Both the CCV and catch can solutions exist because all engines’ crankcase emit oily vapors. Years ago that oily vapor was merely dumped into the atmosphere. 1. Oil leaks. Oil leaks are one of the symptoms most commonly associated with a bad crankcase vent filter. The crankcase filter simply filters the blow by gases to make sure that they are clean before they are rerouted back into the vehicle’s intake manifold. Over time, the filter can get dirty and restrict the air flow, and therefore There is a unique thread today on temporarily BYPASSING the CCV, for reasons that are up to the owner, but one of which can be to TEST whether the smoke or other symptoms are due to the CCV: > E39 (1997 - 2003) > PCV Crankcase Vent Valve Temporary Installations CCV Component Kit (with cold weather hoses): http://amzn.to/2E6fr65Hose Separator Pliers: http://amzn.to/2GBiTUiDipstick Tube O-Ring: 11431740045My mailing a Amazon.com: Crankcase Ventilation Valve Oil Separator Hose Compatible with BMW E46 E60 E39 X3 X5 320i, 323i, 325, 325i 328i, 330i, 525i, 528i CCV PCV Valve Ventilation Separator 5 Piece Value Kit 11611432559 : Automotive E46 Fanatics Forum is an independent BMW enthusiast website owned and operated by VerticalScope, Inc.

OP is is adding 1 Quart in every 280 miles, that's plenty of fresh oil. It takes a huge oil leak to lose that much. Comes out for me at £87.58. This is for a 2005 320ci (e46) M54 engine, as far as i can tell all the parts are the same through the range and they also work for the M54 engines <2002 the only thing different with the M52 engine is the throttle body was revised so the gasket is different. As always if you are going to use the part numbers above A properly functioning pressure control valve is designed to maintain a slight vacuum (approx. 10-15 mbar) in the crankcase, which assures reliable crankcase venting during all engine operating conditions. A malfunctioning crankcase ventilation valve may cause the following complaints: ***8226; Engine runs rough The valve itself rarely fails. Instead, it is the PCV valve’s filter that tends to impede the function of the valve. The filter is an essential part of the PCV valve, as it catches the majority of the toxins in the blow-by gases. Over time, however, the filter can become clogged. The PCV valve filter should be replaced after every 60,000 This sensor measures the volume of air that is entering the cylinder of your car. Upon becoming faulty, it might let too much air into the cylinder. As a result, the fuel mixture will become too lean, which will be detected by the ECM, and then the P0174 code will pop up. Besides the MAF sensor being faulty, this issue could also be caused if I want to delete my ccv, for that have bought a catch oil but i don't know not as put it, i think that there are have three options: 1) To make it practically equal, the engine will keep on inhaling dirty and warm air. I don't like. 2) with the same system that 1) but putting a catch oil with air filter. The gases are slightly cleaner and cold.
