I have read all the above post and find myself in a bad spot. I to converted from R12 to R134 last year after my compressor went out and the new one I bought online was set up for R134. I replaced the reciever/dryer and the expansion valve along with the new compressor, tested it, and then recharged it with 134.
Now my compessor is going out again, I think. just this afternoon it started making noise when I would turn the A/C on. The clutch would engage and then just lock up after about a minute or less. After getting under the car and looking at the compressor, it looks like it might be leaking some mineral oil. But I can't tell from where. It's not like last time where it just blew the seal out of the front of the compressor. It apears to be leaking from somewhere else.
So I guess what I'm asking is, can my compressor be fixed or is it history again? And will this just happen again in a year or so because the system runs at to high of a preseure.
Please help
