OK so i'm going to check out some motors at a local junkyard tomorow. Two LS engines, and a GSR. I'd rather buy from a local source, even if it takes forever to find something. because i like to be able to talk to the person i'm buying from in person, not over the phone. and be able to physically look at the motor before i throw down that much cash on one my question: what are things to look for on a visual inspection. the motors are out of the the cars already, so i cans just run the motor to make sure everything is cool... what do you suggest i look for. no cut hoses, broken sensors, cut wiring harnesses, but what else?
