DIAGNOSTICS
FIRST
Comprehensive diesel engine diagnostics help you understand exactly what's wrong, what needs to be fixed, and what it will cost—before committing to a rebuild.
WHY DIAGNOSTICS MATTER
Not every engine problem requires a complete rebuild. Sometimes a simpler repair can solve the issue and save you thousands of dollars. Proper diagnostics help identify the root cause and determine the most cost-effective solution.
Even when a rebuild is necessary, diagnostics reveal the extent of damage, help us provide accurate quotes, and ensure we address all issues—not just the obvious symptoms.
FIND ROOT CAUSE
Identify the actual problem, not just symptoms. Avoid unnecessary work.
ACCURATE QUOTES
Know exactly what needs repair and what it will cost before starting work.
RIGHT SOLUTION
Determine if you need in-frame, complete rebuild, or simpler repair.
OUR DIAGNOSTIC PROCESS
1. VISUAL INSPECTION & HISTORY
We start by examining the engine for obvious leaks, damage, or wear. We also review maintenance history, operating conditions, and symptoms you've experienced.
2. COMPRESSION & LEAK-DOWN TESTING
Compression and leak-down tests reveal the condition of cylinders, rings, valves, and head gaskets. These tests are critical for determining if a rebuild is needed and what type.
3. OIL ANALYSIS & FLUID INSPECTION
Oil and coolant analysis can reveal internal wear, contamination, and potential failure points before they become catastrophic.
4. PERFORMANCE & ELECTRONIC DIAGNOSTICS
Modern diesel engines have sophisticated electronic controls. We scan for codes, monitor live data, and test sensors to identify electronic or fuel system issues.
