Thanks for the advice.

I spoke to my mechanic and he insists that removing the compressor is overkill. He wants to clean out the system through use of compressed nitrogen. No mention of flushing with solvent.

Additionally, he said that polyolester (sp?) oil is compatible with both R134 and R12, thus no need for concern.

I can't talk him into flushing it as you suggested, Larry.

Now what? Find another mechanic?

I'd just do it myself if I had all of the equipment, since no one else wants to follow directions...
