Thanks for the input starfighter. From what I can tell there is a common problem with tephlon coated rings in these compressors. Sometimes when they fail they coat the entire system with the tephlon, burned oil, and aluminum. The coating hardens up and is sometimes not affected when flushed. It then becomes mobile again when the system heats up, thus relocking the system.
I got this from the do it your self section on A/C control diagnostics from this website.
