Im new to this site thought id see if any of you could help me out with this irratating problem?....
At high rpm, my wrx seems to squeal/screech intermittently. sounds like a loose bolt or something grinding. thats the only way i can explain it. It comes and goes.
I have thought it might be a boost leak, but it doesnt feel like its loosing boost.
maybe its a loose alternator belt?...
The car has recently had: new cambelt, tentioners idlers, water pump, hoses, head gasket replaced, fuel pump and a new clutch. Mielage is 163,000km
help would be appreciated thanks
