I bought one of these used from here, and I will be installing it soon. It came with 2 O-rings: a big one to seal the adapter to the car (the same one for the original style canister) and a smaller one. I do not know where the smaller one is supposed to go, or where to get a new one from (since the one that came with it is presumably used although it seems new)
I found these instructions here:
Spin On Oil Filter Adapter for Porsche 911, Boxster, Cayenne S/Turbo, and Cayman models
That say:
"Lubricate both o-rings prior to installation with appropriate o-ring lubricant."
Has anyone that has got one of these new let me know if it came with 2 O-rings and if so where the smaller one goes?
I have got the previous version that includes a tool for mounting it on the car, instead of the built-in nut like the newer ones (shown on the linked page above)
Thanks
Steve
