The head gaskets were replaced on this vehicle a little over a yr ago. He replaced all the gaskets and o-rings from there up except the pcv o-ring so I now have the upper intake off again to clean the oil out. I need to know the propped torque seq. and torque for the upper intake manifold. It is the 3800 series 2.
