General question : pulling my '64 O/T car's motor for rebuilding. Has factory A/C. Low pressure port hisses softly, so maybe there's vestigial freon left - years ago when it last ran the A/C didn't cool. Thinking before I throw too much money out the window on my (unplanned) rebuild, I would just not re-hook up the A/C. Also, want to freshen up the engine bay while the motor is out, and the hoses/compressor sure would be better on a shelf for that. Is it advisable to disconnect & remove the compressor & the hose to the condenser and to the blower? Would I then get a suitable tight cap for each to keep the system relatively clean? I assume because of the age of the system and the last time it ran, I'd be looking at a full bore test/service anyway if I wanted to run the A/C. Or should I just put everything back in its place?
