axgordon, interested now to hear about the shop owner's opinion on the piston rings. He believed that replacing piston rings on stock CCV setup on M54 would solve oil consumption in higher mileage vehicles? Or alternatively you could keep the low tension piston rings and do the "CCV Bypass/PCV install" like you have done and solve the same issue?

You are correct I just rolled 80k miles a week ago so I'm not as "up there" yet.
