Mobile Engine Repair and Diagnostics in Lynchburg, VA
Engine trouble doesn’t always mean catastrophic failure. But if you ignore it, it just might. We provide on-site engine diagnostics and minor-to-moderate repairs on most heavy-duty diesel engines.
Our mobile engine services include:
- Check engine light and fault code diagnostics
- Injector and sensor replacement
- Glow plug and ignition troubleshooting
- Oil leak identification and basic repairs
- Minor engine component swaps (e.g., EGR, thermostats)
- Engine inspection for PM compliance
While we do not perform full in-frame overhauls or out-of-chassis rebuilds on-site, we offer honest diagnostics and referrals for full conversions or rebuilds if needed.
What About Rebuilds and Overhauls?
When your engine has reached the end of its lifecycle, you have options: repair the damage, rebuild critical components, or replace the engine entirely. We help you evaluate the most cost-effective route, offering:
- Pre-rebuild inspections and recommendations

- Honest advice about rebuild vs. replacement
- Referrals to trusted rebuild specialists if full overhaul is needed

What’s the Difference Between Engine Repair and Rebuild?
Repair focuses on replacing individual faulty components (like injectors or sensors). A rebuild involves replacing or machining major internals—pistons, crankshaft, and bearings—typically when the engine reaches end-of-life or suffers major failure.
Can You Rebuild an Engine On-Site?
No. Full overhauls or out-of-frame rebuilds must be done in a shop. However, we can provide diagnostics, recommendations, and trusted referrals to rebuild facilities.
