Used to just eyeball valve lash on our fleet's 6.7 Cummins, but after a rough idle on unit #7 last month, I started using a go/no-go feeler gauge set.
The old way was fast but inconsistent, and we had one injector rocker arm get way too loose over 15,000 miles. Now I check every 10k with the gauges and torque to spec, which takes an extra 20 minutes per engine. Do you think the extra time is worth it for preventative maintenance on high-mileage rigs?

Ever tried to eyeball something and ended up with a face full of diesel, or is that just me?

Consider the cost of a tow and a road call versus that twenty minutes. You're not just saving an injector, you're keeping the truck earning money on the road. That extra time pays for itself the first time you avoid a breakdown.
