4.4i? Probably same issue. e38 it was the Vanos...easy to check and repair..Mine was torn first. Little smoke, bad accelleration. Then it ripped all the way through - lots of white smoke, no accelleration (unless floored)..Bought a E53 and the CV hoses were completely destroyed and fell apart. No white smoke though. I was loosing oil and couldn't figure out where. Come to find out it was going airbourne via the hoses..
