The most common item that leaks is the evaporator. it has to withstand the rigors of constantly flexing.. Next on the list is the shaft seal on the compressor and lastly is the O-rings and condenser.

Chris989, You've been at this leak for a year, have you conducted a diligent search for the leak.. Dyes, guessing, and throwing parts will not meet with much success.. Get one of those leak detectors and then PM me and I'll explain how to use it.

I have a fieldpiece detetor,,, I use it some things, it is nice, but it only work when you can reach places.


I should have replaced the evap when i did the entire system,,, What was driving me nuts was the fact it could hold nitrogen forever and not loose any PSI. My guess is the change in temp was enought to open the void and let the gas leak out???

When i did the converson,, i even isolated the evap and charged with nitrogen,, it did not leak.
