What causes the LLY Duramax Turbo mouthpiece to choke?
What causes the LLY Duramax Turbo mouthpiece to choke?
The LLY Duramax turbo air inlet manifold, sometimes called the turbo mouthpiece, forces the turbocharger to work harder than it needs to. It does this by essentially choking the turbo because of its small, restrictive design, forcing it to work harder to produce the same amount of boost. This results in excess heat and EGTs.
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.
What causes a Duramax diesel truck to overheat?
Its restrictions cause excess heat and force the turbocharger to work harder than necessary. The LLY experiences more overheating compared to other generations of the Duramax diesel because of its inadequate cooling system. They have the smallest radiators and fans found on any Duramax diesel truck.
What kind of truck has a Duramax engine?
In the United States, you’ll primarily see Duramax engines in Chevys and GMCs. If you head overseas, you’ll see the same engine in the GM owned Isuzu brand. The Silverado, Colorado, Sierra, and Canyon are the most common vehicles to have Duramax diesel engines – but you’ll also find Duramax engines in Chevy Express vans and the GMC Savana.

What kind of transmission does a Duramax diesel use?
It was the first to come bolted to the six-speed Allison transmission which provides a lower cruising RPM and greater fuel efficiency when compared to the five-speed on the LB7 and LLY.
