noise = bad.......

g'day guys,

i have a little concern about my R33. whenever my turbo comes on boost, it squeals to high heaven. nobody seems to know quite what it is. i've heard some say that its a boost leak or something from the turbo seals, but the car hasn't lost any power. am installing a boost gauge shortly, so i'll see where its boosting. got me stumped. its gradually been getting worse over the past few weeks. i dont drive my car particularly hard, but i kinda have a feeling its time for a new turbo. any ideas would be great.

cheers.

Check your exhaust manifold gaskets and turbo gaskets. They may be leaking.

Here's one from left field, but when my clutch fan seized, the belt was slipping at high engine RPM... but you should have heard all the excess air being blown at the engine... it's pretty loud.

can also mean a stuffed turbo bearing... But that has an added grinding noise.

But on rare instances.

ok, so installed to boost gauge on the weekend to see if its leaking, and its not. its running at spot on 7psi. doesnt roll back, it just sits a dead on 7psi. so, i took off the bov to check it all out. the gasket is a thin metal one, so im thinking of changing that. but its not leaking any boost, so this is leading me to believe that it may be an exhaust bolt or something else. am yet to check the turbo, but will try to do it soon. work is flat out atm. hhhmmmmmmm.....dont know what else to do.
