CCV replacement without removing intake? M54

[oldskewel]

Not exactly what you asked for, but:

this guy 50sKid makes great videos. I followed his series when I did the top end rebuild on my M54. Here is his video for the CCV system:

And another thing you didn't exactly ask for:
It is possible to lift the intake manifold up out of the way without disconnecting a lot of things. E.g., the fuel system is untouched, most of the electrical connections remain connected, etc. I figured this out when doing my M54 engine work, and used it when I had to get back in there due to leaking o-rings on the coolant pipes (that I had replaced with new). Let me know if you want details.

Knowing what I know, if I had to do it, I'd watch that video for familiarization, and then do a partial intake manifold lift out as described, to get full easy access to all CCV components.

EDIT - Thinking more, I guess that depends on how good/clean/leak-free the rest of your intake is. In my case, everything had already been fully removed, cleaned spotless or replaced with new. If yours is due for replacing gaskets, fixing cracking vacuum hoses, etc., may as well take the full intake manifold off, cleaning fuel injectors, replacing o-rings, etc. If that does not sound like fun, then back to my prior recommendation.
