Hi guys and girls 1 quick question for you. I blew the diff on my jetta vr and im thinking of getting the flywheel lightend while the gearbox is out. Is it recommended and if so how much can you lighten a vr6 flywheel without it giving any running trouble? and also has anyone had trouble with blue smoke when on overrun down hill? If so what is the cure? Valve stem oil seals? All help greatly appreciated many thanks shaggy
