Hey Syd, Great write up! Your catch can looks like the one Jegs sells? The photo is deceiving, the unit isn't much bigger than a med pill bottle! I know, i bought 2 of them, installed one on my 13 Terrain, I wasn't happy, took it off, installed a much larger one from Home Depot (a Husky $24.), half the cost of the Jegs unit, they both are designed for compressors? Those white filters freeze up, I took mine out, & put in a stainless steel kitchen scourer, does the job & flows more air? Keep up the Good Work!
later, Boston Jim
PS, Just put on a FC219 vented oil fill cap, $14.-, from Napa
