The pressure side line to my AC Compressor loosened up about 1 year after
replacing.  It was cooling fine, then as the connection vibrated loose, it
discharged oil and R134a, I shut it off as soon as it stopped cooling.

I was surprised it came loose, as it was tightened up pretty snug when I
installed it last summer.  I guess this may be something to check on a
regular basis.

My question is, since I observed AC oil under the van, do I need to replace
or add additional oil before recharging it?

If so, what is the best procedure to do that, and do I just add the proper
level to the compressor?
