I recently replaced my A/C compressor, expansion valve, drier,and the high low pressure switch, and aux fan temp switch. I removed the condensor and flushed it repeatedly with A/C flush, then blew it out with compressed air, then flushed and blew out the evaporator and the line from the evap to the compressor,.....blew those lines out from inside the car while the expansion valve was removed. And flushed and blew out the line up front with the muffler cannister on it. I didnt have time to complete the installation, so the system ended up being open for a few days to a week. I installed the new compressor, then the expansion valve using new green O-rings, (previously added the recommended 5.5 oz of compressor oil, then an additional 5 oz of oil divided between the not yet installed drier and the condensor (actually did this before re-installing it). I couldnt find any information on how much oil to ad to the system, I was directed to a web page somehwere that stated the A6 rotary compressor should have 5.5 oz, and then from there I just got drips and drabs of suggestions on total system capacity of 9-11 oz of oil. I never new for sure if any of it was correct. The freon requirement is 2.9 lbs of R12 or 46 OZ. I installed either 2 cans or 2.5, cant recall, they were 12 oz cans and I was just guesstimating as I was not using a scale (can a scale be used with the small cans?)

With the new drier in place, I vacuumed to -30 and let it run for an hour and a half or so. Charged with R134a and found on a 100 degree day I had 45 psi on the low side, 320 on the high side, and about 70 degrees at the center vent when driving.

The clutch on the (reman) compressor gave up after a few hundred miles last week,...............so, I have the system apart again, drained the oil from the compressor to measure it.

HERE ARE MY QUESTIONS:

1-When I drained the compressor oil it came out like bubbly champagne,....it took about 10-20 minutes for all the bubbling to subside--IS THIS NORMAL?

2- The PAG150 is fairly dark now, it was clear when I installed it, IS THIS NORMAL?

3-Im seeing something that I am pretty sure is a small quantity of water in the drain pan,...under the oil,...........I'm thinking this is NOT good......AND IT OCCURS TO ME THAT I USED COMPRESSED AIR WITHOUT A DRIER IN THE LINE TO BLOW THE SYSTEM FLUSH OUT,...IT WAS ALSO RAINING ON THE DAY THAT I INSTALLED THE DRIER, AND I REMEMBER SEEING SOME WATER DROPLETS SPATTERING IN THE AREA OF THE NEW DRIER AND THE OPEN A/C LINES,....THINKING THAT SOME MAY HAVE SPATTERED INTO THE OPEN LINES, OR THAT 100% HUMIDITY MAY HAVE COMPROMISED THE INSTALLATION.

I pick up my replacement compressor this morning, but will wait for thoughts on this before proceeding.

4-A fried has said that he has often poured out whatever is in the drier and added fresh oil of a like amount and never failed to have a system work after a vacuum and re-fill.....thoughts on this?
