Talking to an old timer at the truck stop in Flagstaff changed how I see diesel work

Honestly, I was just grabbing coffee and this guy, maybe 70, saw my shop shirt and started talking. He worked on big rigs for forty years, mostly on the old two stroke Detroits. I was complaining about chasing a phantom knock on a 6.7 Powerstroke for three days. He just smiled and said, 'Kid, you're listening for the problem. You gotta listen to what the engine is trying to tell you it needs.' Ngl, that hit different. I've always been so focused on the code reader and the specs, but he meant listening to the whole sound, the rhythm, the feel. I went back and just sat with the truck running for ten minutes, no tools, and I swear I heard a tiny puff in the exhaust note I'd missed before. It led me right to a cracked up pipe flange. Has anyone else had a simple piece of advice from an old hand totally shift your approach on a job?

Forty years on two stroke Detroits is wild!

Actually, those two-stroke Detroits are still running in some places (like ferries).
