Burning oil with a turbo setup

[Johnny-Five]

Hi guys,

Need some advice off anyone with good turbo knowledge.

Right, problem I have is on boost the car seems to be burning oil... but not all the time. It also occasionally kicks some out when it's been stood for a few days... but this is quite rare.

The engine is sound, checked the turbo and this also seems fine... where else could oil be getting into the system?

The car has an oil cooler and intercooler fitted.

Starting to do my nut in...

Have you done a compression test? Could be worn valve stems...

[Johnny-Five]

Yeah done all that and the engine itself is really healthy...

Usual suspects -

Turbo seals
Valve seals
Piston rings
PCV valve
