I definately over charged it with oil...I know that for sure...the problem is how do I get it all the oil out? I've pulled the core out and emptied the whole sysem from the low side, and I pulled the lines off the compressor just to make sure,any suggestions?

 

How much oil did you put in? Oil by itself will not change your pressure reading that much, unless you put it in by the quart.

 

I put in the 3 cans of oil charge, 15oz each. The guage reads 100 lbs/in.

 

The 15oz cans contained 134a and oil

 

100 psi is way too high. The system won't cool at all at that temp. The low side should be between 20 and 50 psi, depending on too many variables to list here. Lower is generally better.

Do you still have the cans? They should say how much of the 15 oz was refrigerant, and how much was oil. If they contained oil, they should also say what type of oil it was. It will either be PAG or POE. It would be good to find out, as the two oils don't really like to mix. It sounds like you used 3 cans from a retrofit kit. If that is the case, they probably had 3 oz oil and 12 oz refrigerant in each can. That would make for 9 ounces of oil (about twice what it needs). While that may be reducing the performance of your ac system, it should not be preventing it from cooling entirely.

The only way to remove oil from the system is to evacuate the system, disassemble the components, and flush.

When you charged it with those cans, did you hold the cans upside down, or right side up?

Have you visually checked to be sure the compressor is engaging? Do you have a way of measuring the hi and low side pressures with the system running?

 

The cans were from a retrofit kit. I held them upside down as per the instructions. I currently dont have a way of checking the high side pressure, but I saw a set of high and low guages that I could afford. I'll buy em tommorow, then we can take it from there. Thanks again.

 

Hi from UK Scotty562.
Here we have a drop in gas - RS24. It directly replaces the R12 with no need for a conversion. It is used in the UK for agricultural vehicles and ice-cream vans etc. Is it available in the states?

 

Well Ive decided to go ahead and replace the accumulator, and try to purge the condensor with a very soft air gun. Hopefully this will solve this dilema of mine....I'll be back to report in an hour. Also I've never heard of RS24, anyone else?

 

I have posted some information found on RS24 which can be found on the website: http://www.bee-cool-aircon.co.uk/questions.html

Q. My car is an import, or was made before 1994, and has R12 refrigerant. Can this be re-gassed, or ‘retrofitted’?

A. We are also able to ‘Retro-fit’ older vehicles carrying the now banned R12 refrigerant. This was fitted to vehicles prior to 1994. We can use an industry accepted replacement gas called RS24. This gas, although expensive, will avoid the need to replace all the major mechanical components of the system, and will prove to be almost identical to the now banned R12.

It cost me 10 GBP more to re-gass with RS24 but I didn't have to change any components (not yet anyway!). I will keep you all up-to-date with the progress of RS24. I am wondering whether this gas has another name in the states - I will continue my searching.

 

Well I changed the accumulator/evap/drier added two cans of 134a and bingo as cold as eskimo ********* now. Thanks to black89ws6
for the help

 

Hmm, I wish I would have heard of the RS24 before I converted to 134a.

Live and learn .
