But time flies, and the well-equipped, trend-setting compact CUV for $30,730 offers adifferent faceCare in a much smaller package.

SUMMARY:The 1.4 liter Ecotec engine has proven to be a reliable engine that can last 100,000 to 200,000 miles (5 to 10 years) with proper maintenance.


Architecture Ecotec 1.4L Turbo Engine

As the architecture is designed for numerous global applications, the Ecotec I-3 needs to balance demanding targets: high transient response, low NVH and good CO2 emissions per fuel consumption, depending on vehicle size.

To provide fast boost pressure, direct fuel injection and gradual intake and exhaust cam timing, the all-aluminum DOHC engine is powered by a single-scroll turbo connected to an exhaust manifold integrated into the cylinder head.

Thanks to the nearly invisible 12-volt start/stop technology, the four-wheel drive nine-speed automatic tester's fuel economy is 26/30 mpg (9.0-7.8 l/100 km) city/highway.

A variable oil pump plays a similar role in reducing friction. At the same time, Active Thermal Management uses an electric water pump and control valve to quickly heat or cool areas of the engine as needed.

Engineers used a deep cylinder block with an integrated balancer shaft, robust engine and transmission mounts, a high-inertia crankshaft damper, acoustic engine covers, fuel pump and fuel rails to keep the engine quiet and refined. .

It offers enough power with just three cylinders. This engine is a perfect match for this vehicle. Nobody needs to know that the car only has three cylinders.

Most people behind the wheel have no idea that only three cylinders are working. The engine completes the transaction.

It's exciting to find a great machine in a popular, affordable, large-capacity vehicle that seats at least four people and loads of cargo space.

Common Reliability Issues with the Ecotec 1.4 Liter Turbo Engine

some owners ofEcotec 1.4L VehiclesYou have reported problems with your timing chain that could lead to insufficient lubrication.

Make sure your car has enough oil and your oil pump is new and clean to prevent this from happening to you.

A faulty item called the "PCV hose" can cause oil leakage and low oil flow on some Ecotec 1.4 liter models.

It's a simple solution; All you need to do is replace your vehicle's PCV pipe and regularly check the oil level to make sure it's not too low.

When drivers attempt to start their cars without first pressing the gas pedal, their vehicles may not start due to a clogged fuel injector.

General Motors 1.4L ECOTEC fuel combustion issues FIXED

if that1.4 liter Ecotec enginesfrom General Motors started to use more oil than usual, owners and technicians began to worry.

After assuming that the machines' interiors were prematurely wearing out, indicating catastrophic damage, technicians were pleased to discover that the cause of the GM 1.4L Ecotec's fuel consumption was much simpler.

identify the problem

once themotor ecotec 1.4l turboAfter a certain age and mileage, the small check valve built into the intake manifold as part of the ventilation system becomes displaced.

Little more than a rubber tab with a locking tab on one side, this valve pops out of its holder without being held in place.

If this valve is removed (usually by sucking it through the intake manifold and burning it), the evaporated oil is free to flow through the engine, increasing oil consumption.

This video shows why the Chevy GM 1.4 liter engine has oil combustion problems.

look for a solution

Fixing the old intake with a new factory part may temporarily fix the problem, but it almost guarantees that the homeowner will have to do the same repair again in the future.

After investigating the source of the problem, the innovation team found a clever way to keep the valve in place even if the bracket fails.

The valve in this improved design is now captive, reducing the chance of bursting thanks to the incorporation of a check insert in the intake manifold.

The Advantage intake manifold fixes an OEM design flaw. However, the team's engineers found that the problems could not be resolved by simply replacing the distributor.

An initial failure has an unintended consequence of damaging additional critical components.

If the valves in the OEM intake manifold fail, excessive vacuum will be created and the diaphragm in the valve cover PCV cap will be damaged.

The engine runs erratically as a result of air entering the engine through this opening. Both the intake manifold and valve cover must be replaced at the same time.

Owners can reduce excessive oil consumption caused by OE design with the benefits of direct-change intake manifolds and valve covers.
