System with rear air calls for a total of 11 ounces of oil.

I would say you're pretty close to max performance. You lose about 6 degrees from evap temp to vent temp.

See if the top and bottom lines coming out of the evap case are the same temp.

I got nothing. Could not even find it in Mitchell.

With the equipment you can flush most condensers. Doing a one off job the cost is cheaper to just replace the condenser. http://www.ackits.com/cond-f-series-94- ... 0-319-7626

Having a can checked for purity might be wise. Seems the entire industry has gone China these days.

"I bought a kit to replace them without evacuating the system" really? How does that work and where to find? I've got one leaking on the High side. Cap keeps it in check, but I'd like to replace it so I can use my gauge. Thanks http://www.ackits.com/mastercool-service-tools-and-equipment/...

Non painted are a little thicker and may be just a little bit better constructed. But don;t take that as the painted are a poor condenser. Cost wise I would go with the painted version.

Yes, valve cores need to be removed.
