So, Dave, is it migration of lubricant oil that is the problem? Does lubricant
oil migrate into the compressor cylinder and then crack the cylinder because
it is not as compressible as gas? Or is it the coolant that is the problem?


This is Turtle.

Freon will not be in the picture for messing up when laying it on it's side.

Oil will be the problem when laying it on it's side. The oil will travel back
out the compressor through the suction line and drain all the oil out of the
compressor back toward the evaperator coil. When you stand it up for 24 hours
the oil will drain / migrate back to the compressor by way of the return suction
tubing line and put the oil back in the comprssor so it will have the oil to
lube the compressor when it starts. The oil will not drain or flow through the
valves or pistons of the compressor and out the high side line. It just will not
make it out that away for when the compressor is not running the valve will shut
off and oil can't flow that away. It's just too much stuff in it way to travel
that away. Now oil will flow back out the suction line real easy and drain the
compressor.
