The newer refrigerant leak stoppers are actually really good. They stay suspended with the PAG oil until they come in contact with a major pressure change to atmospheric pressure (0 psig).

The only thing is if you keep on charging your system with it, it will reduce the amount of refrigerant your system can hold and then your air will stop blowing as cold due to the fact you have less heat transfer capability from your evaporator to condenser.

 

Regardless its a temporary solution. You couldnt imagine how many compressors and accumulators i've seen ruined by the stuff.

 

The only way a receiver would be destroyed is by a leak that let moisture/air and non condensables into the system. This would exhaust the desiccant and cause the compressor to seize. Not the actual sealant.

 

Man................. You gotta love these forums... I love getting the mixed opinions. I will recheck it again tomorrow and in a few days, just to satisfy me. Honestly, right now, I cant spend much more on getting this fixed again and again.

Thanks again for all the help and suggestions.

 

So you've never come across receivers, as you call it, that have literally "sludged" up with sealant forcing the oil to places it shouldn't be...like locking a compressor, or a line and popping seals?

 

I have checked the system again and it has leaked down again. It had 18 pounds of pressure in it when I checked it yesterday, from 25. I then took it back to the shop where it it was last repaired, and they also couldnt find the leak. They told me to bring it back when it didnt blow cold anymore. I thought for sure they needed it to blow cold to help find the leak, due to the high pressure in the system, not when it hardly has any in it? Am I understanding this right? This is really freaking pissing me off.

I did contact the first person who worked on it, and they did change all the orings when converted to 134a.. I have no idea what else to do. I am tired of wasting money on freon, and still cant find the leak.

Anybody else got any thoughts, just getting frustrated about this, and it aint getting cooler in Alabama.

 

Pop a hose off and check those orings yourself, specifically the orings on the revolution sensor for the compressor and where the hard lines meet the condenser/accumulator

You have a fairly large leak, red dye in the oil with a little more oil and pressure than the system calls for should quickly make the grimmelin show. (it did on my SC, an oring on the revolution sensor that leaked when it wanted to.) A few psi higher in the system and an ounce more oil than it should have and it skeeted oil out of the leak. It was easy to find then.....but i would only recommend this as last resort. You COULD damage something else doing this, but the high pressure will almost always only attack the weak link.

 

Nope, never seen it that bad. As long as you don't continually charge your system with it, I don't see why that would happen. When I work on R-114, R-32, R-542 and R-12 systems (namely R-114 and R-12 as that's what on the sub) we use similar stuff in leak diagnostic/small leak repair without having to rip apart the miles of piping that makes up one R-114 (200 ton cooling capacity).

A couple of years ago, we had a leak on #2 R-114 that resulted in the loss of 285 pounds of charge (full charge is 825 pounds) over the course of 8 months. We recovered the charge, replaced the desiccant, drew down a vacuum on the system, recharged it with a small amount of this sealant and haven't lost a single pound of charge since. The stuff works, but the idiots that don't know how to use it give it a bad name.

 

Update... Found the leak.. It was around the front of the compressor around the clutch. It had finally slung some dye around it and the inside of the car to where I could see it finally. I have ordered a OEM factory Denso compressor this time.. Should have done this the first time, but its so much money! Will keep everyone posted. Thanks for your help fella's.

The company where I ordered the first 2 compressord from, sold me the OEM Denso w/clutch at cost with free shipping. The total was 695.00. I thought this was a steal considering the local dealer was over 1200. They are also warranting it for 3 years instead of 30 days from dealer.
