Bentley Manual Reference for CCV?

Can't find a word in the manual about CCV. Is it not covered or do I not know where to look? Have read DIYs about changing CCV components and how difficult access is. Wondering if it would be worth the trouble to remove my intake manifold to avoid aggravation while creating more work?

There is no need to remove the intake to make this job happen--just a lot of added work. I do recomend thought that you do this job the way I will discribe. Buy the new Besian Vanos seals and a new valve cover gasket--along with a new oil filter housing gasket and the cvv and the 4 hoses that go with it.
Now dot the Vanos seal change along with the oil filter housing gasket--before replacing the filter gasket
do the ccv job while you have the oil housing out of the way and can get to everything with ease--you will still need to remove the air intake system and all -along with the throttlebody and electrical junction box thats located nearby--doing the job this way gets you into the tight spots with ease--will take about the same time as removing the intake, but this will be easy compared to removing the intake and fuel injection and all.
Along with that , you will benifit for replacing parts that will be ready to be replaced anyway and added performance is another point--if you haven't replaced the cooling system--this would be a good time to do that job as well--if you do all the above with the cooling system--a good sat and sunday job --easy wrenching

You're right, Bentley has nothing on replacing the CCV. Here's the CCV DIY for an M54:

Thanks for the replies. I do plan to do all the DIYs mentioned as one big project once the weather warms up. Two weeks ago replaced my radiator which sprung a pin-hole leak in the classic spot on the upper hose spout. Also will pull bumper and headlights to get at my aux fan which runs ok, but draws current from my battery all day and all night when the car should be "asleep."
