AC Help: Did I blow something from high pressure?

[10aCMike]

After replacing all of the components in my ac system except for the lines, I finally got the system to pull and hold a proper vacuum for over 12 hours. I needed to add more PAG oil, but didn't desire to open a line so I bought the PAG oil charges in the can (2 fl oz of oil, 1 oz of R134a). With the system holding a -29 vacuum I attempted to add the oil to the system through the manifold gauges. When I opened the low side valve the pressure shot up over a few minutes from vacuum to 120-130PSI, but the can of PAG and refrigerant never went into the system. The compressor never engaged. After working with it for an hour I closed the low side gauge and let it sit until the next morning. I checked the pressure and it held at the 120-130PSI over night. The city temperature went up to 86 degrees that day. When I went to work on it that afternoon the system was flat and now there is a leak. I assume the pressure caused something to rupture, and if so, what would be the likely part? A line or worse? Thanks.

Well, I don't know myself. I do know that 86 is freaking hot with no AC! Maybe someone else knows the weak points and they'll see this thread. Until then, you can flip your way through all the troubleshooting in the FSM for your AC system. Here's a link to that chapter:

PS I like the username! Except now that Arrested Development song is kind of trying to take over my thoughts.

sounds like the manifold is holding the pressure. one can of oil will not be enough to get an ac system to 130 psi. 130 psi should not blow any lines or safety valves aside from damaged ones. and if it did it would show 0 psi as it would have vented to atmosphere.
