I performed a rudimentary leak down test (straight from the air compressor, about 20 psi).

No sound or wind coming from oil filler cap, or radiator reservoir. Didn't check the intake valve yet, but I did hear it at the exhaust (and I felt it).

I watched Eric the Car Guy's video on leak down tests, and he said that air heard/felt at the exhaust pipe would be an exhaust valve leak (? I think thats what it was..I'm not at the video right now).

I will re-test it later today (I have errands) and hand cycle the engine to DTC in cylinder #1 again, and post results.
