2017年4月12日 · My 91 325i with an m20 is suffering from a PCV issue. I have negative crank case pressure (vacuum on oil cap). The idle is good with the hose plugged, and the valve cover open to atmosphere. I was looking for options to delete the PCV, some sources called it a CCV.

Every car has some form of crankcase ventilation, also known as a PCV, CCV, oil separator, and a cyclonic separator. BMW CCV system are notoriously failure prone, leading to high oil consumption, burning oil, loss of power, misfiring, and high carbon deposits.

2013年3月27日 · I'm used to just reading about moving pcv valves. I also kept thinking guys deleted the oil return tube/pcv tube on the drivers side that goes from the block to intake mani.

2009年8月10日 · To the left of the throttle body there is the icv inlet and the positive crankcase ventilation (pcv) tube. You may also notice two smaller tubes going to the same spot as the pcv. These are coolant lines, to cool the crankcase air. The pcv tube runs under the intake manifold and is somewhat of a bitch to change. Okay so far so good.

2009年8月11日 · The most common ones to go bad on the m20 are- pcv tube brake booster vacuum gauge line And what i believe to be the fuel tank vent valve line, which runs from the charcoal canister to the bottom of the throttle body. Its very difficult to see without removing the intake boot, but there is a rubber elbow there and they tend to crack through easily.

2019年5月12日 · On the m20 the entire crank case is part of the vacuum system (you'd think this would help with the oil leaks!). Maybe it is the same on the e30 m42 (since there is no PCV listed), but on your particular engine something hasn't been installed correctly and the crank case is actually sealed up, and thus it is over pressurising due to blow by.
