Hi all,
I've had a problem with an intermittent performance on my Jaguar X-Type 2.0 TD Sport 2004 (53). I've checked all of the usual suspects, pipes etc. but to no avail. I took her on a long trip this weekend and now the power has totally gone and my Turbo is squealing like an old kettle over boiling. I don't think my year of Jag has a limp mode as it's the vacuum type with actuator but that is the feeling I get and also there is ALOT of black smoke! I can move the actuator and the turbo impeller spins freely and had no axial movement. Would appreciate anyone's input. Many thanks, Alan.

 

Check for end float by pulling the shaft in and out the thrust beating are gone no doubt and the squealing is the comp wheel rubbing against the housing. Be careful as if it goes altogether the engine could rev itself to destruction on engine oil.

 

Bloody fingers thrust bearings I meant to type of course

 

Thanks Raeturbo,

The turbo is spinning / working as it should. I have now noticed black soot underneath the turbo around the engine. This is obviously where it is leaking from. I am hoping that it could just be a gasket issue. I`m an aircraft engineer so pretty good with tools but not familiar with car engines, how do i remove the turbo / how long should it take?

 

No probs, Sorry but I've never taken one off one of these, but I would imagine there are people on here who have done the job that can help out. The black smoke is due to over fuelling through lack of boost I suspect as the gasses are leaking and not getting to drive the turbine wheel. Also Just to be sure have a look inside your compressor housing with a torch to see if you can see any witness marks of the comp wheel rubbing at the very back. Did you check for end float by the way? Cheers Rae.
