SUMMARY: The 1.4L Ecotec engine has shown to be a reliable engine that can last 100 000-200 000 miles (5-10 years) when properly maintained.
Architecture Ecotec 1.4L Turbo Engine
As the architecture is intended for numerous global applications, the Ecotec I-3 must balance challenging objectives: high transient response, low NVH, and good gas mileage CO2 emissions, based on vehicle size.
To provide quick boosting pressure, direct fuel injection, and intake and exhaust cam phasing, the all-aluminum DOHC engine is supplied by a single-scroll turbo linked to a head-integrated exhaust manifold.
The all-wheel-drive, 9-speed automatic test vehicle’s fuel economy is at 26/30 mpg (9.0-7.8 L/100 km) city/highway, thanks to an almost invisible 12V stop/start technology.
A variable oil pump performs a similar role in reducing friction. At the same time, active thermal management uses an electrical water pump and a control valve to help engine regions warm or cool quickly as needed.
Engineers use a profound cylinder block with an incorporated balance shaft, robust engine and gearbox mounts, a high-inertia crank dampener, acoustic coverings over the engine, fuel pump, and fuel rails to keep the engine quiet and refined.
It delivers adequate power from only three cylinders. This engine is a perfect match for this vehicle. Nobody needs to know the car only has three cylinders.
Most folks behind the wheel have no idea only three cylinders are working. The engine completes the transaction.
It is exciting to find a great machine in a high-volume, affordable, popular vehicle that comfortably seats at least four people and has plenty of cargo space.

Common 1.4L Ecotec Engine(+solutions)
Usual Ecotec 1.4l turbo engine reliability issues
Some owners of 1.4L Ecotec vehicles have reported problems with their timing chain, which the lack of lubrication can cause.
Make sure your automobile has enough oil and that your oil pump is new and clean to avoid this occurring to you.
A malfunctioning item dubbed a “PCV hose” can cause an oil spill and low oil flow in some 1.4L Ecotec models.
It is a simple fix; all you must do is replace your vehicle’s PCV pipe and periodically check your oil to ensure it does not become too low.
When drivers attempt to start their automobiles without first pressing the accelerator pedal, their vehicles may fail to ignite due to a clogged fuel injector.
General Motors 1.4L ECOTEC Fuel Combustion Issues SOLVED
When the 1.4liter Ecotec motors from General Motors began to consume more oil than usual, owners, as well as technicians alike, became concerned.
After presupposing the adversity- that the machines’ interiors were prematurely wearing down, suggesting catastrophic damage – technicians were pleased to learn that the cause of GM 1.4L Ecotec fuel burning was significantly more straightforward.
Identifying the problem
Once the Ecotec 1.4l turbo engine reaches a certain age and mileage, the little non-return valve installed into the inlet manifold as part of the Ventilation system becomes dislodged.
This valve, which is little more than a rubber flap with a lock tab on one side, falls out of its mounting with nothing to hold it in place.
When this valve is removed (usually by being sucked via the inlet manifold and burned up), evaporated oil is free to travel through the engine, increasing oil consumption.
This video shows you why the GM 1.4l chevy engine has oil burning problems.
Researching for a solution
Repairing the old inlet with a new factory part may solve the problem temporarily, but it almost guarantees the owner will have to do the same fix again in the future.
After examining the source of the problem, the innovation team devised a clever way to retain the valve in place even if its keeper failed.
The valve in this enhanced design is now captive, reducing the possibility of it becoming dislodged, thanks to the inclusion of a retention insert in the intake manifold.
Advantage intake manifold corrects a flaw in the OEM design. However, the team’s engineers realized that the problems were not solved by simply replacing the manifold.
The initial failure has an unintended consequence of damaging additional essential components.
When the valves in the OEM intake manifold fail, it creates too much vacuum, damaging the diaphragm in the valve cover’s PCV cap.
As a result of air being pulled into the motor through this aperture, the engine runs rough. Both the inlet manifolds and the valve cover should be replaced simultaneously.
Owners can reduce excessive oil usage induced by the original equipment design with the Advantages of intake manifolds and direct replacement valve covers.
