A conversion to R134A will result in deterioration of all the seal rings in the hose fittings and compressor. These leaks are very small individual and almost impossible to detect, but in concert can bleed the system very fast. Best remedy is to remove ALL black O-ring seals and replace them with

I will second that -- it took three tries to get the AC working on my TE for that very reason -- the 0-rings croaked. Replace the four big ones between the compressor and hose manifold while you're at it, and the ones between hose manifold and hose set. Requires pulling the compressor, but

I was sort of thinking of flushing out the whole system and converting it back to AutoFrost, or even R12. Though I know that the HC refrigerants are NOT good in a leaky system, because the individual component gasses do not bleed off at the same rate, so if you have leaks, you end up with a

Using a normal leak detector you can charge system and let sit for an hour, place detector probe near drain for evap, since Freon is heavier than air the sensor will go off. Other methods used are to place sensor in center vent and turn fan on low. This in my experiences often gives false
