Dear All
I have a 2005 GU 3.0L. Went I am accelerating and the motor is climbing from 1500rpm to 2500rpm I can hear a hissing noise from the general direction of the turbo. Is this normal? I have a mate with a 2000 GU and he says that he does not have the same noise. Could it be that the waste
gate is stuck open? I have checked all the clamps on the intake pipes and through the inter-cooler and found nothing strange. The motor still pulls
well.
Thanks
Angus
