i took the head and everything off my supra to put a MHG on and also put new cams in. now the car has a occasional drip of oil that goes onto the exhaust manifold then burns off. its driving me nuts. the drip is directly under the bolt that holds in the cps.its coming from somewhere aorund there.. does anyone have an idea fo what it could be?. i put new cam cover seals and everything on it.
