The L96 is a heavy-duty workhorse engine. Variable valve timing helps the 6. Intake flow was improved over previous engines by straightening out and optimizing the flow path from the intake manifold into the cylinder heads, while the exhaust ports are also designed for greater flow.
Quiet features built into the engine are complemented by an improved engine cradle and mounting system. These help reduce vibrations transmitted through the chassis and into the passenger compartment. Its deep-skirt design helps maximize strength and minimize vibration.

A structural oil pan further stiffens the powertrain. The L96 6. The chain, which connects the camshaft and crankshaft, is validated formiles of operation and fitted with a leaf-spring-type dampener. The intake ports that feed the combustion chambers, as well as the D-shaped exhaust ports, are designed for excellent high-rpm airflow.
Camshaft Phasing : the L96 features variable valve timing, maximizing engine performance for given demands and conditions. At idle, for example, the cam is at the full advanced position, allowing exceptionally smooth idling. Under other conditions, the phaser adjusts to deliver optimal valve timing for performance, drivability and fuel economy.
Under light loads, it can retard timing at all engine speeds to improve fuel economy. E85 Flex-Fuel Capability : E85 is a clean-burning, domestically produced fuel composed of 85 percent ethanol alcohol and 15 percent gasoline.
Ethanol is renewable and produces fewer emissions in the combustion process. It can be produced from various feed stocks, including corn and wheat stalks, forestry and agricultural waste and even municipal waste. Advanced Electronic Throttle Control : with ETC, there is no mechanical link between the accelerator pedal and the throttle body. A sensor at the pedal measures pedal angle and sends a signal to the engine control module ECMwhich in turn directs an electric motor to open the throttle at the appropriate rate and angle.
The ETC system can deliver outstanding throttle response and greater reliability than a mechanical connection. Quiet Exhaust Manifolds : the exhaust manifolds were developed to improve durability and sealing and reduce operational noise.
Cast nodular iron was the material of choice for its basic durability and excellent heat-management properties. The manifolds are fitted with new triple-layer heat shields fabricated from stainless steel and insulating material. The shields limit heat transfer from the engine to the engine bay, allowing the 6. This allows the engine control module to adjust ignition timing with greater precision, which optimizes performance and economy.
Engine starting is also more consistent in all operating conditions. GM Authority Newsletter Subscribe for free to receive our daily newsletter in your inbox.Article may contain affiliate links.

Primary changes to the Gen IV were block modifications to enable displacement on demand as well as designs to enable variable valve timing. The Gen III version of the 6. The LQ4 was designed to provide great durability. The LQ9 is a very similar engine based on the LQ4, but it was developed specifically for the Cadillac Escalade, although this version was also added to certain GMC and Chevrolet full-size pickup models as well.
One of the distinguishing features was the increased compression ratio for the LQ9, enabled by a different piston design. The first Gen IV version of the 6. The L76 essentially replaced the LQ9, and it offered the displacement on demand technology, as well as the variable cam phasing.
This engine was eventually phased out in The LY6 was very similar to the L76, but primarily developed for heavy-duty trucks, and the LY6 is still an option for these heavy duty pickups. This engine was very popular for its power and towing ability, particularly for a gasoline engine, as well as its durability. The major negative comment for most owners was related to fuel consumption associated with this engine. These engines had a bore of 4.
A couple of model years of the Gen III engine used cast iron head, but after that the engine switched to aluminum alloy cylinder head. The Gen III block was constructed from cast iron for the entirety of its availability.
The LY6, which was a very similar engine but used in the heavier duty applications, used a cast iron block. Both engines used traditional overhead valve OHV design with 2 valves per cylinder, driven by a traditional camshaft in block design.
This engine is well known for having plenty of power and providing good performance in heavy load, but it is also known for its high fuel consumption. Overall, customers are generally happy with the performance and durability of this engine.
Head and Block Construction A couple of model years of the Gen III engine used cast iron head, but after that the engine switched to aluminum alloy cylinder head.
Conclusion The 6.The General Motors 4. There were a handful of different 4. The primary difference between the two is that the 5. An early version of the 4. The LY2 version, which is the generation IV of the small block GM engines, differed from the LR4 with no variable valve timing or an active fuel management system. The 5. The L33 was a high-output version for the truck line.
Although smaller in displacement than the 5. A key attraction was its ability to operate at reduced vibration and noise levels. The engine displaced cubic inches, or 4, cc, and had a compression ratio of 9. It had a 3.

We'll send you one email per day with the latest GM updates. I completely agree especially when you look at the competition like Ford with their new big gasoline V8 mated to the 10 speed. I will very likely buy the Chevy or HD with the 6. Except that Ram still uses the 6. Chevy offers more incentives in the HD series than ram or ford. The gas chevy will by far be more affordable and harder working, and most importantly longer lasting.
Businesses and most farmers the principle buyers of HD gas trucks will prefer the Chevy for practical purposes. Private buyers would likely go for the higher end Diesel, and that is a whole new can of worms. FCA threw parts at it for months before it mostly went away. Mikecollins, The problem with front ends is the grease. To prove my point, look for the darker spot on the interstates a couple of feet after a bump in the highway.
What is that dark spot? That is from both cars and trucks who are dropping grease onto the road after the vehicle hits a bump, from the flexing of the front end suspension parts. To solve that problem, do not use normal cheap grease.
Use only a synthetic front end grease. Firstly, it does not drop off onto the road like normal suspension grease. Secondly, it is not affected by water as much as normal grease. The main reason to use a synthetic grease is because it is much better at lubricating the parts, thus less wear. Just as normal petroleum oil does not protect the engine parts anywhere as well as a full synthetic, grease is the same.
I went and bought my own grease gun, put the tube of synthetic grease in it, wrapped it in two plastic bags and took it to my local oil change place and gave it to the guy to grease my front end parts.
We used to drive about to kilometers per day, so all parts wear faster.
Trust me, it make a huge difference to use the best lube stuff compared to normal petroleum lubes in your transmission, rear end, engine and suspension parts. It saves thousands of dollars on fuel use and engine life. DW is a BS artist. The NGLI 2 thick as butter grease has too high a viscosity to be thrown off with a little jounce in the suspension.The noise started a few months ago, on a rainy morning, but it went away before I even pulled out of the driveway.
Problem solved, right? The Squeal noise was back the very next morning, and this time it lasted all the way to the corner of my block. As the weeks dragged on, my morning commute got noisier and noisier every day.
Then I began to hear it on the way home too. Now it's a constant reminder to replace the belt.
