just put rebuilt motor back into 01 zf6 truck and truck runs great and when cold doesnt leak a drop but after it warms up it is a small steady dribble/stream pouring out from rear main area and is not coming down from valley. has anyone ever seen one not leak cold and then leak perfusely after it warms up? if not coming from engine valley i assume the only place is rear crank seal?
