I asked Gena Elfimov about it and his response was that it is not unusual. I don't know what causes it and it doesn't seem to be much of an issue with the Russian instructors I've flown with.

    Subject: Air leak - Don't have much more hair to pull out.
    --> Yak-List message posted by: Aubrey Price <aprice@vartec.net> Last week my YAK52 started leaking down at night ( main system only ). I have checked the pop off and put soap on every connection I can find. I have disconnected the down stream side of the main air valve and checked to see if it was leaking. I have checked at the fill port and it isn't leaking. I have removed the airtank, inspected and soap tested it and the fittings.I have had several people that have great hearing check and have found nothing. The leak is getting worse every day. It will leak from 50ATM to 0 in less than 24 hours. I think there is a check valve somewhere that I am missing.I tested the check valve near the filler and it's not leaking. This almost has to be a leak inside the system or I could hear the leak. The drawings I have of the system are bad quality and hard to read.Yesterday I pressurized the system with dry Freon and used an electronic devise to sniff for leaks. I found one small leak that wouldn't change the system pressure 1ATM in a week. Since the Freon detector never found anything inside the aircraft, I have to assume the leak is between systems. I cycled the flaps and the detector went wild, so I know it was working.I am open for all suggustions. Aubrey Price N288Y

The leak was staining the tank but I guess it was leaking when the fuel level reached the top of the vent system. This fitting would leak if you went inverted.

It turned out that the valve seat is aluminum while the valve itself is common steel. What I found was a nice ball of rust (valve) and a very very thin grove on the valve seat. It continued to leak even after replacing the valve with a stainless steel valve from Bill Blackwell.

    Subject: Re: Air leak - Don't have much more hair to pull out.
    --> Yak-List message posted by: "A. Dennis Savarese" <adsavar@gte.net> The check valve near the air fill port on the 52 is for the emergency system. The two check valve on the firewall at the right and left side of the pop off valve are for the main air system. The one on the left is from the air fill port. The one on the right is from the "snot" bottle. There are also two check valves under the rear cockpit floor on the right side that go to the brake reducing valve. One from the main system and the other from the emergency system. Did you check the connections at the gauges in each cockpit? I have seen a connection on a gauge leaking. There are two separate connections on each gauge; one to the main system and one to the emergency system.
