A new drier was installed. Everything looked ok. Second technician found what looked like a complete blockage from the new filter back into the condensor with oil. Second scroll installed like the first with a new filter/drier & started up without problems. Only thing noticed was how it was transported & handled.

Also the filter/drier appeared to block all (or virtually all) liquid oil. No drops of oil showed above the filter when it was removed. So the filter did appear to cause a blockage due to the liquid oil.

What is the consensus on how to handle the scroll, should it be kept upright even during transportation?

If oil does come out of the outlet when the plug is removed, or it is somehow pumped out, how does one properly determine that the compressor has a proper amount of oil?
