GM 4.3L V6 EcoTec3 LV3 Engine: Specs, Problems, and Reliability. The 4.3 EcoTec3 is a 4.3-liter V-6 gasoline direct-injected and naturally-aspirated engine first appearance in the 2014 model year Chevrolet Silverado and GMC Sierra as the new base engine option. The LV3 4.3 L V6 motor was designed for primary use in pickup trucks and commercial vans. It's based on GM's 5th-generation small block 5.3 V8, replacing the 4.3 Vortec V6 out of the gen-4 small block V8 engine family. Like its forerunner, the LV3 V6 was built around V8's small block with a pair of cylinders removed. It also involves such modern components as cylinder deactivation, direct fuel injection, and continuously variable valve timing technologies. Let's take a closer consider the GM 4.3 EcoTec3 engine design, its common problems, reliability, and longevity.
The LV3 engine block is aluminum. Like the original V8 cylinder block, it has a 90-degree cylinder angle and 4.40-inch (111.8 mm) bore. Compared to the gen4 block, the EcoTec3 block casting is all-new with some changes in the design, providing new engine mount attachments, improved sealing, new knock sensor locations, and more. Like all Gen 5 engines, the new 4.3 V6 also provides oil-spray piston cooling. It has six piston oil jets/squirters, which spray additional oil underside of each piston, providing extra cooling and friction-reducing. The oil-spray squirters play an important role in long-term engine durability as well as noise reduction originating from the engine.
