Won't be the first time we've found a defective N54 cover. I also bought a digital manometer to check the PCV and crankcase pressure.
Actually, my mechanic pointed out to me not to place my hand on the valve cover when leaning over the engine as it is not designed to carry body weight and can crack easily.

He suggested placing your hand on the oil cover cap as it is supported by the block underneath.

The valve cover.....not so much.
