having to add a quart every 700 miles

2006 750 I have found myself having to add a quart every 700 miles. I have replaced the crankcase vent valves both where bad. I have also checked for leaks and none found. I am not seeing any smoke in the mornings at start up. I have also followed my wife and I dont see the car smoking going down the road.
I know its got to be going somewhere but I cant figure out where.

Any ideas?
