How We Repair Your Diesel
Systematic approach to diesel diagnosis and repair.
Discuss Symptoms
Tell us what’s happening—loss of power, smoke, hard starting, warning lights, or unusual noises.
Diesel Diagnostics
Factory-level scan tools read all diesel-specific systems including fuel, turbo, and emission controls.
System Testing
Fuel pressure tests, boost pressure checks, compression tests, and hands-on inspection to find the cause.
Clear Explanation
We explain what we found, what it needs, and your options—repair vs. replace, budget vs. premium.
Quality Repair
Using quality parts and proper procedures, we repair your diesel to manufacturer specifications.
Test & Verify
Road test under load confirms the repair is complete and your diesel is running at full power.
Diesel Problems We Fix
These are the diesel issues we see and repair most often.
Fuel Injector Problems
Clogged, leaking, or failed injectors cause rough running, smoke, and poor fuel economy. We test and replace as needed.
Turbocharger Failure
Loss of power, excessive smoke, or turbo noise indicates turbo problems. We diagnose, rebuild, or replace turbos.
DPF & Emission Issues
Clogged DPF, DEF system faults, or EGR problems trigger warning lights and reduce power. We service all emission systems.
Glow Plug & Starting Issues
Hard starting, especially in cooler weather, often indicates glow plug or glow plug module problems.

How Houston Affects Your Diesel
Extreme Heat Load
Diesels generate significant heat. Houston’s climate adds to the stress on cooling systems, turbos, and electronics.
Fuel Contamination
High humidity can introduce moisture into fuel tanks. Water in diesel fuel damages injectors and fuel pumps.
Stop-and-Go Stress
City driving and traffic are hard on diesels. DPF systems need highway driving to regenerate properly.
Oil Degradation
Heat breaks down diesel oil faster. Proper oil service intervals are critical for diesel longevity.
We understand Houston’s challenges to diesel engines and maintain them accordingly.

What Diesel Owners Say
“My Powerstroke was down on power and smoking. Dealer wanted to replace the turbo for $3,500. Race Track found a boost leak—$180 fix. Runs perfect now.”
“Had injector problems on my Duramax. They tested each one, found two bad, and replaced only what was needed. Honest approach saved me money.”
“I run a small fleet of Ram trucks. Race Track handles all our diesel maintenance. They work with our schedule and keep our trucks on the road.”
