<< < (2/3) > >>

bambamjj:
Cleaned out the intercooler with paraffin over the weekend, whilst it was soaking i noticed a very slight leak of parrafin from th fins once it had been soaking for a while, could this be the cause of the whistle?

stuvy:
can you Youtube the noise with a short drive?

as for the rad i would have said no unless the system is completely dry???

would be a suspect if you ask me.. increased boost forces more air out from thetiniest of holes. get someone to rev it while yu feel for drafts under the bonet.  could also be something along the transmission, as increased power brngs increased stress on componants.

difficult to say wiithout seeing/hearing it tho

bambamjj:
on way home tonight i can drive sensibly but if i push it hard then the noise appears until i back of throttle, reckon it is piping/turbo related, how can/what do i look for to inspect the trubo, ideally while in situ in the car.  Gonna try and get some new hoses, not worried about silicone.

your help is very much appreciated.

As for youtube i can just about run to using this forum

lee celtic:
If it is engine related you would hear it sat still while reving ...

If it's only heard while moving I'd say transmission ,ie. a dry joint on the props or no oil in one of the gearboxes or diffs:shock:

And I know this is a long shot but a mate had a crisp packet get sucked into his wing and lodge next to the air intake trumpet inside the wing it used to flap so fast under load it sounded like a fox screaming took him ages to find it.. :lol:
