I am by no means an A/C expert, so this may be the wrong answer......but when my little truck with a R134 system stopped cooling well, I figured to go to auto supply store to get leak detector and figure out where it was leaking. Well, when I got there, I found that they have a self contained unit that does it all in one shot. It is a large can of refridgerant, with hose and gauge attached. The refridgerant includes oil/seal conditioner and leak sealer.
It was $20 or so. All you do is fire up the vehicle with the AC on, take off the low pressure cap, and hook up the bottle. Take a baseline reading, and then pump the needed amount of refridgerant into the system and ....wala! It's cool again! I did that about 2 months ago, and have been checking the pressure every week or so...and haven't lost any more coolant. Looks like the leak sealer worked. How can you beat that for $20?
