Hello everybody. I have just noticed a high pitched whistle which changes tone with the engine. It seems to happen a while after start up. I have not been on a long enough drive yet to see when if at all it disappears. It seems to be intermittant. I thought maybe head gasket as it does sound a little like that gas escaping sound. And it does change tone with operation of throttle. Anyone got any ideas??

A mates discovery did this and it was his alternator,
It could be a idler pulley too.
Always a drag.

Sounds like warped exhaust manifold.A search on here will help,heaps of info on this issue.
check for broken exhaust manifold studs on number1 and 5 cylinders,have just discover mine with the same problem.common problem when a lot of towing is being done
This is a td5 problem,not a v8 problem though

Ummm,that changes things....
One of our work vans on LPG also does this from time to time,doesn't seen to affect anything.I recon it is a leak on the inlet manifold or associated pipework somewhere,it actually sounds like a turbo wastegate whistle.
