Hey I am trying to diagnose an oil leak on the back of the engine, it is not the turbo, valve cover, and doesn't appear to be head gasket. I cleaned it all up and wiped down to as clean as possible, no significant oil present, then started it up and let it present again. The only place I can see it coming from is the engine mount on the pulley side of the engine. it runs down the back side then down the block. I cannot think of something that should leak here. There is no oil in the timing cover or on the belt as I can see. I have recently used a engine mount bracket repair kit on it purchased from idparts. Any ideas of what might leak??????
