I'm back after a long absence. Thanks again for all the help and advise.
After six years, the rebuilt compressor I installed finally blew a seal. The compressor was noisy for around 18 months or so before it gave it up last fall.
I want to convert the system to R-134a (the right way, of course) and I was wondering how much oil I need to add to each component after system flushing. The factory shop manual gives quantities of oil to add, but these amounts are for systems that had not experienced rapid refrigerant leakage. After disassembly and flushing, I'm going to be starting with an essentially "dry" system so I would think the quantities specified in the FSM do not apply. Can some one give me some guidance?
I really don't trust that the quantity of oil that are in the components now are a true measure (no pun intended) of the quantity of oil that NEEDS to be in there; I just cannot trust the work of the shop that FUBAR'ed the repair in the first place (see link).
BTW, the FSM states that the system holds a total of 9.0oz of oil, if this info is of any help.

9 ounces of oil is the mfg suggested capacity for this vehicle. 2/3rds in the compressor and 1/3rd in the accumulator is what I would suggest.
Thank you very much for the input.
