I changed to 134, because the thing did not work and 134 is cheap! The compressor did not engage, so my guess is that it had a slow leak (didn't work too well last summer), and I should add that I have put a sealer in it. I tried that Freeze 12 stuff, but it did not work, which seemed kind of odd. A bigger problem maybe???

I did get some oil out of the system here and there, but probably not too much. I tried to remove the compressor to drain it, but after breaking a few wrenches and gettting angry, I decided that thing aint coming off unless it needs to! Is there any good way to get oil out of the system without draining the compressor? I added, well, too much of the ester oil.

One question: If I do not replace the dryer right away, will the system still work so I can do some troubleshooting for other problems? For the time being, I am not looking for a clean, prefect system recharge.
