How to replace the valve crankcase membrane/ventilation
I'm trying to replace this membrane:
But the cover doesn't come out. Anyone here made the replacement? What is the trick to take that cover off?
When my car is cold in neutral it is whistling. The noise stops immediately after removing the oil filling cap or the dipstick. I can feel positive pressure coming out when the cap is off. My first shot is replace that membrane.
