What kind of ventilation does a BMW crankcase have?
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.
How does the crankcase vent work in a car?
When working correctly, oil is removed from the intake air and returned to the oil pan. Oil vapor remains and is burned up in the combustion chamber. 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. The problems are worse on the turbocharged models where the CCV needs to keep up with the pressure from the turbocharger(s).
How does the crankcase vent system work in a BMW?
The BMW crankcase vent system separates liquid oil from the air inside the engine and intake. When working correctly, oil is removed from the intake air and returned to the oil pan. Oil vapor remains and is burned up in the combustion chamber. Every car has some form of crankcase ventilation,…
How do you replace engine plugs on a BMW?
To replace the plugs you MUST first heat the area rather hot. I suggest you do NOT re-use the original slotted type of plug, it is NLA anyway. Be sure plug and associated engine threads are clean and dry, use a strong solvent as required. Use a couple of drops of very strong Loctite on the threads before assembling.
Why is the ball valve open on my BMW airhead?
The oil pump is quite powerful, and there is only so much volume of oil that can, at any particular pressure, flow through the central pipe into the large passageway system…hence my belief that the ball valve could open. This is more likely to be so with cold thick oil and a sudden ‘slug’ of oil from the pump, upon start-up.
Why is the CCV valve on my BMW not working?
The condensate forms inside the CCV valve and mixes with the oil droplets. This creates a dull yellow “gunk” that clogs the valve and prevents it from operating correctly.
