What are the causes of Jaguar XJ turbocharger failure?

[MacAdeline]

Jaguar XJ turbocharger failures can be caused by oil leakage or compressor end oil leakage in the turbocharger. Specific details are as follows: Oil leakage: High oil consumption with normal exhaust color and no power loss; usually caused by oil leakage. Solution: Check the external oil pipes of the engine lubrication system for leaks. Compressor end oil leakage: High oil consumption with blue smoke from the exhaust but no power loss; occurs when oil leaks from the compressor end of the turbocharger and enters the combustion chamber through the engine intake pipe to be burned. If the turbocharger oil return pipe is blocked, excessive oil accumulates at the intermediate support of the rotor assembly and flows along the rotor shaft into the compressor impeller. Solution: Inspect the compressor outlet or engine intake pipe for oil residue on the pipe opening or walls.
