Not necessarily. Lots of things hold on to water at that temperature by
virtue of hydration energy. This is one reason you need a dessicant in the
system to start with. Water is tenacious and wonderfully hard to get out
of things. The "universal solvent" would rather stay dissolved.

The time or place may come where you have no option.

Please tell me where you can get an accumulator with installation for $20.

The vapor pressure on steam is pretty high and the surface tension of
the oil at that temp is pretty low so oil would not hold it in. In R12
system they used desicant to keep mosture out primarily to prevent ice
crystals from blocking orifce. On a R134 system, water reacts with
R134 and forms a acid which eats aluminum so it is kinda REALLY
important with a R134 system.
