anyone have an idea how much compressor oil (total) is needed for a '73. Been totally flushed, new desicant in VIR. isn't it suppose to be distributed between the system, not just through the compressor.

thanks
Ray

11oz is the spec. Usually, you would want to put half in the compressor, and half in the accumulator/dryer. That's gonna be hard to do with the VIR, unless the VIR is still off the car.
Putting all of the oil in the compressor will be fine...the oil will be dispersed thru the system as it runs, and once turned off, the oil will settle to the lowest places in the system, as well as the bottom of the compressor. The VIR is pretty much the lowest component in the system, other than the bottom of the condenser, so the oil will be in just about every place it needs to be.
One other thing you could do is put 1/2 of the oil in the compressor, then evacuate the system. Once you have a good vacuum, you can put the other 1/2 of the oil in thru the high/low pressure hoses on the gauge set...the vacuum will draw the oil into the system on both sides that way. This will only work if you are using a bulk oil, in a bottle. You could also use the pressurized oil in the cans, if you want.

Man, you'll have an all new system (except the evaporator). Should be COOL times ahead!

One thing I noticed on you VIR eliminator kit is the fittings look like they are for R12..would need to remove the needle valve in those and install a retro fit kit..unless you are doing R12.

My first parade at Carlisle 2010

those A-6 compressors leak even when new, changed the seal twice, no luck when I turned on the ac the car would slow down and the temp woud go up, so I pulled the belt and said to heck with it, when I decide to fix it will be  the new style setup and store the original stuff for the new owner.
