Title: V6 overheating
Post by: jules on 08 October 2009, 14:55:35

Some advice please.

3 litre V6 overheating and plumes of white smoke from exhaust.

No oil in water.
Smell of petrol in expansion tank.
System is pressurising.

Is this symptomatic of a HBV fault or something else ?

Cheers

Jules

Classic symptoms of head gasket failure (combustion chamber to water passage)

Sorry :(

Yep I agree, to be 100% certain, you can get one of those chemical testers. (re-active liquid in a bulb stuck in expansion tank, reacts to exhaust gasses).
