I couldn't find a pan gasket in the ASA program either, so that may end up being a "make your own" type of deal. T-stat is listed as a "kit" so I'm assuming it would include a gasket. O-rings I have listed above. The intake and exhaust valve seals are now one part number from what I've read, and the parts listing in the ASA. I have that part number listed above as well. But again, double check me. I'm the FNG.

EDIT: I'm seeing $3.85 each on the valve seals on mitsubishiparts.net.
