BMW gas recirculation valve N52 e90 / e60 / e83 / e70. Principle of operation.

In the video, I tried to clearly demonstrate the general principle of operation of the KRKG (crankcase gas recirculation valve) BMW engine n52, which is integrated into the valve cover.
The function of the crankcase gas recirculation valve is to compensate for excess pressure in the engine crankcase generated by gases that break through the piston rings and valve stem seals, and also compensates for the pressure generated due to oil soaring under the valve cover.
This engine was mainly installed on the E90, E60, X3 E83, X5 E70
