    Welcome, thanks for joining Motoring Alliance, the FUN and Friendly MINI Community.

    Can you see where it may be leaking from?

    The valve cover is not torqued to the correct spec and probably torqued in the correct order.

    Correct order, center out , Cylinder head cover to cylinder head 12 nm.

    Welcome to the forum,

    I purchased a 2007 MCS in March and had to replace all timing chain components, after the repair oil started leaking around my coils! Even before I had the timing chain components replaced I was burning a quart of oil every 800 miles, after replacing my valve cover with a new updated one I'm burning no measurable oil.

    My cyclone separator was stuck open (PCV system) inside the valve cover, that's why I was burning oil. Now I'm not burning any measurable oil. It seems like the valve covers (integrated PCV system) start going bad around 50,000 miles, this is where some find out all of a sudden that their starting to burn oil for the first time.
