right well on coldstartups i get this noise its hard to describe kind of like a sqealing noise initially whilst it starts then if you rev it for the first minute or two whilst it warms up it does it then aswell, i thought it was alternator belt or pulley at first which was replaced today and still makes it only on cold startups when it is warm no problems at all boost fines etc, the only thing i can think of is cracked ths exhaust mani as i imagine it would close when hot? any ideas? or anyone experienced this before?
