Ok, noise back with a vengance!
Really odd one this, seems to come on with boost but on the odd occasion have heard it just after starting up and pulling away around 1500rpm. but tends to go away pretty quickly and only comes back when on boost!
Stripped the pipework off around turbos and intercooler and there seemed to be quite a bit of oil in them, but not much play in the shafts of the turbos about 1-1.5mm some oil in turbos too.
Also checked the breather pipe between cam covers and no oil at all!
Dont want to pull the turbos off and replace incase its not them thats knackered!
Please help!
Cheers
Sean
