At By The Book Diesel & Auto Repair, we focus on the engines that keep your work, towing, and daily driving on track. Whether you drive a Powerstroke, Duramax, or Cummins, our technicians understand the systems that make your diesel perform and the failures that commonly affect each platform.


We use advanced diagnostic tools designed specifically for modern diesel technology, allowing us to evaluate injection pressure, turbo performance, emissions systems, fuel trims, DPF status, and sensor data with accuracy.

Routine maintenance is essential for any diesel engine, and our services include oil and filter changes, fuel filter replacements, cooling system inspections, and turbo system checks to prevent early wear and expensive failures. We also handle specialized repairs such as injection pump replacement, injector testing, glow plug systems, head gasket diagnosis, and high-pressure fuel system troubleshooting.
