So I replaced my PCV Breather / oil filter housing 18k miles ago. I don't know if its the cause but every time I open the hood there is oil on top of the cap and misting in the direction of the passenger. I let the car idle and tried to remove the cap while it as running. There was some pressure pushing up. I've already checked through the PCV brether lines and none are clogged. I've changed my oil every 3-4k miles so I find build up an unlikely suspect anyway.

Any ideas on the cause? I'm stumped


in the mean time the car runs fine i just wipe off the oil from the top every so often

 

Have you checked the oil filler cap itself?
May need a new seal or even a complete cap replacement.

 

I ordered a new one a few days ago. Hopefully that's all it is. What concerned me was the presssure.

 

That would concern me as well. There should not be pressure there.

 

Has this car had its PCV system overhauled as per the recall? Is the riser tube from the oil filter to the cyl. head corrugated or hose? Corrugated is brittle & bad.

The PCV recall replaced far more than just the hose; I believe there was a check valve IN the oil filter housing that was redesigned.

 

The OP replaced the oil filter housing.

 

Yes, to answer the question. I replaced the whole oil filter housing and related hoses 18,000 miles ago. I had ordered the new housing from Ipd in 2013. I don't know what year the recall was?
