Hey CN, thanks for doing this. I am collecting parts to do a whole punch of stuff on my MT as well. I plan on moving it into the garage and take as long as it takes to change all of this stuff and your write up is going to help a lot. Especially all of the small little tips you share during some of the steps. I am a noob when it comes to this stuff so I will probably replace the battery anyway so it looks like I get to remove the battery to do this.

Thanx CN, I appreciate the tutorial and this is brilliant work! thanx again!

Update...

- I have since decommissioned the CCV and used the "BavarianE39 CCV Mod", the mod works great...

- I forgot to post the ICV tricks, just did it now, there are some tricks...

1. At 17 yrs/140K, the rubber boot cracked. Happened to see the cracks during routine inspection. No CEL codes at all.

2. The "impossible Rubber Boot screws facing downward".
- No problem, use a Black Sharpie and mark the end of the screw so you know it is turning.
- Use a pair of right-angle pliers and turn the screw, since you are facing the other way, in order to undo the screw, you need to turn it clockwise from where you are standing. This is like turning it CCW if you face the screw.
- After a few turns, tug it and ROTATE the screw upward. Life will be 100x easier now.
- The rubber grommet: at 140K, it looks good, you can re-use it.
I happened to buy a new BMW grommet, so I installed the new grommet.

- Rubber Boot ~ $25 at dealer
- Rubber Grommet ~$23 at dealer (this part is optional). I think this part will last some 20 yrs/200K+. So again, re-use it if you want to.

That is all...
