Turbo whistle

**bigmarkc** · 18th October 2012, 10:29 AM

I have a yr 2000 GU with a ZD30 DI which has developed a whistle from the turbo.More noticeable when cold and seems to only have a slight whistle when warmed up.Doesn't seem to affect power though.I wonder if a scan for fault code would show any problems ?

the battery for an hour,

I should say that its a loud whistle which turn heads from pedestrians.

Leak from somewhere? Possibly intercooler?

The turbo should or shouldn't have the whistle as it were ... if it "develops" a whistle, I'd suggest it's the manifold leaking, or the bush in the turbo (if not a bearing type). Nothing dramatic, but would be running a spanner over some things - I developed a louder than normal whistle on mine (which I didn't mind actually!! lol), but it turned out to be the back two bolts of the manifold being loose ...

yep you may have developed a boost leak, check your pipes, intercooler (especially) and manifold

My work car is the exact year as yours and exact problem. Ended up being the intercooler the first time and now its come back again.

Havent had a chance yet but I'll check mine this weekend. Stops after warming up but more noticeable when cold too.

Will check...Thanks

Being that its more noticeable when cold says to me its an exhaust leak. As the engine warms up everything expands which will close up the gap making it less noticeable once warm. Im with everyone else have a good look for an exhaust or boost leak somewhere.

yea id look at the exhaust manifold mine did the same thing and had to machine it, mind you this was before its 20k service and was done under warranty but check it out id put $ on that
