Corvette A/C rebuild

[ChrisLorenz]

I am redoing the A/C on my 1994 Corvette (134a). It had a leak in the evaporator so I replaced that and the dryer. I also flushed the complete system and drained all the old oil out of the old compressor (Denso 10PA). From the research I found that is takes 8oz of Pag150 oil (?). my question is since the complete system is dry do I ad all 8oz of oil to the compressor or should I add 4 oz to the compressor and then so to each of the other parts (evap, dryer, cond,)? Also does it mater what port (line) I add the oil to in the compressor?
thanks

Add 80% to the compressor via the suction port. 20% to the accumulator.

Thanks for the help. Is there a way to tell which post is the suction side?
thanks

the hose that goes to the condenser is the high side

the hose that goes to the condenser is the high side

The hose that comes from the evaporator and accumulator is the low pressure side.

Add the refrigeration oil, then turn the compressor (not just the compressor pulley) through at least 10 revolutions with a wrench before evacuating and adding refrigerant. Do NOT add any sealant, just refrigerant, and some UV dye if you desire.

The refrigerant will actually carry/distribute the oil through the system once it's all going.
