Turbocharger
Repair
VGT actuator service, turbo rebuild, replacement, and turbo compound repair for all diesel engine platforms. Diagnosis-first approach that saves you money.
Turbocharger Repair Experts
Modern diesel turbochargers — especially Variable Geometry Turbos (VGTs) — are precision components that require specialized knowledge and OEM diagnostic tools to service correctly. A misdiagnosis can mean replacing a $4,000 turbo when the actual problem was a $900 actuator.
CTR's diagnosis-first approach uses OEM scan tools, boost pressure testing, shaft play measurement, and borescope inspection to identify the exact failure before recommending repair. We service all turbo platforms — Holset, BorgWarner, Garrett — on every major diesel engine.
Located on Armentrout Drive directly off I-85 at Exit 58. All turbo repairs backed by our 3-year, 36,000-mile warranty.

Turbo Warning Signs
Loss of Power Under Load
Engine cannot reach rated boost — sluggish acceleration and reduced pulling power.
Excessive Black Smoke
Insufficient air from failing turbo causes incomplete combustion.
Grinding or Metallic Sound
Shaft bearing failure allowing wheel-to-housing contact — SHUT DOWN IMMEDIATELY.
Blue/Gray Smoke
Oil burning from turbo seal failure, allowing oil into intake or exhaust stream.
Turbo Boost Fault Codes
Underboost or overboost conditions logged by the ECM. VGT actuator position faults.
Oil in Intake Piping
Downstream of turbo compressor outlet — compressor-side seal failure.

Understanding Turbo Systems
A failing turbo doesn't just reduce power — it can cascade into engine damage, aftertreatment contamination, and exponentially higher repair costs. Early diagnosis and proper repair prevents these expensive secondary failures.
VGT Technology
Variable Geometry Turbos use movable vanes to optimize boost at every RPM. The electronic actuator is the most common failure point — sticking vanes from carbon deposits are second.
Oil System Is Critical
Turbo bearings spin at 100,000+ RPM on a thin film of oil. Restricted supply lines, drain restrictions, or poor oil quality cause the majority of turbo bearing failures.
Turbo-Aftertreatment Connection
Poor turbo performance = higher soot = DPF overload. Oil seal leaks contaminate DOC and DPF. VGT issues affect exhaust temperature management for regeneration.
Diagnosis Saves Money
A $900 VGT actuator replacement vs. a $4,000 turbo replacement. Accurate diagnosis using OEM tools identifies the actual failure — not just the symptom.
Built for Heavy Duty
CTR's facility on Armentrout Drive has the OEM diagnostic equipment, turbo service tools, and bay space for complete turbocharger diagnosis and repair on any commercial diesel engine.
Diagnosis-First Approach
We use OEM scan tools, boost pressure testing, shaft play measurement, and borescope inspection to identify the exact turbo failure before recommending repair. No guessing, no unnecessary replacements.
