A/C PROBLEM

Got in one day fired it up and no air. Thought the freon was low (uses a can a year) come home put part of a can in compressor kick on and off like they do. Except this time it is blowing freon out somewhere under the intake like a poppet valve or something. Can't see where it is coming from it only does it for a split second and when the rpm's are up around 2500 or so. First thought was I have to much freon it. Vacuumed it out started all over and the same thing. any ideas what it could be is there a pressure relief valve under the intake some where?

what pressure do you have on the high end ? If it only does it for a second and hi RPM, it does sould like pressure pop off. Didnot know it had one.

TUbe is inside the hose/ line at the radiator/ coil area. You need to put the gauges on to get the HIGH side pressure to see if that is really the problem. If you have very low on the LOW side and very high on the HIGH side - it can be the orifice, but you need to confirm.

I did use a can of super stop leak. I wonder if that could have clogged it.

Not a betting man, but that sounds like a sure one... Philip
