Thread: Hilux making a very odd noise

Started today, noticed when I fired it up after work. If you can get what I'm saying, it sounds kinda like that cliche hot rod sound - I thought something might have been poking into the fan, but i popped the bonnet and cranked the throttle cable and it is definitely coming from the motor/engine bay somewhere. My thought was maybe the start motor isn't fully disengaging from the fly wheel, it has been over starting for a while. It starts and runs fine, performs like normal but constantly has that god awful sound, which speeds up relative to the revs. Hopefully my mechanic mate can come look after work. Any ideas?
