The LB7 Duramax Diesel Trucks

2001 brought the introduction of the 6.6L Duramax diesel as an LB7 platform.  These trucks are known for their excellent mileage, easy modifications, and no emissions equipment.  The LB7 Duramax trucks are both fun and affordable!

Common LB7 Duramax Problems

Exhaust haze at idle is by far the most common complaint among LB7 owners.  These problems are almost certainly caused by worn/leaking injectors.  As the injectors wear they cause excessive fuel quantity to enter the cylinder and can't be fully burned, especially at an idle.  Once under load this excessive fuel is generally able to be consumed and little to no driving concerns are noted other than the haze at idle.
