One problem.. I found a mystery o-ring under my car while everything was apart.

Its dimensions are 12mm outer diameter, 8mm inner diameter, 2mm thick. It's not the dipstick o-ring because that is about the same diameter as the nickel. I looked through some realoem diagrams which didn't help. It was clean and dry when I found it, so it was either in a non-dirty location or it fell off the new CCV.
+1 Just replaced my CCV and also found one as well. I've got the old parts so I will look for a similar o-ring.
