thanks for the tips. I plan on using R12 freon. the system held pressure fine the last time around, even w/ a mickeymouse repair on one rubber line. the failure was the compressor- it started rattling and I removed it from service before black death could result(i think)

would it be bad to flush now,(exp valve forward- unhook lowside @ compressor , and highside at comp, too??????) and do the compressor, valve and (lastly)drier next week- or do it all at once- I plan on charging away from home, so I want to do as much work here as possible.
