Hi f18pilot5, Welcome to 2carpros and TY for the donation
Might not be a rod knock, an engine that's overheating will create a spark knock/detonation that sounds like a bunch of marbles being thrown into an empty tin can. Is this your case, if so try fixing the crack on the radiator, you're losing coolant and causing the engine to overheat.
