Warning: My uncle told me to always double-check the torque on injector hold-downs.
He said, 'They'll walk out on you if you don't.' I was rushing a job on a 6.0 Powerstroke last Thursday and skipped the final check. Two days later, the customer was back with a nasty fuel leak. Had to pull the valve cover again and redo it all. Anyone else have a simple step they've learned never to skip?

My old shop foreman swore by a single pass to spec, never had one come back loose.

That final torque check is huge for injector hold-downs, but the sequence matters just as much. Always go in a star pattern and do multiple passes, not just a single crank to spec. It keeps the clamp load even so the injector can't rock and work loose over time.
