10 Of The Worst Engines Major Companies Ever Put In A Production Vehicle
By JUSTIN OWEN
Triumph V8
Although Triumph had access to the legendary Rover V8, they built a V8 from scratch. However, their design choices caused many of the engine’s problems.
One of the major issues was the water pump placement in the engine, which caused it to be starved of cooling water too easily, resulting in overheating and engine failure.
Cadillac V8-6-4
The Cadillac V8 is legendary in the American auto industry, but the 1980s fuel crisis resulted in a change to its design that led to the V8-6-4 engine.
This new engine used an engine management system that would change its power based on its setting. Unfortunately, the computer caused the engine to fail to work correctly.
Oldsmobile Diesel
Wanting to copy the success of European brands selling diesel in the United States, Oldsmobile used its proven gasoline 350 V8 as a basis for the diesel.
However, due to its design, the resulting engine fell short and suffered from critical engine failures. The power output was only 120 horsepower with 220 lb-ft of torque.
High Feature Engine
The GM 2.8 and 3.6-liter High Feature Engines sometimes developed a serious issue in year model cars from 2007 to 2010.
The primary concern for car owners was the stretching timing chain, which could result in misfires or catastrophic engine failures if the chain wasn’t regularly monitored.
Jaguar V12
While the Jaguar V12 engine is a fine piece of machinery, its overly complicated design can be a nightmare to navigate and costly to fix.
Among its several issues, perhaps the biggest headache is the electrical system, which is notorious for being temperamental and unreliable.
