Those are two different things.

Both but what I didnt check was to run the car without my brake booster line connected. I remember checking the check valve and replacing the line but I didnt check to see if my booster is leaking when I doing my engine bay up before dropping the motor in.
That would actually explain why im getting a leak even if I boost/smoke test it. All the postive pressure will push the ball in the valve closed not letting any of it reach the booster. Only when the car is on vac negative pressure running will the valve open up and suck on the booster which can be letting all the air in.
Going to just flip the check valve around, load the mail tune and run it. Thinking about it now it makes perfect sense.
