An Air Leak Question

Is air a molecule or a composite of elements?

I'm going to use 134 once I create a tee in the steer compartment and put a 134 valve connection along with the schrader air fitting. That puts air to the entire aux system (or freon) and I will start searching again. I don't think that anyone that has not gone through the search process can ever appreciate all the potential sources for leaks and the various subtle ways a leak can be present and still undetectible.

One thing I know for certain. I would never turn my bus over to a mechanic and ask him to find a leak. I would end up sending his kids through college and him and his wife on a trip to Hawaii and my bus would still leak.

Having a air leak free bus is a journey not a destination. Enjoy the trip.

How well I know. I worked every night for over two weeks on the floor of a cold barn getting bus #1 leak free and that included the entire suspension system. For a long time it was, but as you might guess over time the compressor ran more and more and it leaned sooner and sooner.

If I was in the Prouds I would have my people take care of my bus. We must all be nuts.

"Is air a molecule or a composite of elements?"

Mixture, not a molecule. Air composition can vary with location. Composite? Doesn't meet the definition (of many) I'm aware of. Good question, though.

I am just sitting here contemplating my taxes.

Yeah, and I am sitting here writing out bills. Guess what is getting done more? Bills or horseplay on POG?

:cool:Just think, If you owe taxes and don't pay them- you will be qualified to hold a cabinet position in the new administration. All that is necessary to make things work is say "I'm sorry".

If you for sure owe taxes and pay them : You are a Great American.

Jon,

You could add some dye to the 134, pressurize the system then go on a sightseeing tour. The product is out there and available, believe, as I recall, the leak will turn red.

I had a similar issue, turned out to be a failed one way check valve leaving the compressor...junk, how I don't know, go into the check and it produced and agonizinly slow leak...really slow.

I'm sorry.

I agree with the dye, but part of the problem is that a relatively small percentage of the fittings or devices permit visibility all around the part.

At least with bubbles or a sniffer i get some visual clue, but with refrigerant as you are undoubtedly aware often times there are visual clues such as an oil stain, but like the one typically found behind the OTR compressor it is behind the clutch and not visible.

I need something that makes it really visible such as blowing bubbles or a freon sniffer to at least get me in the general area. Or I need someone to do this search mission for me. I'll supervise.

Jon,

A guy in Houston that I have been talking to about using R-22 says that there is a reason he uses 22 instead of 134. Something about one has a ? make up and the other has a ? makeup. I have not got into using refrigerant yet I have just been looking into it for a year or so. I just remember him saying that 134 doesn't work nearly as good or if at all.
