Glad you were able to locate the leak.  Was is a hose or metal line?  If a hose check for a metal ID tag with the manufacture date on it.  If a metal tube check it for abrasion and corrosion from contact with Scat air and defrost ducts.

It was right at the connector. The nut was loose. Braided Hose was fine. Didn’t fire up to check, but mechanic was certain it was the culprit.

I agree with the others here, wash the engine off very good with mineral spirits and a parts washer then add some UV dye to the engine. Run it a few minutes and then go over it with a black light that stuff is great

Byron, what fluorescent dye + UV illumination system do you use?

I bought a 395nm UV flashlight from amazon.  UV dye from the auto parts store. But evidently the oil glows under the UV light.

I use to work in an O2 clean room and all we used was blacklights, Oils will glow differently depending on what it is, the dye makes all glow the same color
