If that was my X...I agree with upallnight and would check the CCV...your video looks like the classic failed membrane/diaphragm that tears/rips and allows oil to be sucked in to the intake...which then results in the oily smoke from the exhaust you see in the video you posted.

The video upallnight posted was for the N62 engine...which has 2 membranes on each cylinder head..which is also very easy to access since they are on top. But your X5 has the m62TU engine...and the CCV on that engine is located on the back of the engine...and is a bit more difficult to tackle.

Edwin (e38 owner from the Netherlands) who is an excellent DIY'er has a video up on youtube that shows how to simplify the CCV DIY job on the M60/M62/M62TU engines...take a look and also do the test with the oil dip stick & tube to see if you can hear the gurggling and feel the sucking from the tube:



...the CCV (on the m60/m62/m62tu) is #2 in the diagram below & part nbr is at this link: http://www.realoem.com/bmw/showparts...81&hg=11&fg=40
