2005 X5 4.4 White Smoke

Hello All!

New to the forum and BMW. My wife's 05 has been great with the exception of the following issue. A while back I started noticing a white smoke after sitting idling for a few minutes at traffic lights, etc. I found this forum and all of the great advice and quickly found the passenger side CCV torn. I replaced both sides as a precaution and inspected the hoses as well. I have run two tanks of gas through the car along with injection cleaner but still have the smoke.

Please help! Rob

you can remove the intake hose from the throttle housing to look inside the manifold for oil which can remain in there for a long time after replacing the ccv .

Wait what? I have the same problem but what do i need to do to fix it? Can it be the oil separator valve? and whats CCV?

amacman - I wasn't sure if I was just being impatient about it clearing out or if something else was going on? I actually saw a post (might have been one of yours) with that same pic and I did look. I still have oil in there, I just didn't think it was enough to sustain the problem? When I picked up my parts from the dealer they also mentioned that they have a procedure and equipment to clean up after this problem....makes sense!

pezho485 - I found with my vehicle (N62 engine) it does not have the dreaded oil separator valve that many have problems with. The crankcase vent valves (ccv) seem to fail quite a bit and is a classic cause for the white smoke. They are inexpensive and very easy to change. My issue was an obvious tear but I was puzzled as to why the change didn't seem to help. Looks like I need to do a little cleaning or be more patient!

I will post some pictures later today to better illustrate for you or you can search for "white smoke" as I did and you will find all kinds of great guidance!

Great place to learn!
