Air leak

[Keith Moffett]

I am tryng to isolate an air leak.  I loose about 30 pounds over two hours and almost all the air over night.

I have covered most of the air lines around the two tanks using soap and water, no leaks at all.  

Are there areas more likely than others?  Any suggestions?  If I find a leaking fitting or God forbid a pin hole what then?

Keith,

Mine leaks from the cylinder on the close out for the steps.

Pain to get to and I have not tackled that job, yet.

Our 1997 Patariot had a push in type manifold in front of the front axle that had one air in and four air out hoses. It started leaking on a trip to NC and the front suspension would bottom out.

Does your supension air bags deflate when the air leaks out? If either the front or rear deflates I would check those and the ride height valves. If the air supension does not deflate some have mentioned a pressure relief valve on the  engine mounted air compressor.

If you are in a very quiet spot. Air up at night (when sound travels better) and walk arroud and under the coach and you may hear it.

You might also check your drain valve at the bottom of your air tank.  I hunted for several weeks and then some one told me to be sure that was tight and it moved less than an 1/8 of a turn and the leak stopped.

Gerald Burns brings to mind the idea that your quick connect port, if you have one, might have a particle interfering with its closure/seal, or as he suggests, a purge port might be slightly skewed.  Our coach has a "manifold" of 4 purge ports and a quick connect altogether in the battery bay, but many are located up front near the genset.

 What I found on mine was the valves that control the ride height were composite bodied valves which were cracked and leaking air. Might want to check around those.
Good luck

Under the hood just below the passanger side windshield are a couple of connections.  One is a manifold and goes partly to the floor slide panel.  The other is an electronicaly controled module with one air in and one out.  This unit is i/2 plastic electronic switch and 1/2 brass air fitting.
I have no idea what it does but the joint where plastic meets brass is leaking a fair amount.  Guess I get to call Larry in BCS parts.

Hope this helps someone else
