As above, ive just had to remove the turbo this weekend to put a gasket on the oil return pipe to sump as there wasn't one on there.
Now its all back together I can hear a whistle from the turbo and lack of power ....
The only pipe I noticed that was in very poor condition was the one that goes onto the turbo from the air filter could that be my leak , and can I buy a replacement for this ?

 

Did you replace Up-pipe and downpipe gaskets? I'm pretty sure mine was properly crushed when I last removed the turbo - so it needed a new one.

 

yeah I all so used sealant...
But the pipe that slides onto the inlet side off the turbo was proper knackered...
