Re: AC Issues
No you did not put the right amount of oil in, if you added 9 oz., and that's probably why the system is making noise and varying the cooling......
When you get a new compressor, sometimes they come wet(meaning they have oil in them), or they come dry.....If wet, you are suppose to empty them completely.....
Now, you were suppose to take your old compressor, remove the the drain bolt from the side and drain it into a measuring cup.......If you drained LESS THAN 2 oz., you put 2 oz. into the new compressor....if you drained more than 2 oz from the old compressor, whatever you drained out, you add the same amount to the new compressor(if you drained 3 oz., you add 3 oz)....the whole system holds about 8 oz(this will be stored throughout the system in low points) like the accumulator, the condenser, the evaporator and compressor, etc......so if you added 9 oz of pag, you have overfilled the system with oil, which will inhibit cooling....you should have added the proper amount to the compressor as I outlined, and you should ave added 2-3 oz to the new accumulator......the excess oil can reduce heat exchange in the evap and condenser, and also cause a chugging sound in the compressor....
If you have a leak, and there was none before, then the leak has to be where you opened up the system....the compressor and the accumulator.....if the black light does not show the dye, then try a soap test at those joints.....
