huge carbon build up behind the exhaust turbine( a solid coke washer!) and the inlet was totally drenched in oil. the inlet bush looks ok and so does the shaft but i cant get the circlip out of exhaust side to inspect bush. reassembled loosly and turbo spins freely as it should. so is it just that previous owner was 104 and never went boosting, or is there usually a deeper reason.
alsowhat else is worth checking on these engines? any usual suspects??
