The Mitsubishi 4G3 series engine is a venerable and widely used powerplant, known for its reliability, durability, and relative simplicity. It was a popular choice for a variety of Mitsubishi vehicles, spanning decades of production. The 4G3 series encompasses a family of four-cylinder, naturally aspirated gasoline engines, with displacement ranging from 1.2 to 1.6 liters. They are known for their simple, SOHC design employing a timing belt instead of a chain, contributing to their affordability and ease of maintenance. The 4G3 engine family found its way into a wide range of Mitsubishi models, including the Lancer, Colt, Galant, and Mirage, both in sedan and hatchback configurations. This engine series proved to be quite versatile, finding applications in both front-wheel drive and rear-wheel drive vehicles. The Mitsubishi 4G3 series engine is renowned for its robust construction and impressive longevity. These engines are known to handle high mileage and, with proper care, can last for many years. Their straightforward design makes them relatively easy to work on, appealing to both professional mechanics and DIY enthusiasts. Parts are generally affordable and readily available. However, the engines are not without their drawbacks. While simple in design, the 4G3 series engines can exhibit some inherent weaknesses, including a propensity for valve guide wear, head gasket issues, and potential oil leaks. These engines typically utilize carburetors or early electronic fuel injection systems, which can require additional tuning and maintenance compared to modern fuel-injected systems. Despite these drawbacks, the Mitsubishi 4G3 series continues to be appreciated for its affordability, ease of maintenance, and proven reliability, especially in the hands of dedicated owners who are willing to invest in regular servicing and care.
