Even though the LB7 turbo is generally sound, issues can arise as time goes on. While this generation of the Duramax turbo should have 20 psi of maximum boost, a lack of boost can be the symptom of many problems. For example, oil can coke inside the turbo and cause premature failure, and the compressor wheel can stop functioning, requiring a full rebuild of the turbo. The LB7 may also need to be replaced or upgraded to help maintain the correct air to fuel ratio for the engine.

Shop everything you need to upgrade or extend the life of your 2001-2004 Duramax. ProSource Diesel can help you find the right LB7 turbo rebuild kit, up pipes, and more.
