Crankcase vaccum helps pistonrings to seal. It's all good I've been told.
When the engine is not under load the oil vapours will be swallowed by the engine through the hole in the plenum chamber side since is has the lowest pressure of both. The restrictor must be there to control the vacuum effect. Under load the amount of pressure and oil in suspension will be higher and most of it will escape through the non restricted duct (A line) |
