Sorry for not explaining it was the PCv pipe on the driver side that was cracked and the loss of oil was due to a crack in the pipe I was adding a court every couple of hundred miles now that he's replaced and all should be good the machine shop gave the bill of health for the valve guides but the valve seals were bad .

I also have an 09' JCW just an R55 instead. Around 60k miles I started having oil consumption issues and mine is pretty bad (in my opinion, then again never had a car that used oil this bad...). I sometimes lose about a quart between re-fueling the tank and then sometimes I can go longer before (possible two tanks of fuel or more)I have to top it back off. So there seems to be no consistency in the amount/time frame that it goes through oil.
Things Ive had checked:
Pressure test on valve cover
Updated valve cover installed around 30K miles
Walnut blasting
Zero oil leaks (at one point the oil feed line and gasket for the HPFP was leaking)
No coolant/oil mixing
Odd thing is that I never see any type of smoke except at higher rpms my car will puff out a cloud of black smoke with spirited driving. Never at idle.
Im kind of stumped on the issue. A MINI tech friend and my regular mechanic has suggested a turbo replacement and adding an Oil catch can. If that doesn't work then head job. I wish I didn't enjoy this car so much, otherwise Id dump the thing even thought it has been pretty reliable other than this issue.

Let me know if I can help.

Back on the subject again:
Had a compression and leak down test performed - well within spec
Smoke test - no leaks
Pressure tested between the turbo outlet and Throttle body inlet - hold 25 psi
Developed a CEL - P1497 that I have been chasing lately
Replaced a bunch of stuff - shotgun method (have a bunch of spares now)
Valve cover - 11127646555
Oil ring for Camshaft position sensor - 13627567572
Fuel tank breather valve - 13537543285
Gas cap - 16117222391
Vacuum tank - 11657560916
Vacuum lines - 11657570465
Pressure converter - 11657599547
Diverter valve – 11657593273
Intake manifold gaskets - 11617528340, 11617528341, and 13627567571
Intake hoses - 13712753077 and 13712753078
Decided to remove the PCV Delete (PCV hose delete with proper plugs on both ports) and put the hose back on. Guess what..... CEL P1497 is gone.
So I added a second catch can on my JCW MINI.
Still burning oil though.
Could it be that the pressure was building in the crankcase causing the CEL P1497?
