There's A Banshee In My Bonnet!

[Lost]

i wish it was more exciting than the title header... but it's not..

I can't seem to get rid of a squeal that seems to be coming from the passenger front of the engine bay. Only happens high in the rev range 4k++ and if I absolutely mash the accelerator.

I thought it was the alternator belt and have since tightened it, this week changed to a new one.

The clutch was slipping and I have got a new one this week.

Any ideas what it can be?

Thanks again!

my guess is an exhaust gas leak from the turbo. I had it when i got a dodgy front pipe put in. replaced it later with a proper dump/front pipe and it all went away.

Cracked/broken exhaust studs or leaking exhaust gasket would be my bet- mine does the same & thats what I found after a bit of investigation

Man SAU Rocks!

Talk about specialised knowledge. I will get it checked out.

in the meantime, what could this mean to the performance?

thanks again.

Try your airconditioner pump tensioner pulley (lowest positioned idler pulley). Mine squeels around 4k and I believe it to be a noisy bearing. Disconnect the the air con pump belt and see if it still squeels, mine stopped when I disconnected the belt. Bet thats what your squeel is!

you want to hope its not a turbo on the way out.....

but id suggest an ex leak as above.

or a power steering pump on the way out..
