How do I know if my injectors are bad on my Duramax?
Symptoms of bad injectors on these would be engine over heating, loud knocking noise(should sound like a bunch of old typewriters), pour acceleration, white smoke emitting from the tail pipe. The easiest way to tell is to pull the oil dip stick and smell for a strong diesel smell in the oil itself.
Is idling bad for a Duramax?
It is true that diesel engines use barely any fuel while idling, far less than a gasoline engine. While it isn’t particularly bad for it, there just isn’t much reason to do it; most diesels start perfectly fine when cold, warm up in a reasonable time, and don’t have gelling issues.
Are there any problems with my 2007 Chevy Duramax?

Are there any problems with the LLY Duramax?
In terms of LLY injector problems, GM had sorted out the internal failures with the 2004 ½ redesign, but the LLY Duramax would occasionally exhibit a trouble code for the injectors, but in most cases it turned out to be an issue with the injector harness rubbing through and causing a short or open in the wiring.
How many versions of the Duramax diesel engine are there?
All told, there are six different iterations of the Duramax diesel engine: LB7, LLY, LBZ, LMM, LML, and L5P spanning from 2001 to the present day. Each version of the engine has its own issues and quirks, and some are less problematic than others.
How often does a Duramax diesel engine leak?
Fluid leaks are important to catch early as running low on fluid can cause catastrophic damage to the transmission. If you are leaking you will notice red fluid dripping from underneath the engine bay. This issue is extremely common and can occur as frequently as every 20,000-30,000 miles.
