2 things.
you are saying the force exerted by your hand on the VC will be greater than the pressure required to BLOW APART the cast aluminum valve cover. And, that the VC has
the weakest seal on the engine. I find both of these very difficult to believe, please explain.
2nd- do you think that the absence of a postive crankcase ventilation system would cause harm to an engine? Lets say the the crankcase pressure only had to overcome atmospheric pressure at all times.
