Instead of using my left arm to reach around the motor, I used my right arm.

It's not unusual for Porsche to make running changes/revisions to parts and the earlier version can be used untill the supply is depleted, then only the latest revision will be available.

Just double checking.....were you able to install the "newer version" of the hose in an earlier 996 (1999-2001)?....

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Looking to replace the corrugated AOS (996.2) line and I noticed (on my other failed motor) that there are two different types of AOS breather tubes. One is all corrugated and the other is a hard line with a 8" corrugated section attaching to the AOS, the attachment point on the right side (head) has a breather.
Which one is better?
On the right you can see the breather that the hard AOS line connects to. Are the connection points the same for either line?
Here's the hard line...
Ignore the red arrows.
I just did mine last month (2004 C4S 996.2). It was the fully corrugated one. I can't say if it's better or worse than the other type, but the one I got from pelican parts was an identical replacement to the one I replaced. Part number was 996 107 147 59

The porsche parts catalog (below image) shows a different part number up through 2001: 996 107 147 55

The 55 part looks like the one that is mostly solid and corrugated only at one end. So if you have a 996.2, I'm guessing you need the 59 part.
Yes, the job wasn't as difficult as I expected.
Getting the old line off the AOS and the new one re-installed was a lot easier when I figured out how to twist my body. Instead of using my left arm to reach around the motor, I used my right arm. This means basically rotating your body 90deg, looking toward the left of the car. Then you twist your wrist so your palm is facing backwards and Voila! it was easy to squeeze the end of the AOS line to unlatch or latch it.
I would go with the most recent/highest revision number for your year model as dc states 996 107 147 59. It's not unusual for Porsche to make running changes/revisions to parts and the earlier version can be used untill the supply is depleted, then only the latest revision will be available. Sometimes there are significant changes in appearance or material, sometimes the revised parts look identical. Even a vendor change will get a revision number. I find it best to use the highest revision number when possible.
Bumping an old thread. I am working on the UAOS and i order a replacement for the lower AOS crankcase vent hose. Well long story short, my car is a 996.2 C4S 2003 and it has the 55 part number with the check valve. The new kit i ordered has the 59 part. My engine only has one bolt hole. How do i get to use the 59 part or a 55 part is the only one that will work? I prefer the 59 part because it is way more flexible!
Thanks again guys!
I'm afraid I'm no help. It's strange that you only have one bolt hole. My 2004 C4S originally had the fully corrugated two bolt version, and a new fully corrugated 996-107-147-59 worked fine.
AutoAtlanta lists the 59 part number as working for any 3.6L '02 and up, and they only list the 55 number for 3.4L up to '01.

Someone more knowledgeable than I will have to weigh in on how you could manage to have a 2003 3.6L with the older 3.4L part.
EDIT: And I see that you got a better answer to the same question from Porschetech3 over in the UOAS thread. So... ignore me.
