Michael,
Thanks for the bigger picture. I will consider my compressor trashed first, then see if it is salvageable. I am very close to selling this car, oh as much as I love to drive it does not hold well baby three comming third car seat well. We don't like kids in the very back rear facing... Thanks to my neighbor for selling me the 190e a few years back. I am so hooked on MB!

It is a wagon w/100+K miles and it is an oem compressor that has lived its life in California and Florida and now a bit in Texas. I bet unless Cali was really nice on it, the unit is wore out from the additional cooling load of the wagon's interior space, albeit w/tinted windows its whole life.

Between mastercool and the vendors linked to aircondition.com, where is the o-ring kit; did you get yours from a Toyota dealer?

Can I micrometer the pistons and walls, OR just go by wall scratches?

I see Japan rebuild is a good source, What company in USA or Japan for a good rebuild, one that stocks them all the time? Toyota dealer?

I like the idea of 134a condensor with R12 running through it!
These fans make a lot of noise as it is, way more than the 190e fans that cooled 134a convert pretty well down to ~42*F on a 80*F minimal sun day.

Thanks million for the thoughts,
Blessings from Brian
