Why is my Duramax diesel engine not working?
The trucks computer keeps track of how much fuel needs to be added or subtracted from each individual cylinder to make the engine run smoothly, and this value is called the balance rate. If one cylinder is contributing too much or not as much as the rest, the cause is usually a bad injector and the cure is a replacement.
Are there any problems with the Duramax LMM?
One problem can rear its head when you are pushing the power of the LMM to a level GM never imagined, and that’s with the pistons. Simply put, they can crack under pressure. There are a lot of factors which dictate the power level where a piston bites the dust, but it’s usually north of 600 horsepower.

When do Def warnings start on a GMC 2500?
The Engine Control Module (ECM) monitors the DEF level and consumption rate in order to calculate an estimated range in miles remaining until the DEF reservoir is empty. DEF levels are detected by the 3-position solid-state DEF level sensor. Typically, DEF warnings begin once the estimated mileage falls below 1,609 km (1,000 mi).
