How do you know the diffrence? if it is cold or hot weather version. i did mine less than a year ago and it seen to be going bad again i live in the Bahamas and it is mostly hot here but i don't what version i installed.How did it go?
Did you use the cold weather version?
The cold weather one is encased in a removable relatively smooth foam covering.How do you know the diffrence? if it is cold or hot weather version. i did mine less than a year ago and it seen to be going bad again i live in the Bahamas and it is mostly hot here but i don't what version i installed.
You won't need the cold weather version in the Bahamas! :roundel:How do you know the diffrence? if it is cold or hot weather version. i did mine less than a year ago and it seen to be going bad again i live in the Bahamas and it is mostly hot here but i don't what version i installed.
I finished the installation tonight on the crankcase ventilation/oil separator and it wasn't too bad on my 2001 530i.12. Installing the connecting line is the most difficult. It requires you to rotate the line about 1/3 turn to lock the line onto the CCV (practice this connection process on the bench). The other hoses use the locking snap connectors that just insert and snap to lock. After trying for over 2 hours to assemble these parts in their location , I was unsuccessful and decided to modify the locking mechanism. Use a Dremel tool and a sanding cylinder to sand the two retaining ridges on the CCV nozzle smooth from about 1" long to about 1/3 inch long (see photo). This simply reduces the rotation required to lock the connecting line to about 1/8 turn (~45 degrees). Mark the spots with paint where the connecting line aligns with the CCV nozzle to aid in assembly (see photo). Insert the connecting line into the original position from above the intake manifold. Much wiggling and bending of the line is required to get it into place. Once the lower connection is in place, insert the CCV into place. Align the marks, insert the hose into the CCV and rotate the 1/8 turn. This whole process took 10 minutes (vs. over 2 hrs!) with a minimum of effort after modifying the parts! Insert the upper connection line to the engine nozzle until you hear a click. Insert the CCV screws and tighten.
There is a kit available that combines a few partsI'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:
- Pressure regulating valve (cold weather version, 11617533400 = $66)
- Vent pipe (cold weather version, 11617533398 = $28)
- Connecting line (cold weather version, 11617533399 = $34)
- Vent hose (cold weather version, 11157532629 = $15)
- Return pipe (stock version is already insulated, 11617504536 = $34)
- Dipstick guide tube (redesigned version sans concentric rings, 11437531258 = $41)
- Dipstick guide tube lower o-ring (19.5x3mm, 11431740045 = $2)
- Vacuum hose black (not on all E39s = $15, e.g., not on the M54)
