Ecotec 1.4L Turbo Engine Reliability [How Good this 1.4L Chevy Engine Is !]

For a good reason, it is known as “the little engine that could.” In every manner, the turbocharged 1.3L 3-cylinder engine tested in the ’21 Chevrolet Trailblazer comes up to that description.

Reliability of Ecotec 1.4L turbo engine , which produces 155 horsepower and 174 pound-feet (236 Nm) of torque, makes its way into the 2021 top Ten Engines and Propulsion Systems list, thanks to a combination of technology and compact dimensions torquey reaction.

The 116 hp per liter output puts it over the top, outperforming its larger V-8 cousins in the Corvette Stingray with thirty-seven hp per liter.

That’s not to say the 6.2L OHV is comparatively tiny in the Corvette, a mid-engine design that reached the 2020 list and is still one of the best in terms of sheer performance.

But time passes, and the well-equipped $30,730 Trendsetter compact CUV offers a different kind of attentiveness in a much smaller package.

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.

Based on 15,000 miles annually driven, the Chevy Cruze should last 13–17 years before breaking or requiring costly repairs.

How Much Mileage Can a Chevy Cruze Give You?

Although the Cruze had a rocky start in existence, with engine and transmission issues plaguing 2011 and 2012 models, the Cruze’s subsequent model years would establish that it could endure the test of time.

Several Cruze owners had crossed the 200,000-mile mark, as many others had 150,000 miles on the milometer and were still going strong.

These automobiles are far from flawless, but they are built to last.

You may come across a few issues along the road, but with proper maintenance and an understanding that all cars require repairs, you can get it to 250k, as some have or are near to.

When checking at secondhand car websites like Car Gurus, you can find ones with over 200,000 miles and many more, including over 150,000 miles, demonstrating their longevity.

However, major component breaking is more dangerous once the automobile has collected many miles on the odometer. This includes the gearbox or engine. The expense of repairing the car will surpass its value.

Longevity of your Cruze, like any other car, is dependent on how well you care for it, and it will be shortened if you avoid:

  • Using high-quality components
  • Appointments for service
  • Oil changes regularly
  • Typical car washes
  • Rotation of tires
  • Smooth driving

Regular maintenance can extend the odometer by thousands of kilometers.

Are Chevy Cruzes Rusty?

The Chevrolet Cruze is not known for rusting readily, but after three or more years of use, some rusting is to be expected; this is dependent on several factors such as environment, storage, and how often you wash your car.

It will be impossible to eliminate rust if automobile bodies are composed of sheet steel as well as road surfaces contain small stones and grit.

While driving, these stones lacerate the paint, generating assault areas for water as well as road salt. Rust is a common occurrence. This includes

  • Underbody on the Chevy
  • frame rail beneath the trunk
  • Back drums
  • Doorway jams

Rust will be more of an issue if you live where roads are routinely salted throughout the winter or where salt air is widespread.

Some owners strongly advise rustproofing if you reside in the Salt Belt. Rust will be less of an issue for individuals who live in dry climates. Paint fading, on the other hand, will be more likely.
