Hi, as anybody had a high pitch squeal.
It starts only when warmed up, it doesn't go when you rev it but it changes pitch slightly.
It sounds to be on drivers side prob from tubo to Nr coolant tank area.
I fit complete timing belt kit/ water pump and have had both belts back off and run it and squeal is still there.
As anybody had anything like this with the turbo as it does sound like that area.
Once cooled down it goes off.
It's a 2003 wrx.
Also had complete clutch kit, this problem was there before I did clutch.
Many thanks Craig

Has it only occured since changing the belts? Power steering belt might need adjusting making the pump squeal

Not sure if it was there before I did all belts as I didn't run it.
I have both pas and alternator belt off and run it and it's still squeals

It's usually loose belts, but that tends to be worse when it's cold.

Was the power steering pump turning freely?

What of the alternator?

And could it be a tensioner/roller for the cambelt?

Lastly, get the turbo bearings checked.

That's what I'm thinking turbo bearings, I also had stethoscope everywhere but to no avail.

Maybe timing belt rollers possibly then? Try listening by putting a screwdriver to various places and your ear to it,you should be able to narrow down where it's coming from. Could it be the turbo itself whining/squealing it might be knackered. Has the car sat for a while? You said you hadn't run it before changing belts

Yes the car as been off the road, for some time, I bought it off someone who changed the engine due to old one had big hole through block.
I bought it with the problem of it not engaging gears. So I removed engine fit a complete clutch kit/ flywheel skim. Complete timing belt kit with every pulley and new water pump.
I have been round it with a long screwdriver and even a stethoscope but can't tell, but does seem like its coming more from turbo area.
There is no play in the turbo but its starting to sound like it could be the prob.
Thanks for that.

Yes will do cheers

I once had an impreza that had sat for a year and the turbo went on that. It was making a loud electric motor sort of sound

scoobyJim2

Check turbo oil feed is clean if its sat around it could be gunked,not supplying suffice oil. Though I would think the damage is done now if this is the case

Wyorksautoectrical

Thanks I will check that..
