To preface this I only have a CAI and JB4 chip and some suspension mods. The car only has about 70k miles and is a 2011 S. Both my S's (convertible 09 s and 2011 s) had rebuilds because of cyl 4 failure. both had the same high pressure fuel pump failure at 70k Otherwise pristine except its lack of back seats.

My problem is the car had a serious oil leak from the plastic valve cover (where the oil catch can connects to PVC) and from the oil cooler. Right after I discovered this because of the oil spraying on the turbo and a huge plume of smoke out my hood scoop my A/C compressor siezed.

Is this related? I heard some bmw cars shut off aux systems when certain codes are present. I can get codes just lazy.

Secondly, if someone has experienced this please let me know what repairs are needed. Also, how bad is this going to hurt my wallet. I like standing on my wallet because it makes me taller.

 

I would start with a new valve cover. OEM Mini is preferred, but costly.

Then, clean up the oil spray really good to make sure you find exactly where its coming from, then attack that.
