possible turbo problem? - willJspears - 22-11-2013
what are the first signs of a turbo going bang? its just that ive got a strange noise coming from the engine. it sounds like a light metal on metal rubbing sound and gets louder when engine is revved. it only started happening after i straightened out the exhaust (where middle section connects to cat). not sure if its the turbo or if its the fan belt as shes starting to get a bit squeaky on start up. any ideas?

Could be the aux belt tensioner? They're fairly common to fail.

See if it squeaks with the cd player, blower, all your lights and the heated rear screen on.

The turbo usually has a slight delay after revving it as it needs to be spooled up, so if it's immediate then it's not likely the turbo.

with a decat and clearer exhaust i bet you can just hear the turbo more

Yeah, I can hear the turbo more, but it just seems to be a different noise to what is sounded like before. But since posting this thread it seems to have settled down now. So I'm not to sure really.
