11 COMMON 6.6 LLY DURAMAX PROBLEMS AND HOW TO FIX THEM
From dieselresource.com
Estimated Reading Time 9 minsPublished Dec 12, 2020
- Turbo Inlet Manifold. The LLY Duramax utilizes a Garrett variable vane turbocharger (VVT) that has a bigger turbo compressor wheel and taller vanes than other Duramax generations.
- Head Gasket Failure. Head Gasket Failure is more common the LLY Duramax than any other Dmax generation. This is largely due to the huge factory turbocharger and overheating issues caused by a poor cooling system.
- Injector Harness Chafing. As LLY Duramax trucks on the road are only getting older, more and more are being found to have injector harness chafing. Vibrations, heat, and just general wear and tear cause the injector harness to rub against other vehicle components until the wiring gets exposed.
- Water Pump Failure. Water pump failure is a relatively common weak point on Duramax trucks. While the seal issues found on LB7 trucks have been largely solved, the LLY Duramax can still suffer from water pump failure.
- LLY Duramax Overheating. The most notorious problem found on LLY Duramax trucks is that they have a tendency to overheat. Part of this is attributed to their inadequate cooling system, that’s made up of the smallest radiator and fan ever found on a Duramax diesel truck.
- EGR Problems. Like most early emissions devices, the EGR system proved to be a common LLY Duramax problem. The EGR system, or exhaust gas recirculation system lowers emissions by re-introducing exhaust gasses back into the engine.
- Glow Plug Failure. LLY Duramax Glow Plug failure is a common problem amongst late model year trucks. The factory glow plug controllers have been found to overcycle the glow plugs which could result in glow plug damage.
- LLY Duramax Fuel Pressure Relief Valve (FPRV) Problems. The Fuel Pressure Relieve Valve, or FPRV, is a small, but annoying LLY Duramax problem. The FPRV is a plug that utilizes a small spring to relieve fuel rail pressure when it gets too high.
- IFS Suspension/Steering Problems. Like other Duramax generations, the LLY Duramax has an independent front suspension and is susceptible to common problems associated with this front end type.
- Bent Rods. Bent rods aren’t a common LLY Duramax problem unless you modify your truck’s performance. After about 500 horsepower, the factory rods can bend.
