The hoses are probably porous just from age. The AC compressor may be
leaking at the seal and the Condenser or evaporator may be leaking.
Condenser leaks are hard to find but they happen. Also check that the
relief plug on the receiver/dryer is not leaking.

Subject: Air Conditioner Leak

I had my Westy changed over to 134R when it had the engine converted to
a 1.9TD (along with the Jetta Diesel A/C compressor).  No one can find
any leaks but I have lost the charge three times.  Is it possible for
the hoses to leak 134R (because of smaller molecule size of 134R) than
won't be picked up by the light which can detect the dye?  The first
charge lasted a few months, the second charge only 4 or 5 days, and the
third charge about a week.

Thanks
