Engine is out of the car for other reasons, and just planned to replace these as preventive maintenance.

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.

Bought two sets of the OE Porsche guides from Pelican, and they did not come with the green o-rings. Anybody have the o-ring p/n or know where to order them from separately?
Weird they did not come with O-rings. My pads I installed in November had them, pretty sure they were from Pelican. It�s a trivial cost, but I would still call Pelican and inquire.
In correspondence with Pelican and with the local Porsche dealer, the Porsche OE guide kit does not come with the o-rings and they need to be bought separately. The aftermarket kits that Pelican and other suppliers sell, do come with the o-rings.
My old version of PET does not show the o-ring p/n separate from the guide kit, so both the Dealer and Pelican were able to look up the p/n for me.
Pelican has the o-rings available separately, but I wasn't able to find them on their website w/o their help with the part number. They are around $14 ea. from Porsche or Pelican.
Interesting. I did some digging on this on the Sunset and Pelican websites, here's what I found:
996-105-253-00
Engine Timing Chain Guide- Porsche
$47.38
Comes with O-ring (can confirm, this is the kit I used)
Listed as NLA at Pelican but still available at Sunset
996-105-253-01
Installation Kit - Porsche
$39.28
Appears to be the part you ordered/received - no O-ring
Listed as superceding 996-105-253-00 by Pelican
Thanks for looking into it.
I ordered -00 from Pelican a couple months ago, and it shows -00 on my invoice, but the boxes received are -01. So that explains the omitted o-rings...
Also, when I discussed with the dealer parts guy yesterday, and gave him the -00 part number, he said the o-rings are separate and not included. So it may now be superseding in their system. For example Gaudin Porsche shows -00 as discontinued even though Sunset still shows it's available (?).
Either way, I've ordered the o-rings and hopefully they show up by tomorrow so I can continue putting everything back together this wknd.
Another follow up:
Here's the old guides removed. Somewhat uneven wear, the bottom pad for bank 1-3 is the worst. Seems concerning for approx 25k mileage (??).
What's typical age/mileage for recommended replacement?
are those the original guides?
some say softer material in the original vs new/replacement - but maybe age/heat/etc take a toll regardless of miles
what were your deviation #s before replacement?
would be curious to know if they changed much after replacement.
This is a source reference. Confirm exact model applicability in the original material.
