It's not a skyline, its my 20tone digger which I use for moving dirt.
Im learning how to fix, rebuild etc with the engine it has so I've got practise instead of braking an RB engine.

Anyways its a 6Litre turbo an I mean hench turbo.
I warm it up and cool it down like I would a skyline but ive noticed when I turn it off it makes a short screech. To me this sounds like the turbo fan stopping when they should spin for a while.
Its leaking oil aswell :mad:

When the engine is cutt off it cuts the oil supply to the turbo and thats why I think its the turbo? am I right? :blahblah:

when u kill the motor, does this noise sound a bit repetitive, i.e the impeller blades hitting the comp housing? This sounds very similar when my GT4 tubby had failed...
What happened with your GT4 ?

No I think its one short screech soon as the engine cuts out. Sounds like metal to metal. :confused:
