 Consumer complaints about General Motors' Plastic Intake Manifold
I was told that the intake manifold gasket was leaking and that the engine was ingesting anti-freeze and, thus, causing the misfire in the cylinder number 2.
The service center at Tom Gill GM was aware that this is a problem with the gasket on this particular 3.4L motor.
I asked Dave (Pontiac Rep) if GM was going to reimburse me for the $735 needed to repair my van since it is obviously a design flaw and the dexcool antifreeze is under scrutiny by experts for causing this problem.

 PickupTruck.com - New 2001 GM Heavy Duty Trucks - Power, Towing, Suspension
GM spent twice as long testing the Duramax than any other previous engine at a total time of 2500 hours - roughly equal to 200,000 miles of wear and tear and at a severity level GM calls the 98th percentile.
While GM appears to be leading the class for now in the diesel engine wars, don't expect to see Ford and Dodge sit idly by.
This is the same engine used in the light duty trucks but tweaked to add more horsepower and torque (325hp@5000rpm and 370lb-ft@4000rpm).

 PickupTruck.Com - 2006 GM Duramax Heavy Duty Trucks
But GM is giving the current generation truck a majestic going-away party as the heavy-duty models now get the most powerful diesel engine available to pickup consumers.
With an additional overdrive gear, engine speed is reduced by 250 rpm at 60 mph to help with fuel economy and range.
The GM trucks were easy winners on flat roads and up the hill, but that’s not the main point that needs to be stressed.

The only two V6 engines ever available from the factory in a Jeep are the 225 "Dauntless" Buick V6 in the late 60s and early 70s and the 2.8L GM V6 in 80s Cherokees and Comanches.
GM 173(2.8L) V6 The 2.8L V6 engine uses a cast iron block and cylinder head with hydraulic lifters and over head valves.
The engine is manufactured by GM and uses a cast iron block and cylinder head with hydraulic lifters and 5 main bearings.

 Physics In an Automotive Engine
Engineering generally has a more "practical" approach, of working to get results that will be useful information toward actual mechanisms, without necessarily actually understanding WHY some particular formula is as it is. Physics is less concerned with applications or usage of results, and more concerned about understanding why some process proceeds as it does.
Engine durability is less than it used to be, but people rarely seem to keep vehicles as long as they used to, so it is apparently not considered a problem.
According to GM information, the frontal area of the car is around 19 square feet, the aerodynamic coefficient of drag (due to the shape of the car, and fairly constant for different speeds) is 0.330 and the tire resistance drag is around 0.015 (depending on tire type, inflation pressure, temperature and speed).

Based on the 5.9-liter Cummins turbo-diesel engine, the new 6.7-liter engine is 50% quieter, while featuring a 107mm bore by 124mm stroke (versus 102mm bore by 120mm stroke for the 5.9-liter engine).
The new 6.7-liter turbo-diesel engine incorporates several new features that contribute to a 50% quieter engine and a 3 dBa reduction in cabin sound levels, increasing the vehicle's overall refinement.
GM’s cleaner and more powerful Duramax 6.6-liter turbodiesel will be available on its new heavy-duty pickups, and they are said to pump out 365 hp and 660 lb-ft (895 Nm) of torque.

The Iron Duke (also called the 2500, 151, Pontiac 2.5, Cross Flow, and Tech IV, though the decal on the air filter assemblies actually reads "4 Tech") was a 2.5 L (151 in³) I4 piston engine.
This 151 was also used by American Motors (AMC) starting in 1979, as the base engine option in the RWD Spirit and Concord, as well as in the AWD (4x4) Eagle models through the 1983 model year.
The engine was updated one final time the next year with balance shafts, new pistons, rods, crankshaft, and an in-pan oiling system.

 Gas vs. Diesel Engines: The Big 3 | Advance Auto Parts   (Site not responding. Last check: 2007-09-26)
The base engine is the new 5.7L gasoline V-8 that's not only the most powerful base engine of this group at 345-hp, but revives the historical Hemi name and accompanying hemispherical cylinder head combustion chambers.
The base engine is a 5.4L gas V-8 that seems strong when installed in an F-150, but struggles when trying to move the mass of an F-250 or F-350, much less a trailer.
Even though this engine is one of our favorite GM truck powerplants of all-time, mating it to the optional Allison-built automatic transmission makes it even better.

 GM LS engine - Wikipedia, the free encyclopedia
Engines were cast from aluminum (for cars) instead of iron and had a new intake and injection technology and coil-on-plug ignition.
It is an all-aluminum 5.7 L (346 in³) pushrod engine and was rated between 288 - 345 hp (212 to 257 kW) and 325-350 ft·lbf (439-475 N·m) of torque in North America, depending on the application.
During GM's reliability testing of this engine in its prototype phase, the LS7 was remarked to have been repeatedly tested to be 8000 rpm capable, although power was not made at that rpm level, due to the restraints of the camshaft's profile and the intake manifold ability to flow required air at that engine speed.

Introduced to the Silverado line this spring, GM's new Quadrasteer 4-wheel-steering system is designed to provide a tighter turning radius by turning the rear wheels counter to the fronts at low speeds.
GM has already announced an optional hybrid gasoline/electric powertrain for Silverado starting in calendar 2004.
But where the Cadillac engine suffered poor drivability with the simple, low-power computing technology of the time, the DOD V-8 is said to have 50 times the processing power.

GM LS1 engine in a Chevrolet Corvette C5 The LS1 was an evolution of the earlier LT small-block V8 (and is almost identical to the LT4 except for its aluminum construction).
A version of this engine is adapted for transverse front wheel drive application, the first time a small-block family engine has been used in this manner since the Oldsmobile Aurora of the late 90s, it had a 4.0L V8.
Chevrolet also had an experimental big-block engine named LS7 in the late 60's that were supposed to be in the 1970 Corvette, but it never materialized.

An engine is a complex component that requires the highest degree of technical knowledge to install.
On engines that use a 1-piece full circle rear main seal and flangeless flywheel mounting system, over-torque of the flywheel bolts may distort the rear seal area and cause a leak.

Upgrades to the engine and a new diesel particulate filter system help ensure the engine meets government-mandated emissions regulations for diesel engines manufactured beginning in January 2007, which require a 90-percent reduction in particulate matter and 50-percent reduction in NO x.
Upgrades implemented in 2006 enhanced the efficiency, smoothness and quietness of the Duramax engine, which was already known as one of the industry's quietest and strongest diesels.
The engine also features a rigid cast iron cylinder block with induction-hardened cylinder bores; four-bolt, cross-drilled main bearing caps; forged steel, nitride-hardened crankshaft; aluminum pistons with jet-spray oil cooling; aluminum cylinder heads with four valves per cylinder; integrated oil cooler and a charge-cooled turbocharging system.

Some twin-turbo engines have the turbos arranged such that exhaust flow from one bank of cylinders drives a turbo which boost the intake of another bank.
This problem is especially serious to modern diesel engines, because they tend to use big turbo to compensate for their lack of efficiency.
That means the engine becomes lazy to rev (and to thrill you), but at any time you have a lot of torque to access, without needing to change gears frequently.
