I had a leak in the evaporator.
I used the pressure guage they sell at walmart to add some sealer and about a can and a half of 134a.
It works fine now. It hasn't leaked since the beginning of the summer as far as I can tell.
It works ok anyway.
I noticed here some people talked about lubricating the compressor.
Do I have to lubricate it and if so how do I do it?
Too late, you already put sealer in it now you are the only person who should ever touch your system again. If you ever take it to a shop please be a man and tell them that you put sealer in it as not to damage their equipment in case they do not test for sealant. Either way, be prepared to pay more for service next time around. You have to find out what kind of oil your system requires and how much does the compressor hold based on the model of compressor and the type of freon. On your next repair you will remove the compressor and drain it and put in the correct type and quantity of oil, do not assume that the amount that poured out is the correct amount, big mistake.

Give all the dirty details
and dont forget the LO & HI pressures
Year, Make & Model would be nice too
Prepare to not only replace the leaking evaporator, but each and every component in the system - in other words, a total system replacement.
If you were losing refrigerant, there is also oil that goes with it that must be replenished. Probably a moot point now, given the likeliehood the sealer will finish the system off in relatively short order.
There is no sealer of any kind for any purpose that will do any good for anything.

Don't ever open the system, for then all the sealer will harden in all the parts and you'll have to replace everything to make it work again. This was apparently a former R12 system, do you know how it was converted, or if it was converted, or did you just put some R134a in on top of the remaining R12? In that last case you might add a can of ester oil (Don't use PAG, it reacts with R12) under pressure. But mostly all you can do is drive with your fingers crossed.
Legs.
If you can limit your A/C compressor duty cycle for driveway usage only and utilize a window mounted swamp cooler clamped to the drip rail for over the road cooling your present compressor could last for 2 1/2 more years without lubrication with a high degree of reliability.
If you can just wait until 2010, I've scheduled a Patent Pending lubrication free compressor out of R&D with following features:
1) R-IV - New Hi-Lubrisity Refrigerant
2) PTFE coated scrolls
3) 1200 degree grease for sealed bearings
4) Shaft seal solid lube with added feature of micro TXV for shaft seal cooling
5) Oil impregenated sintered metal thrust bearings
6) Graphite impregenated ceramic shaft bearings
Please be patient,
Old IV guy

Ice-n-tropics,
Yeah but how will it hold up to sealers?
Can you add a debris free failure mode?
-------------------------
HECAT,
Sealers are activated by exposure to moisture, so, we could bring back silica gel desiccant and pack it into the crankcase space that previously was the real estate occupied by oil. Moisture would get grabbed by the silica gel before the sealer could mix with the water which ingresses and the recovery machine would not get plugged. Ecologically correct crushed and recycled wine bottle natural corks will eventually replace artificial silicon based sealers anyway due to proposed EPA reg's.
As for debris free failure mode, my 010 MY compressor has a "White Anti-Death" failure mode which never requires flushing of any sort. White Anti-Death is a tasty type of grits breakfast cereal which not only lowers cholesterol but is also formulated as a R-IV refrigeration enhancer and will replace "ICE".
Cordially,
Old IV guy

I knew there had to be a better use for grits than eating them.

HEYYYYY...be careful talking about 'grits' like that......after all...remember where you are located.....in the 'deeeeep' south.

I am a Georgia boy and understand the many uses of corn such as on or off the cob, creamed, and the sooo important mountain squeezin's. Never obtained a taste for the item ground up and served for breakfast; although with enough cheese I can be persuaded to indulge at fish fry time. Mostly I grow corn to feed the hogs. Now I understand I may be able to help reduce our dependency on foreign oil and provide material for the "White anti death mode" in future compressors. who new?
-------------------------
I am guessing that is the opposite of the AC Anti Christ or Black Death, or something like that, so it must be a good thing.

HECAT and other Grits Lovers Everywhere,
Down in Bossier City, LA, Grits Capitol of the World, on Oct. 6 they had a grits eating championship. Pat Bertoletti was the winner after gulping down 21 pounds of corn grits in 10 minutes. Now there is a real hardy breakfast that will provide a new technology for pulsating flushing.

So we can look foreward to Hecat's new "Spastic Colon" model of flushing machine to remove the excess grits when the "white anti-death" mode goes astray and the evaporator begins condensing Co2 from the atmosphere?

21 lbs of grits! That is a colon cleaner!
Shhhh.... can't talk about medical applications until the trials are completed.
-------------------------
Now if the correct ratio of butter...mmmmm creamy...sweet....to a portion of grits is maintained.....it seems this would be sufficient to result in a possible rapid expulsion of this material thru the rearward mounted ejection port...and may result is a vacuum being applied to the brain as this occurs.
Grits...no cheese please....fried fish....filets or the entire fish.....baked beans.....fried corn bread or hush puppies...with either corn niblets or jalapeno mixed in.....cold sweet ice tea....you know the tea that one can see the sugar swirls...yep.....almost glucose......damn...thing of heading back to 'Jawja'
