Color me green with envy. I recently had my SC and IC off and apart for cleaning, inspection, and to add the tweaked and coated SC snout and valve covers that I've been sitting on for awhile. Anyway, when It was off, I pressure tested to 25psi for several hours, and it passed. I was almost hoping that it would fail so that I could get the upgraded IC. If price wasn't an object, I would have swapped it right then,even though it passed the test.
