Ok Gang... I need to pick someones brain... I've got a pretty good leak in the A/C system for it to leak out all pressure to 0 PSI in about 2 weeks. I've got a dye pack in the system but haven't noticed the green tint oil anywhere yet. I'm thinking of grabbing a single can of R134a and add it to the system for pressure and black light the whole thing again... Any ideas or suggestions?

Why do you need A/C in Idaho? You will be working on covering your grille soon enough.

Ummm... Like today it was 88-90*F it nice to have it when it is hot... Trust me... I'll be much happier when the temps fall to around 20-40*F... (Ahh...)

I like to leak test with nitrogen, and you could mix some referigerant with it too. And then do leak test electronically or with bubbles. I like the dye, but it can be blown around with the oil. Then you put black light on it and its all over.

Funny part is with the UV dye I've got in the system it shows up like a sore thumb without a doubt... But in all the times I check the system I never found any leaking out... :banghead:

That is why, I like Nitrogen and soap bubbles. Also nitrogen can be used to sweep out a system of junk, when the lines are disconnected.

Can Nitrogen be purchased in aerosol cans, for backyard mechanic use?

never heard of that done considering the youngsters start huffing it. only places to get nitrogen are licensed gas supply shops as far as i am aware, plus a aerosol can will not be able to pressurize a system like this to 150 psi+
