TECH-INFO: Cylinder head cover valves, engine management

Discover the difference between valves in our practical TECH-INFO, Crankcase vents with and without diaphragm valve. The necessity of the motor code is also explained.

Problem

  • Too much vacuum in the crankcase system prevents the right oil flow

Reasons for failure

  • Using the wrong oil separator

Recommended by the experts

  • Please check carefully which oil separator is needed
  • Use VAICO Experts Kits +: cylinder head cover + oil separator, for detais see page 2

Did you know?

Cars with engine code BPY, BWA, BPY, BXIK have enough self pressure in the pressure room. For those cars it is absolutely necessary to use the oil separator without throttle valve (06F 129 101 P, V10-9751). Otherwise the pressure is additionally increased, which leads to too much vacuum and further issues to the breather system.
