• Applications: Suitable for Chevrolet Silverado 2500/3500 and GMC Sierra 2500/3500 LB7 engines.

Common LB7 Duramax Injector Failures

The LB7 Duramax is renowned for power and reliability, but suffers a well-documented issue with premature fuel injector failures—often presenting between 100,000–150,000 miles.

Root Causes:

• Original injectors prone to cracking and poor internal sealing.

• Locations under the valve covers complicate service and delay diagnosis.

• Corrosion in injector lines, often leading to repeated failures if not addressed along with injector swaps.

Symptoms of Failing Injectors:

• Hard starts

• Excessive white or black smoke, especially at idle

• Poor fuel economy or power loss

• Rough idle or engine misfire

• Elevated oil level (fuel dilution from injector leak)

• Check Engine Light (CEL) and limp mode

Related Diagnostic Trouble Codes

Faulty LB7 injectors can trigger:

• P0201–P0208: Fuel injector circuit malfunction (individual cylinders)

• P0300: Random/multiple cylinder misfire detected

• P0087: Fuel rail/system pressure too low

GM technical bulletins also highlight oil dilution and rough running as signs to check for injector issues.

Why Choose Alliant Power Remanufactured Injectors?

• OEM Reliability: Leveraging Bosch technology—original equipment in LB7s—for superior factory-matched performance.

• Precision Rebuild: Each injector receives new critical components and is bench-tested for precise spec conformance.

• Long-Term Value: Designed to meet or exceed OE upgraded specs to address previous cohort issues, reducing risk of premature failure.

Maintenance & Prevention Tips

• Always Replace in Sets: If one injector fails on the LB7, others may follow shortly. Replacing the complete bank (or set) minimizes future downtime and ensures consistent performance.

• Replace Contaminated Lines: Change out injector lines with each injector swap to prevent corrosion-related repeat failures.

• Use Quality Fuel & Filters: Poor fuel quality is a leading cause of injector damage—use reputable diesel and change filters at recommended intervals.

• Regular Diagnostics: Monitor for symptoms (smoke, miss, hard starts), check balance rates, inspect for fuel in the oil, and scan for DTCs periodically.
