How does Duramax exhaust brake work?

Quiet braking using the power of the engine Diesel exhaust braking works by using the power of the engine itself to slow a heavy vehicle. The diesel exhaust braking on the Duramax diesel working with the Allison transmission always delivers the perfect amount of braking no matter the load or the incline.

What are the most common problems with Duramax diesel engines?

The DEF systems on Duramax diesel engines have their fair share of problems also. The most common problems on the DEF systems are the NOx sensors failing. Among the failures on the DEF system are the DEF tank heater and the DEF pump. The DEF fluid level sensor will also commonly fail.

What kind of exhaust system does a Duramax use?

The Magnaflow stainless system comes with a dual-wall 5-inch tip that is computer welded for the perfect fit and finish under this Duramax. Every manufacturer will have its own spin on a high-flow muffler. Some offer internal baffles, some have perforated fiberglass packing, some kits won’t have a muffler at all.

Why does my Duramax diesel engine have bent rods?

The LLY has an EGR system and a variable vane turbocharger. The reason for the change was stricter emissions. The LLY engine has common problems with bent rods. The reason for this is usually caused by enhanced performance modifications on the engine. Modifications to the intake and exhaust systems have an effect on the engine’s tuning.

Why does my Duramax engine take so long to Prime?

It could also be that the o-rings could be worn or damaged. Sometimes the engine could be hard to start. The fuel system will also take longer to prime because of air in the fuel system.

Power was at an all-time high coming in at 397hp and 765 pounds of torque, and in order to provide this much power while still keeping pollutants low, GM needed to be able to increase the pressure in the fuel system to levels above what the tried-and-true CP3 could safely deliver.

What happens to the head gasket on a Duramax?

Head Gaskets – As these truck reach the 100,000-150,000 miles we are seeing more and more head gasket issues. The Duramax has a multi-layer steel head gasket.
