Before I had any experience with what "usually" fails, I had this very same exact problem. Given that it is hard to hear leaks with the engine running, I decided I needed some other way to pressurize the system and find where the leak was. I did this by obtaining a regulator and an air source where I could attach 700 PSI of air into any point in the system I wanted. Since I made this rig, it has been invaluable numerous times. Emphasis on having a good regulator! After the snot valve, the air line goes up to a central fitting where there are check valves and also the over pressure relief valve, or "pressure regulator" if you will. The brass fitting with rubber end and spring deal, that if you don't know intimately now, you soon will. Detaching that and pressurizing the line BACKWARDS, forcing air back towards the compressor quickly found the problem. The "output check valve" on the compressor, I.E. Exactly the one Walter was talking about. The next time it was the Banjo Fitting that is also part of that whole "output check valve" mess. Why? Because I did not replace the aluminum crush washers the FIRST time I repaired it. Lesson learned. Yes, I have had the snot valve leak as well, but always to where I could hear it as soon as I shut the engine down. Never-the-less, reverse pressurizing the line proved that one too. I despise being reduced to 'dive bombing" or "shot-gunning" a problem. When I have an electrical problem, I go grab a meter, a scope, a watt-meter, whatever. Just like not running for a crescent wrench and instead having a good set of wrenches in EVERY size! :-) My point is that when you have an airplane that incorporates compressed air for a number of different functions (flaps, gear, brakes, etc.) it is incombent on even a backyard mechanic to have some tools to deal with it. Making something like this is not exactly "trivial", but it is a necessary addition to Yak and CJ aircraft owners who desire to do their own troubleshooting. Otherwise, get used to "changing shit" and then wondering whether you just fixed it, or made it even worse.
