Aren’t air leaks fun…. I’ll be chasing aux leaks for some time, but at least my suspension is tight..

There is no more active topic that frustrates owners than leaks in the air systems, and there is no issue that can drain a wallet faster. So as a result we either accept the fact we will go broke having mechanics repair air leaks, or we drive ourselves crazy chasing them ourselves.

Having said that it is possible to create a “leak free” coach. The term leak free is not quite correct because there will always be some loss of air pressure over time, but in the context of going days before the gauges move or the coach leans we can call a coach leak free. The effort to get to that point is exhausting because the big leaks are the easiest to isolate. Where it gets very time consuming is chasing the small ones that by themselves aren’t significant, but collectively will result in unacceptable pressure loss.

And there is no silver bullet. It would be great if we could add a magic leak repair gas or liquid to the pneumatic systems but there is no such stop-leak product.

So the solution is simple. Take your leaky coach to your favorite converter, and trade it in on a new coach with a warranty. Or you can turn it over to a repair station for leak repairs. The cost will be the same.

Yea that “trading in thing” is not one of my options right now plus that warranty means I got to get it to them every time i got a problem ! I figure investing @$35K in interior/exterior upgrades is cheaper than trading for a new set of problems! If one can get to the point of knowing your Bus and able to work on certain aspects of it (and enjoy it to a point) then you know what you got. Talked to a new 2013 Bus owner last year who had a list of 28 items to fix after 2 months ownership and had to drive back to florida for repairs.He wasn`t happy since he could`nt get it done local or them send someone to him.Price of ownership!

That`s great Tom. Tks to this site and knowledgeable people it`s very mangeable for me. WX seems to have the biggest effect.

Usually the cold shows the leaks and warm weather corrects them.

Typically as something is beginning to leak it never shows up until a cold spell. Then when it warms up we start to think the leak repaired itself because it seems to stop leaking. After a while we learn that is not true.

I think when push in fittings were used the advantage was in the assembly process. The disadvantage is as our coaches age the vast majority of our leaks will show up in those fittings. If they can remain undisturbed they seem to show less leaks, but if they have to be touched for service or any reason the plan should be to replace them.

If the suspension is worked on such as air bag replacement a significant number of the push in fittings can be expected to leak and at that point you have to decide if you wish to replace them with the same type or go with compression fittings.

I had a 1997 royale last year I did replaced all air fittings with comp fittings and replaced air dryer and R14 valve and other things , norgerns etc , mine would not lean forever and all three gauges would hold air for months it’s not one thing that fixes air leaks but a lot of small ones but every one is a leaker and you will get it done if you go slow and don’t give up , I put a lot of ball valves in and it helped , I will do my liberty this winter and change most of all the push in fittings to comp fittings
