That old diesel mechanic set me straight on my torque wrench habits

I used to think you just crank bolts down tight and call it good, never really paid attention to the torque specs on things like intake manifolds or valve covers. About 6 months ago a guy named Frank with 40 years in the trade watched me slam a lower intake on a 5.3 Chevy without even checking the chart. He told me I was basically asking for a blown gasket down the road and that half the comebacks I see are from folks who don't respect the numbers. I argued back that I'd been doing it this way for years with no problems, but he just pointed to a cracked thermostat housing on the bench and said that happens from overtightening. So I finally broke down and started using my torque wrench on every fastener that calls for it, even the little stuff. Honestly it's slowed me down maybe 3 minutes per job but I haven't had a single leak or stripped bolt since. Has anyone else had an old timer call them out on something they thought was fine?

Switched to the same routine and it stopped my coolant leaks dead in their tracks.

Man that's great to hear. Coolant leaks are the worst, I had one on my old truck that drove me nuts for months. Turns out it was a tiny crack in the radiator I kept missing. Glad your new routine sorted it out, nothing worse than seeing that puddle on the driveway in the morning and wondering where it's coming from. Did you just start checking things more often or swap out a specific part?
