THE 5 MOST COMMON LB7 DURAMAX ENGINE PROBLEMS - 6.6L V8 DIESEL

From chevytrucks.org
Estimated Reading Time 9 mins
  • LB7 Fuel Injector Failure. The LB7 utilizes direct injection which means that fuel is injected directly into the cylinders rather than into the intake manifold where it is then routed to the cylinders.
  • Water Pump Failure – LB7 Duramax. Water pump failure is common across just about every Duramax out there. Unlike the LBZ water pump failure which is caused by the impeller being made of plastic, the LB7’s issues are caused by the coolant side seal on the water pump.
  • Fuel Filter Housing O-Ring Leaks. The LB7 uses an injection pump, or high pressure fuel pump, to send fuel from the gas tank to the fuel injectors. As part of the fueling system you have a fuel filter and filter head which filters fuel before the fuel is sent through the lines to the injectors.
  • Blown Head Gasket. Head gaskets are common failure points on the LB7 for a variety of reasons. As we’ll get into with the next problem, these engines are known to occasionally overheat while towing.
  • Overheating Duramax LB7. Another commonly reported problem is the LB7 frequently overheating while towing heavy loads. While overheating can also be caused by a bad water pump, this overheating is mostly thought to be from a faulty fan clutch.


THE 6 MOST COMMON LLY DURAMAX ENGINE PROBLEMS - 6.6L TURBO ...

From chevytrucks.org
Estimated Reading Time 9 mins
  • LLY Bent Rods. While the LLY made competitive performance numbers back in 2004, the engine is certainly not competitive to the modern day diesels. For this reason, adding performance modifications to the Duramax is a common route to improve performance and hauling capacity.
  • Head Gasket Failure – LLY Duramax. The LLY has the largest turbo in it out of any other 6.6L Duramax variants. Outside of it being the largest turbo, it had the largest compressor wheel and the tallest exhaust vanes.
  • EGR Valve Failure. Unfortunately, exhaust gas circulation (EGR) systems were standard on every Duramax LLY produced. The EGR system included a EGR valve and cooler.
  • Glow Plug Failue – 2006 LLY Duramax. In 2006, the glow plugs were paired with a problematic glow plug module. At 6.6 liters, these engines (and all other diesels) are big hunks of metal.
  • Overheating in Pre-2006 Models. In the head gasket failure section above we discussed how the LLY diesel is subject to high heat levels due to the turbocharger and design of the turbo inlet.
  • Fuel Pressure Relief Valve. The fuel rail on the 6.6L Duramax injects fuel at nearly 23,000-26,000psi of pressure. Included on the fuel rail is a pressure relief valve which is a spring-loaded valve on the back side of the fuel rail.


5 FATAL FLAWS OF THE DURAMAX—AND HOW TO FIX THEM | …

From drivingline.com
  • Snapped Crankshaft. Perhaps the most devastating of all Duramax failures is a broken factory crankshaft. Not only does this mean game-over for the engine, but it results in a truck that’s down for weeks (if not months) and a huge chunk of change missing from your wallet.
  • CP4 Failure. This one is specific to the LML code Duramax produced between ’11-’16, which used the Bosch CP4.2 high-pressure fuel pump (vs. the predecessor CP3 found on LB7, LLY, LBZ and LMM engines).
  • Bent Rod(s)—LB7/LLY. We’ll be honest, experiencing a tweaked connecting rod in an LB7 Duramax (’01-‘04) or LLY Duramax (’04.5-’05.5) is almost exclusively reserved for engines making double the factory horsepower (or more).
  • Cracked Piston(s)—LBZ/LMM. Even though the ’06-’10 Duramax's are equipped with slightly stronger, forged-steel rods than what was used in the ’01-’05 engines (LB7 and LLY), the problem moves upward, into the pistons, on the LBZ and LMM engines.
  • Leaking Injectors—LB7. One thing the ’01-’04 LB7 Duramax is notorious for is injector failure. The two primary failure points of the factory injectors are internal cracking of the injector body itself and corrosion-induced failure of the internal ball seat.


WHAT ARE COMMON MECHANICAL PROBLEMS WITH CHEVY DIESEL TRUCKS?
Chevrolet diesel trucks use the 6.6 liter Duramax engine, which is prone to intermittent fuel starvation, water pump failure, overheating, injector failure and injector harness chafing. These trucks also use Allison 1000 transmissions, which commonly slips into limp mode when not necessary. The Duramax engine’s design allows air to enter the fuel lines in certain …
