Just been contemplating crankcase ventilation and how it works in the non turbo FSI engines.
As far as I can determine the crankcase is kept under a constant vacuum by the operation of the PCV valve in the rocker cover.
Does anyone have any idea what the amount of vacuum actually should be. ( I’d measure it myself but my daughters golf has a broken diaphragm. )
