Held vacuum all night, to the exact numeral! Tapped a can of Freeze12 to guages, and started to let it fill the system prior to turning on the wagon. Hmmm, what is that hissing sound under the car? Well, that would be a bad seal at the suction port of the manifold!
Walking away for now.........

That's got to be aggravating. Maybe it's the manifold. From the pictures, it looks like that could be an aftermarket version. Mine is original and it does not look quite like yours. Checking it for flatness might be worthwhile, if you have not already done that.

WoW, the perfect example of a vacuum not pointing out a pressure leak...

There are postings in the Dallas area saying that Freeze12 supply is getting low... are you the cause of this ?
LOL

Jimmy, don't worry , your system wouldn't last long with Freeze12 in it anyway... did you see those oil miscibility tests on that site the other day... ?

This should not be surprising. A perfect vacuum would be equivalent to 15 psi guage pressure. The first can will probably have the system above 15 psi.

Holding 250 psi is far more difficult than holding 15 psi.

I've been wanting a white TD.

Mostly it has to do with the moveable items like seals being pulled inward ( vacuum ) or pushed outwards ( pressure )...
LOL... I did not say perfect vacuum.. I said perfect example..
Others lately have seemed to be using the vacuum as a leak detector instead of for moisture evacuation.... followed by pressure testing for leaks...

The seal is designed for pressure. Therefore, it should be more durable under pressure than vacuum. So, if it holds 29" of vacuum, one could reasonably expect it to hold 14 psi.

But, holding 100 psi.......or significantly more........is a completely different game.

The pulling of the vac was to get rid of any moisture. I was not trying to pressure test using vacuum of course. But my original leak would leak down vacuum, so it becomes an observation, not a test.
I'm certainly not sold on these stepped port compressors. How many times can I go through this process before my rec/dryer is compromised?

If you did not expose the dryer to open air too long then it will be fine.

I would imagine that there was positive pressure in the system when you started, then you pull a vacuum to boil off any moisture that you introduced when you opened it up. So, don't worry about the dryer.

How many times before its comprimised??? Around four.

Man I feel for you. I hate those stupid simple little issues that hold a project back.

It's parked!

I talked to my Indy today by phone, and he told me the stepped port compressors need a green washer and a red washer. I told him my kit came with a green and red washer, so I pulled it all apart again and installed the green and red washers. I'm not sure I have the correct red washer as the suction port is larger than the discharge, but the washers are the same size. No lip on that side of manifold, so I just tried to center it the best I could while tightening. Upside down. Under the car. With the mosquitoes...
I've been pulling a vac on it for almost an hour and a half. Tomorrow I'll add the second half of the can I used for "pressure testing" the other day. Will report back prolly tomorrow, if I get home in time to work on it before the basketball game.
Poor Mavs.......

No lie. This evening I was in the garage filling SWMBO's car with WVO and daggone near got carried off by them!!!

Thing One heads back to Idaho tomorrow and the SDL comes back to me...still w/o airconditioning. I'll probably be fiddling with it again by tomorrow night. With the mosquitoes...

Are you having to rent a pump?

I have a two stage pump that sits 95% of the time. If you need to use it let me know.

Anyone else ready to pressure/system test their A/C with R-290? At 90 cents a pound? I know, but it worked for me. Most folks just don't take A/C very seriously on the NE shoreline.

listen, look, .........and duck.

For those that don't recognize the joke.. R290 is Propane... great for BarBQue grills...
If used for to pressure test ..... and then you use a propane bottle with the halide tips for looking for leaks (open flame)... lots of excitement potential if you have a leak...
