Hi all.
My wife's R56 Cooper S has got some oil leak problem. Sometimes there's a small puddle of oil left in our garage from almost the dead center slightly towards the passenger side of the car.
I thought it was the timing chain cover issue, the dealer inspected it and told me the timing chain part was totally fine. SA told me it was just the PCV system leaking oil.
When I jacked up the car, I found the starter motor covered with oil, it seems like the oil is coming from underneath the intake manifold.
I didn't see any significant sign of oil leak on the timing chain tensioner when I replaced it just for the heck of it, and I do see little oil inside the air charge pipe.
Can a cracked PCV hose cause this kind of oil leak? My old Saab had PCV problem and didn't spit out nearly as much oil as this...
Thanks for your help!

 

There is a PCV hose that runs from the valve cover from the PCV valve to the lower part of the intake manifold. This puts it within the starter location.
