Start of this year I noticed the A/C wasn't cooling very well, so I charged it up and started leak checking, found that a service port was leaking so I replaced the lines and dryer/filter. When I did this I shot a can of oil charge in first, followed by 134 till correct pressures were reached. I noticed that it would not really cool well until the engine had gotten above 1500 rpm or so, and basically acted like it was a bit low on 134. It still worked fairly good, so I just ignored it and didn't think to much about it.
About a month ago I had the joy of hearing something let go in the system and the A/C quit cooling again, knowing I had a heater core leak I figured it to be the evaporator giving up under pressure. This past weekend I got the dash out and replaced everything, pulled a vacuum on the system and let it sit overnight. The next morning it was still holding good numbers so I shot just 134 into the system until pressures were correct, added no oil.
The system acts like it did before, cools really good so long as the engine RPM's are up a bit, just OK at idle. I kept track of how much 134 went in and it was 1 full 12oz can, about 3/4 of another one. According to the sticker on the radiator support, the system should take 2lbs of gas (32oz) and I figure I put in about 20oz, so obviously something else is taking up room in there and the only thing I can think of is added oil.
What can I remove and drain with the best chance of getting some out? From the sounds when it is shut down, there is a decent bit trapped in the condenser so that is my first thought to get into. My plan is to yank it off, drain it out into a container and see how much I get out, sound reasonable?
I'm new to doing A/C work, the buddy I had who handled it for me before is gone, so I'm learning as I go LOL
