The Diesel Playbook is built by Sebastian & Louie (a lead technician with 30+ years diagnosing and repairing heavy-duty diesel trucks) and the team behind LTEK Diagnostics in San Diego.
This is the stuff most techs spend a decade learning the hard way:
→ Diagnostic walkthroughs on the failures that actually show up - VGT actuators, SCR/NOx faults, DPF regens, DEF systems, valve adjustments, aftertreatment
→ Shop operations - pricing, parts procurement, AR management, fleet client acquisition, customer-supplied parts policies
→ Real jobs. Real numbers. Real fixes.
Whether you're a tech sharpening your skills or a shop owner trying to actually run a profitable business - you're in the right place.

For diesel techs and shop owners who want to actually master the work and the business. Diagnostics, repair, and shop ops from 30+ years on the floor.
