W201 Crankcase Ventilation
I have some oil present on my engine around the valve cover gasket and around the crankcase ventilation lines. While investigating this, I found that if I remove the oil filler cap with the car at idle, oil "spatters" out of the filler hole. Shouldn't there be vacuum present that prevents this?
Further investigation revealed an electrical component that appears to be part of the crankcase ventilation system. It is positioned between the intake ports of cylinders 3 & 4.
So I have 3 questions:
1) How does the crankcase ventilation system work on this car?
2) Is mine working properly?
3) What is that electical component?
Thanks in advance for any insight you can offer.
