Well what a day we had! :confused:
It all started at the post office. After being in Canada for about a week or more, we had our mail held and delivered... well we thought it was all delivered. I had to go to the post office and pick up three packages. One was a father's day present for my dad, the other was a new key/cylinder set for the 55 trunk and doors, and the other was a box of 6 cans of R134a (yep - I returned the Home Depot special - these 6 cans were much cheaper and the same brand

After my request to receive the mail he slapped down a few pieces of junk mail (which we had already received paper mail so I have no idea what this was about) and the package with the key/cylinders set. He finally decides it best to go get his supervisor. 15 minutes later my other two boxes miraculously show up. Fun times.
So... we get home and it's time to fill this AC system with oil and refrigerant and... "Oil? did we get oil?" I muse to myself. Uh... and out to the parts store. So... we got the oil, we got the refrigerant, we got the can tap and we are READY.
First up was to hook up the vacuum and let that run for at least 45 minutes (I actually ran it for almost an hour while getting some other things done today like some body work on the hood.) I was surprised how quiet the pump is - it never got that loud. The gauges looked good again and we were holding a good vacuum on the line without the pump (like before when we did a test run). Here is a brief video as well:

Close the valve quick and find that leak! When I found the leak I had to remove that section of line from the car and take it to the bench to re-crimp. When I got that done I reinstalled the line and fired it back up to load the refrigerant through the manifold. Hey! We got it going now - the clutch is engaging, the air is cooling, and we are on our way to...
What's that hissing sound? Yep - another leak. On the high side of course. By this time I am on my second can of R134a and I don't want to remove a section of line because of what I will lose. What can we do?
Take the crimper to the line and finagle a way to get it recrimped while still installed. Don't ask me how, but it worked and we were on our way!
I loaded up that can and started watching my gauges as we were starting to get close. We were not quite there after can number 2 and so we tapped in to can number three. Good deal - the AC is humming along, we aren't leaking anything, no squeals or what have you and the gauges are good. Successful job I'd say, let's shut this thing down.
Now to get a drink! (come back a few minutes later....)
Are you kidding me?

Obviously the high pressure (about 200 psi on the Hi side) overcame the crimp job I did on that particular fitting. So... off she came and we did a recrimp on another section of line. I cannot understand why if a vacuum held like it was supposed to why there was all this issue with leaks. Of course the vacuum goes one way and the hi pressure goes the other but this was getting ridiculous!
All is well that ends well. I feel like I wasted a lot of time correcting my own errors but there you go - Ford Follies in action. I did get the heater core lines run and another coat of primer on the hood so all was not in vain I guess. And, we do have cold air in the car!
