Hi all. I've got a new issue with my 93 525i Touring. I'm hearing a whirring noise coming from the engine and it seems to be coming from the head somewhere... It gets higher and lower in pitch with engine speed. If I keep the car in park or neutral it happens as well. Would that eliminate the tranny as a culprit?
I took off all the accessory belts and it's still there. Any ideas on what would cause this? VANOS? Cams? Something else?
