hi there

i have recently bought a 1999 evo6 gsr and when i picked up the car i noticed a whining/squealing noise over 5krpm under full load in every gear.

i sprayed some wd40 on the aux belt and it goes away for a few minutes but comes back again it dont do it in neutral.

ive changed the belt, tensioner and idler and still there.

the water pump was changed just before i bought the car (prob cus of this noise) it has the a/c pump, p.a.s pump, dampened crank pulley and alternator left to change, theres no play or roughnes in any of the bearings and ok at low revs.

hepl please anyone :confused:

Is it like a whitsle, or rubbing whine.

Becuase if it sounds like a whistle, then it is the blowoff valve for the turbo.
