Is the lly a good Duramax engine?
The 2nd generation Duramax is known as the LLY. Similar to the LB7, the LLY Duramax is reliable, powerful, and lacks most of the emissions found on modern day diesel trucks like the L5P. LLY Duramax trucks don’t suffer from the same injector failure problems that LB7 trucks frequently had.
What problems do the LLY Duramax have?
The most common issues LLY owners encounter include decreased fuel mileage, overheating and poor turbo response. These symptoms result from the inlet mouthpiece of the Garrett turbocharger having to fit into a smaller engine space.
How long will a LLY Duramax last?
The Duramax engine should last up to 300,000 miles before needing major repairs if you are wondering how long it will last. The number of miles an engine can run depends on how well it was maintained and driven over its lifetime.

Is LLY better than LB7?

The power is dormant right off idle until the turbo spools, then it takes off like a rocket.
