Air leaking from exhaust port

Replaced ride height valve (rear). Set ride height to correct setting. After about one min. Air begins to leak from the exhaust port on the ride height valve. Any clues?

Is the ride height changing? Could be just bleeding off excess air.

Could be bad valve.

Different ones work differently but our old ones basically are a lever inside that acts on the tips of what looks like tire valves.

Each one can be adjusted through the hole that the air hose attaches to set depth.

This sets the sensitivity and dwell angle for lack of better term of the valve.

Ours had exhaust set in just a bit much so the valve would apply air to raise the unit then also let air out at same time when at position.

You can test by placing unit on jack stand then manually operating the valve by removing link to axle and see if lowering stops leak.
