I better just calm down and wait to talk to him in person. Fuming on the internet usually leads nowhere.
That is your best bet at this point. If you are rich, you can just throw money at it and problem solved. If you're on a budget like most folks, it's time to take things slow, work with the guy and find out what the problem was. It was either a part problem or human error. If it turns out to be a part problem, he'll have to go after the manufacturer. If it was human error, hopefully he stands tall and rebuilds it properly at his cost.
Have him lay all the parts out on a table when he has it apart and go and inspect them with him. It may take a couple hours, but you should be able to tell if he's BS'ing. If he slaps the thing back together, you may never know what happened.
In the meantime, it won't hurt to do a lot of reading on engine building so you become even more familiar with the terms, measurements, what's important, etc. There's nothing magic in an engine, so the problem should be simple to find.
