missis classic wrx has developed a engine noise, its a my94 and the noise is a whiishing that changes with revs, like a shhhhhhhhhhhhhhhhh if you get me lol, Ive took alt and a/c belts off and still does it, sounds to be comin from the passenger side either the cam pulley area (gonna wip cover off when it stops rainin) maybe futher back slightly but deffo front or side of passanger engine, any ideas? deffo not a grinding,knocking etc

anyone?

noises are hard to diag without the car but post a youtube clip and we eill give you a better try
