I'm trying to get a handle on the parts that are typically replaced during a CCV system overhaul as per this thread (see post #4):
- How to test the BMW E39 pressure-controlled crankcase ventilation system (CCV)?

I'm also confused about the part number for the M54 guide tube as per this thread (see post #29):
- E39 (1997 - 2003) > CCV replacement tips

Q1: Is this the right list of parts that are needed for the M54?

Total $220 to $235 for the following 7 to 8 items:
  1. Pressure regulating valve (cold weather version, 11617533400 = $66)
  2. Vent pipe (cold weather version, 11617533398 = $28)
  3. Connecting line (cold weather version, 11617533399 = $34)
  4. Vent hose (cold weather version, 11157532629 = $15)
  5. Return pipe (stock version is already insulated, 11617504536 = $34)
  6. Dipstick guide tube (redesigned version sans concentric rings, 11437531258 = $41)
  7. Dipstick guide tube lower o-ring (19.5x3mm, 11431740045 = $2)
  8. Vacuum hose black (not on all E39s = $15, e.g., not on the M54)
