Help! RV2 compressor blew new shaft seal

static pressure could easily be 2 to 3 times the running pressure on the suction side. .

I realize......and of course when off but with high underhood pressure.........what I was getting at is that too much oil or refrigerant should not be the cause, and pressure is "connected" IE the crankcase should not be an isolate trap of some sort. Not sure "flooding it with oil" should matter that much. Surely that oil is REALLY slung around in there. There is oil throughout the system.
