ACIS vacuum leak
Found a bad vacuum leak sucking air around the output shaft of the ACIS on the side of the intake plenum. I've been searching for some kind of replacement seal for this shaft with no luck. Anyone have insight on this mysterious part? Is there even a seal? Do I just have a worn out part?

There are two seals:
17300-20020
17127-62030
The 2nd one is for the plate to plenum, 1st one is part of the ACIS assembly. If you have a leak where the shaft goes into the plate you'll have to replace the ACIS valve.

Closer inspection, if wound up being the plate to plenum seal. I guess the leak was strong enough to suck the starting fluid spray around from the side. All is good, with that for now.
