scammed by mechanics, please help

In a boosted car, if the car doesn't have the right knock fighting octane etc, you can blow a piston to pieces. Those pieces have to go down through the rotating assembly .. typically they lodge themselves between the block and say a connecting rod. Presto, engine locked up.

It is possible for the piston to pass, but not likely. So here's pictures of that near impossible thing happening.

Something missing?

Owwwie

Here's the piston, in the oil pan

funniest part was when I lifted the hood to buy the car, it sat all winter ~6 months. I said, "um where's the valve covers?" They were in the trunk...of course..lol

I've been around boosted cars for the last 10 years, owned about 15 turbo cars, but only one supercharged car (Cobalt). I know about detonation and melting pistons. The first time I melted a hole in a piston it was in a 90 Eclipse GSX, and the car actually still ran, just sounded like a weed eater.

If she said she heard metallic noises and lost power, I would say there is engine problems. But squealing and losing power I don't get.
