The diesel injectors used in the Duramax diesel engine are electronically controlled and are more reliable than ever. But like nearly every other part of your truck, your diesel injectors are working hard all the time and can become worn and weak over time.
Duramax Diesel Injectors from Sinister Diesel
The two main reasons Duramax injectors fail are every day wear-and-tear and contaminants in low quality fuel. Most Chevy or GMC diesels have a deserved reputation for being long-lived workhorses and it’s not hard to find one running strong with well over 200,000 miles. But the engine bay is a harsh place and even on a well-maintained truck, the wear of hundreds of thousands of miles on the precision components inside diesel injectors can add up. Poor fuel quality or poor filtration can score the seating surfaces inside the injector body, compromising the seal and causing leaks. Similarly, a cracked injector won’t allow the fuel rail to reach adequate pressure resulting in a loss of power, poor running, increased crank times, and excessive fuel consumption.
