I would try connecting a piece of rubber hose to the vacuum gage and stick the other end into the dipstick tube. Choose a rubber hose that has an outer diameter that fits the dipstick tube and seals.

The I.D of the dipstick tube is like 1/2"

Maybe a rubber vacuum port cap with the end cut off?

After all of that on my car it's not enough to even measure. The needle moves a tiny amount but it's less than 1 in. and the gauge I have isn't designed for that kind of accuracy. We can try Rando's car next time I see him.

Sounds good. Thanks for the update. Hopefully John's car shows what a properly working system should have. When I tested my car it had no vacuum at all. At least yours has a small amount. It probably will turn out that even with a new CCV there is only a very small amount of vacuum.

Anytime in the afternoons this week is fine for a quick test.

Did you happen to look at the tubes under the plenum? Were they clogged, cracked or in bad shape? Now I'm considering going back and doing this. I did all but that and a bunch of other stuff at about 102k, I'm at 126 now.

They were not (if we are talking about the same thing)

Awesome, this makes my OCD twitch less noticeable.

Passenger air bag recall done. Next up is OFHG and Oil Pan Gasket.
