This 3800 weighs only 22 lb (10 kg) more than the all-aluminum High Feature V6 that currently dominates GM's six-cylinder applications, despite being an all cast-iron design. The new intake manifold greatly improved airflow. To meet emissions standards, an EGR tube was placed in the intake manifold to reduce combustion temperatures.
The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.2 and 2.5 litres.Confusingly, the Ecotec name was also applied to both the Buick V6 Engine when used in Holden Vehicles, as well as the final DOHC derivatives of the previous GM Family II engine; the architecture was substantially re-engineered for this new Ecotec ...

The Northstar engine is a family of high-performance 90° V engines produced by General Motors between 1993 and 2011. Regarded as GM's most technically complex engine, the original double overhead cam, four valve per cylinder, aluminum block/aluminum head V8 design was developed by Oldsmobile R&D, [citation needed] but is most associated with Cadillac's Northstar series.
Since there is no room in the V between the cylinder banks for an intake system, all the intakes are on one side of the engine, and all the exhausts are on the other side. It uses a firing order of 1-5-3-6-2-4 (which is the firing order used by most straight-six engines), rather than the common V6 firing order of 1-2-3-4-5-6 or 1-6-5-4-3-2.
GM entered the diesel field with its acquisition of the Cleveland-based Winton Engine Company in 1930. Winton's main client was the Electro Motive Company, a producer of internal combustion-electric rail motorcars. GM acquired Electro Motive at roughly the same time as Winton.
GM's number for this recall is N242471620. GM issued another recall. The recall comes about the same time GM recalled more than 461,000 cars for a rear wheel lock-up issue. Affected models include:
It featured the same multiport fuel injection intake manifolds and throttle body as the LH0, and produced 205 hp (153 kW) at 5200 rpm and 225 lb⋅ft (305 N⋅m) of torque at 2100 rpm. Around 3,700 engines were produced each year. This engine had a block with more nickel content and hardened internals. Applications:
