Ok, brains trust time. Megane had the symptom of a bad PCV diaphragm - poor stumbling idle and a massive crankcase vacuum so it was quite hard to pull off the oil cap while running.
Uses the same sort of valve used in a lot of european cars.
New valve, no change. Old valve popped open and put back on with the cover off and the diaphragm is good and gets pulled shut just fine - so its restricting the crankcase vent feed, but still pulling a massive vacuum on the crankcase. wtf?
