I know paying $200.00 for probably nothing besides for a tow sucks at this time of year, and you're moving to boot. However it's a relatively cheap lesson learned, and could've be worse. I saw one guy put the throttle down on a car until it blew up because a customer didn't do what he wanted, and some other things. Take a good look around the truck in, and out for any damage done. I'm sorry to be so negative, but this guy doesn't seem to be the cooperative type. Notify the mechanic this vehicle is taken to when this motor comes apart I'd look for the pieces of timing parts, and anything else that may have been put in there. He probably knows the other guy, and might have an idea if he's the type to do something like this. I wish I was close by I'd help you out personally I hate when people in my field make us all look bad. I hope this turns out ok, the move goes smoothly, and you enjoy the rest of your holiday season.
