If it's really the original MC the inside is doubtless a gooey mess. For the
amount of trouble involved and considering the possibility of overhoning
creating a poor seal, I would just get a new one. As I recall it is
particularly difficult to disassemble this MC -- there is a plastic
piston-thingie (technical term) that tends to get stuck deep in the bore,
and often has to be drilled or chiseled out.
