The PCV valve is hidden by intake manifold and engine bay wall/wheel well and P/S pump. I want to cut a hole through the wheel well into the engine bay to access the pcv valve but am concerned this will compromise structural integrity of the engine bay. The hole would be 2-3 inches in diameter to pull off the hose and change out the valve. Would drilling this size hole compromise engine bay structural integrity?
