I was most concerned about debris being left inside the compressor. But it doesn't sound like one should actively flush the compressor so I guess you remove, drain, try to get as much oil out as possible and hope for the best.GerryAZ wrote: ↑Sun Apr 24, 2022 7:47 pm I don't think you will have enough oil left in the compressor after pulling vacuum for extended time to worry about. Just use the correct amount for filling an empty system. A little extra oil may slightly reduce the cooling capacity, but probably not noticeable on the LEAF. The main thing is to get the leak repaired and the system fully clean and dry. Are you planning to replace the accumulator? It might be a good idea since the system was open so long. Good luck with your repairs.
After I have it all back together I'll want to pull a vacuum (I'll do it for a long time to boil off any condensation) and then verify it can hold vacuum before recharging.
As for the accumulator, I thought that was only on the model with the Heat Pump.
But to your larger point, the dryer on the Leaf is part of the condenser assembly so I've decided to replace the condenser even if the issue turns out to only be the high pressure pipe. a) I've already bought the replacement condenser b) I suspect after being open so long it needs a new dryer.
Thanks for the help.
