Your upside down drier is a big problem. The AC system has to carry the
compressor oil throughout the system and return it to the compressor. The
oil can not pass through the desiccant material in the drier. The drier has
a hole at the bottom of the element for the oil to drip through so that the
freon can carry it through the evaporator and back to the compressor.
Obviously, with the Dryer upside down, this will not work properly. The
Dryer is possibly destroyed now and hopefully the pieces are not cogging the
expansion valve or destroying the compressor.

The dudes at the local A/C shop put 3 cans of R134 in my system and called
it quits.  It beats having window down, but it's not even close to what I've
seen on this list so far.  The compressor is whining worse than my x-wife
with cramps.  I don't think they put enough R134 in it.  They also told me I
have a leak in the system.  Well, after two months I haven't seen any
reduced cooling efficiency.  I also have the '86-up drier mounted
upside-down because it would not fit any other way and I think that maybe
hurting the system performance.  I have not replaced the expansion valve
either.
