Need Advice and New Engine!

[GAHorn]

Hoarding parts that I might need sometime in 15 years is one of my bad habits. If your "new" engine has just been rebuilt (and you can determine from the rebuilder of the lower end that the sump is not compromised already), then the failed engine's sump might be a good item to help you recover expenses. Good sumps are worth fair prices to someone who needs one. (And cleaning/inspection is something you can likely determine yourself.)

Otherwise, you might wish to weigh your out-of-pocket costs of disassembly/inspection ... versus sale-upon-acceptance when selling the rest of the parts. (Let a potential buyer have it inspected at his expense. That way he can be most assured he's getting what he wants, and you can be out less money for parts you'll subsequently be anxious to sell to recoup the additional expense you've inherited.)
