2019 Cummins in for a Hamilton camshaft and flat tappet lifter conversion. Customer did it strictly as preventative maintenance due to the common hydraulic lifter failure of the 19+ 6.7s. This kit goes back to the conventional flat tappet lifters, upgraded 3500lb push rods, and adjustable valve train.

Quick weekend job on this lb7. This truck came in with a heavy oil leak which turned out to be from diesel getting into the oil and overfilling the crank case. Tristan & Hunter got it back together with new OEM injectors, injector cups, return lines, seals, and hard lines. While the cabs off we did a motor inspection aswell as a valve lash tune up.

2019 6.7 Cummins with only 102,000 miles and this grid heater was not only completely clogged with soot, but the heater nut failed. The nut on the bottom side circled in red (already broken off this one) over time weakens from heat and vibration. The only place it can go… is right into the cylinder destroying the piston, head, and possibly worse.

If you’re looking to save yourself thousands in motor work, give us a call and schedule an appointment. We always highly recommend going back together with a BANKS Monster ram intake increasing air flow, and eliminating the grid heater nut.

We’ve been nothing but busy for the last couple months so I haven’t had the chance to update with social media. I’ve finally brought on Tristan full time in the shop, so that means turnaround times reduce, and the schedule will open up faster. Big thanks to all my customers who keep me so busy, it’s a good problem to have.

We are still booking out a decent bit, so if you’re looking to get on the schedule sooner than later please reach out via text or call. Diagnostics, upgrades & performance, or general repairs we do anything diesel.
