No, the oil continually circulates. and, when they say that the oils are
incompatible, what they are saying is, if they are mixed, the result is a
gooey mess.
In talking to A/C guys I have been told that if you are going to replace the
compressor anyway, it is just best to bite the bullet and convert it over to
R-134A. The compressor is the weakest link in an old A/C systems and R-134A
runs at higher pressures than R-12. You have to replace the
accumulator/dryer and then do a fluid flush on the remainder of the system.
Commercial refrigeration suppliers can supply the flushing agent.
As far as the high side hose (with the orifice in it) goes, I have not
seen a different listing for R-134A and R-12 hoses.

Yeah, but then every time a little leaks out and I take it to the shop to
get it topped off, it's $50.
The R134a is so cheap, I figured it might be worth a shot. For $40 I can
get enough R134a, the green neoprene rings, the proper fittings, and be
done.
Here's the real question. I understand that the R12 oil isn't compatible
with the R134a. The best way to get the old oil out is to let the a/c run
for awhile and then vacuum everything, right? I can't run the a/c for any
amount of time, so I'm not sure how to get the old oil out. If I were to
replace the compressor, fill the system with the R134a, run the system for
awhile, and immediately evacuate everything (hopefully including the oil),
couldn't I then put in brand new R134a and oil?
So many questions. So little time ;^)
Thanks again everybody for the help. Keep it coming!

Just get the R12, it isn't THAT bad.....maybe $100 max for a total fill.

You think the cost of the R-12 is worth it? It will cost a bundle, no?
I figured I could get a conversion kit with new rings, the R134a, and the
fittings and be somewhat happy.
Thanks,

You already mentioned less efficient. It is WAY less efficient. Also, there
are
official Ford kits out there to convert to R134a. Don't just go to Autozone
and
get their $19.95 kit.
If it is just your compressor that is toast, redo it with R12.
