AC Compressor Rebuild Kits
Are there any available for the compressors on the V8? I cant find anything doing a search. Also would need a new clutch. I have some AC tools for pulling the clutches etc. I did rebuilds on the older A6 compressors before which was essentially an O ring kit... But I think if there was a kit I could buy, Id be able to tackle it.

When I disassembled it, there was no hiss sound from the lines when I took them loose from the back of the compressor and no oil leaking from it, no smell, nothing, just dry. So, I figure with a new compressor, dryer and expansion valve to start with, Ill have the system vacumed down, then refilled. Pretty much the only thing left to fail would be the condenser...which is likely ok.
The kit I mention is by Four seasons... any good?

Just a FYI the most common cause of AC leaks is 1: The front seal in the compressor 2: a crack in the main line off the back of the compressor 3: Stone damage to the condenser.
To do the job right you vacuum down the system and charge it up track down the leak. It would also be helpful to hear the current compressor run. When you said you wanted to rebuild it I assumed you had metal in the system. If you can hear it run and it does not sound bad al least you do not have to flush the system to get metal out.
Oil not coming out of the back of the compressor in a system that was not charged is normal. Without refrigerant there is nothing to carry the oil and it just drains back to the condenser/evaporator/drier.
I listed the most common issues but it could be a bad pressure switch or just a split o-ring anywhere in the system. Of course a new dryer is needed any time a system has been down for awhile.

Upon my examination, I did find the dirtiest part of the compressor was around the front and underside of it. The lines from the back were clean and dry, no oily residue... Dont know how indicitave of a clue those are, b ut thats just what I saw.
Im hoping that the compressor,dryer and expansion valve all being new will be a good start to fixing whatever was wrong.... My thought was to replace any moving part in the system as it would probably have the best chance of being worn out. For $226.54 for all 3, its not too bad of a gamble.
