When an Anaheim commercial truck drops power, trips a check-engine light, or starts burning oil, our Yorba Linda technicians find the root cause before anyone reaches for a wrench. We scan live data, run pressure and contribution tests, and grade internal wear, then coordinate any heavy overhaul through our vetted diesel partner network for one straight answer.

Note: We diagnose the fault, remove the engine, and reinstall it in our Yorba Linda shop, and coordinate the heavy internal rebuild through our vetted diesel partner network so your Anaheim fleet keeps one accountable point of contact.

## What this includes
- Complete fault-code scan and live-data capture on Cummins, Detroit, Duramax, Power Stroke, Isuzu, and Hino diesels
- Oil sampling and blow-by measurement to grade internal wear before any teardown decision
- Boost, fuel-rail, and crankcase pressure testing to isolate power-loss and smoke complaints
- Cylinder-contribution and injector-balance checks run under load, not just at idle
- Coolant and oil cross-contamination testing for head gasket and EGR cooler faults
- Written findings with photos and a partner-coordinated overhaul plan you can act on
- Scheduling built around Anaheim and Orange County route demands to hold downtime down

## Who it is for
- Anaheim and Orange County fleets chasing a stubborn power-loss, smoke, or oil-burning complaint
- Owner-operators who need an honest repair-versus-overhaul call before spending on internals
- Managers who want diagnosis and partner-coordinated engine work run through one accountable shop

## Pricing
Diagnostics billed at $285 per hour; heavy overhaul scope is coordinated through our diesel partner network and confirmed in writing after an in-shop assessment.

## FAQ
