Hello everyone. I've owned a few BMW's over the years and I love 'em. I initially searched the web for a solution to the 4.4 smoking issue and saw that it is usually the valve covers or the CCV's or both.

Mine has 120k on it but is a great vehicle aside from the smokes after idle when warm issue.

It led me here and I signed up to be a member- but I can't find the thorough thread that gives tips on the easy way to change the CCV's. I found them on Fleabay for around 25 usd each.

Could someone link me to that thread as I know this has been discussed before.
Thanks and I'll post pics of my 06 soon.

You may want to consider that the 2004-2006 v8s and some thereafter had faulty valve seals which is a well known common problem of the X5s. You can change the CCV first but many of them have the valve stem seal problem that is the cause of the smoking. The replacement ones are of much better quality than the originals that BMW used.

And even then it isn't much. 120K is not what we consider "high miles" ;) We've got some with 270 on 'em. I saw the valve cover video and this guy's was different, so I wanted to make sure before I hit the "buy it now" button twice.
I'll probably take the valve covers off and clean them out, do all the hoses, plugs, tensioner and the belt while I'm in there. If I ever need to pull the heads, I'd pull the whole engine and put it on a stand. These cars are cheap enough, if this doesn't do it, I'll drive it until the tires need replacing and sell it dirt cheap on CL. :)

I'll post pics and updates on this thread when I tear it apart in a week or two. :)

Normally I would agree with you on this but its known that the original valve stem seals of the N62 engine were inferior quality as to what BMW would normally use. They took a cost cut in material quality that ended up being the problem of the owner of the X5 beyond the warranty period. The originals are defective and the new ones from BMW are far superior in material and design.

Not sure if I added the picture correctly, but if it appears, see the 3 dark red-brownish tabs at bottom of valve cover. Simply remove the screws and tabs.

This is classic sign of of bad valve stem seals. On mine, the engine was using 1qt/250 miles of oil - every fill basically. Had below 100 k miles.

Here's a link to a thread.

Luckly I found a shop that did the seal replacement with the aga tool that allowed him to do the job without removing the cams or heads. not cheap around 1600.00. if i had the tool and the time probably just the seals and valve cover seals.

I'm in SoCal also...do you positing or PM'ing the name of the shop you used to do this?
