Hey everybod,

I had P2188 CEL pop up recently on my 2009 Mini Cooper S and I'm thinking it has something to do with my PCV hose or my valve cover.

When I lift my hood I can hear air escaping from the area where the PCV hose connects to the valve cover. I don't see any visible oil leaks or cracks around the valve cover. I can sometime smell gas when I am driving as well.

I'm prepared to replace both the PCV hose and the valve cover, but I would like to pinpoint my problem a little better. Is there any tricks I can do to hunt down the source of the air leak? Any help or suggestions would be greatly appreciated.

Sorry, I can't help with troubleshooting ---

Best of luck

 

Thanks for your reply. Upon closer expectation it seems that the air leak is coming from somewhere around the first ignition coil on the left. I removed the coil and expected the area for cracks but did not see anything.

I believe it could just be the valve cover gasket, but I am not certain, and I'm thinking I should just replace the valve cover. Does any one have any thoughts on this?
