A guy at the truck stop in Tulsa mentioned checking injector lash every 15k and it got me thinking
I was grabbing coffee at a truck stop outside Tulsa two weeks ago and overheard two old guys talking about a 6.7 Cummins that was running rough. One of them said he checks injector lash every 15k miles, not just when the motor starts clacking. I've always gone by ear and waited until something felt off, but hearing him say that made me wonder if I'm missing stuff early. My truck just rolled 180k last month and I've never touched the lash, so now I'm second guessing myself. Is that 15k number realistic on a daily driver, or was that guy just maintaining a fleet truck? Curious if anyone here sticks to an interval or just waits for symptoms.

That "not just when the motor starts clacking" line hits home because I did the exact same thing, just waited for symptoms and ignored it until my truck started running rough around 160k and it turned out the lash was way off. Now I check mine every oil change and honestly it runs smoother than it ever did before.
