If it is a modern three-way ( the last decade or so) replace the 2-003 o-rings on the shaft. If it is older then there are a couple of o-ring inside that should be replaced. this retains to the standard acm/wgp threeway. other brands may have different o-rings. the other thing to check in an older ac is to pinch off the rear ram hose as in the stationary position air can bypass a bad ram piston o-ring and bleed through the exhaust of the threeway. usually ram pistons are -010 o-rings. both three way and ram o-rings are 70 durameter urethane is best but a quality buna o-ring is a common replacement

If the leak switches from one end to the other when you cycle the three way, check the piston seal on the ram.
