Stop in for a cup of coffee

Just got home from a trip that took 6 hours instead of 4 to look at a truck. Told the guy I heard a rod knock and he said no, jumped in and gunned it to redline half dozen times. We all know what it sounded like after that.
Clatter, clatter, rumble rattle, boom, boom, boom....like a big bag of rocks rolling down a flight of steps.
