I have learned that if you drive gently and try to stay below 2k rpms the car will drive fine.
I drove like this after the most recent time the ccv froze. The x5 ran fine no smoke or anything.
This morning i thouhgt i would test my theory so I bump the gas twice so the rpms would go above 2k quickly... sure enough the x5 began to smoke like crazy!! previous times my wife was driving it so i didnt experience the the problem.

This time I was driving, the car was stallling and there was smoke behind me for a 1/4 mile. Not kidding! I couldnt see the cars behind me.

Im guessing the oil is entering the intake and flooding one or more of the cylinders.

Is this a possibility? Im not familiar with the setup. Just wondering if there is a way for a gasket to blow and allow oil to enter the cylinders....?

I just bought this recently, from a single owner who owned it from brand new with 130k. Its in really nice shape. But i dont think my driving style is a good
fit for the car as i dont do long trips just short ones.

In case of M54, the oil gets in to intake via dipstick tube (there's some branch in to the crank ventilation system from a dipstick) - you can bore some holes at the bottom of the dipstick tube to prevent it while the engine's getting warm. But there's a danger that the dipstick should have a connection to the atmoshpere and so the air will also get in after the usual CCV system will work properly - so some oil foam will develope from the oil film covering the bottom of the dip stick tube, but some people report it works. Still I wouldn't do this on my car due to the possible foam developement, which is also very dangerous.
