    forget about pumping it down and taking it apart, charge by superheat first, i would try this before going through all that unless you really want to put in the dryer.

    Yesterday I pumped down the system, blew backwards thru the lineset and ecoil, and inspected the metering pin. I didn't find anything so I pulled a vacuum down to 300 microns and made sure it held for five minutes. Then I released the R22. I doubt I'll be running the AC anymore this year, but if I start it up next year and it makes the same noise, I'll have to figure I already had air in the system.

    Thanks again for all the responses!
