E46 N46B20 oil in Intake manifold and maf sensor code

Recommended Posts

Hi

I have recently been getting maf sensor code and consequently can torque interface 82

I've checked for Vacuum leaks and found  a small one to fuel filter, fixed and made no difference

Then went and replaced the MAF and still comes up with the code so I took the inlet manifold out to check today and found so much oil dripping out of it, cleaned it as much as I could

CCV seems to be the only place that can cause this,  being a suspect but My ccv is relatively new as well as all the hoses, checking the oil filler cap while engine is running and I do get a slight Vacuum 

 

Maf error only comes up after the engine is warm and been running for more than 20 min but then it would stay for the rest of the day

Anyone can shed some light on this? 

Thanks
