Remanufactured 1.4 Turbo Ecotec Motor

This remanufactured 2014 Chevrolet Cruze 1.4T engine is the ECOTEC TURBO 1.4L variable valve timing DOHC 4-cylinder with sequential multiport fuel injection. It carries factory codes LUJ and LUV, VIN identifier B in the 8th digit, and produces 138HP from an iron block with casting number 55577377. Built to meet and exceed OEM spec, it ships as a long block with seals, gaskets, harmonic balancer, and dual VVT timing already installed.

If your Cruze has been fighting timing chain stretch, turbo related power loss, or the excessive oil consumption so often reported on this 1.4L, a reman engine solves the root cause instead of patching symptoms. Every internal wear component is replaced or reconditioned, so bearings, rings, and seals start fresh at zero miles. The block is bored and honed to OEM clearances, giving you durability that equals or exceeds the original Ecotec motor you are removing.

Engine Specs And Exact Fitment

The core engine is a 1.4 liter, 85 cubic inch inline four with DOHC 16-valve architecture and cast iron block. It delivers 138 horsepower at 4,900 RPM and 148 lb ft of torque low in the band at 1,850 RPM. Features include a 58X ignition system, coil on plug firing, returnless fuel rail, piston cooling oil jets, integrated oil cooler, variable flow oil pump, and an electronically controlled thermostat.

Fitment covers the 2011, 2012, 2013, 2014, and 2015 Chevrolet Cruze in LT, LTZ, and Eco trims running the turbocharged 1.4L. Applicable RPO codes are LUJ, LUV, and LE2. This front wheel drive setup pairs with the 6-speed automatic with overdrive or the 6-speed manual, both common in the 2014 Cruze, so your existing transmission bolts right back up.

Before ordering, confirm your VIN shows a B in the 8th digit and verify your current engine casting matches 55577377 on the block and 55573669 on the head. This same LUJ/V engine family appeared in the Sonic, Trax, Volt, GMC Terrain, and Buick Encore, so matching displacement, codes, and casting is the surest way to guarantee a correct, bolt in replacement.

What Is And Is Not Included

This unit is supplied as a long block with seals and gaskets. It includes the engine block, crankshaft, pistons, connecting rods, bearings, camshafts, assembled cylinder head, and valvetrain. The harmonic balancer is included, the 6-groove front pulley is installed, dual VVT timing is set, and the timing cover is included with this program.

Not included are the flexplate, flywheel, intake manifold, and oil pan. External accessories such as the turbocharger, fuel injectors, pumps, wiring harness, sensors, and emissions equipment are not part of a long block. Plan to transfer your known good components, or replace any that show wear, when the engine goes in.

Because exact long block contents vary by remanufacturing program, we encourage every buyer to confirm the parts list with us before placing an order. That quick check prevents surprises on install day and ensures you have the right gaskets, bolt on parts, and emissions hardware ready for your specific 2014 Cruze build.

Remanufacturing means returning a worn engine as close to new as possible, not simply cleaning and reselling it. Every core is completely disassembled, cleaned, inspected, remachined, reassembled, and tested. We bore and hone all cylinders to OEM clearances and verify every tolerance within one ten thousandth of an inch. New timing components are installed where the design requires them, a new oil pump goes in, and all critical gaskets and seals are replaced so the assembled engine behaves like a factory unit.

Before any engine leaves the floor, it undergoes cold motored Sims testing to verify compression, oil pressure, torque to turn, and overall mechanical integrity, and it is dyno tested to confirm performance. This process directly targets the documented failure points of the 1.4T Cruze, replacing the rings and valve seals tied to oil consumption, renewing bearings, and resurfacing the head and block decks. The result is a rebuilt to spec engine that addresses the exact weaknesses owners report.

Reman Versus A Used Engine

A used engine carries unknown mileage and unknown prior wear, meaning any timing chain stretch, turbo damage, or ring wear comes along with it. A remanufactured 1.4T starts at zero miles with rebuilt internals, so you are not inheriting the same high mileage problems you are trying to escape.

The quality of a remanufactured engine is typically as good as, and often better than, the original new product. With today's improved bodies and chassis, putting a reman engine in a sound Cruze makes clear economic sense because you restore performance and durability without buying another whole vehicle.

Choosing reman is also the greener path. Remanufacturing reuses the original casting and reduces energy, water, and material waste compared with producing a new engine. You get a durable, tested motor built to OEM specification while keeping a solid iron block in service instead of scrapping it.

Every reman engine purchase includes a refundable core charge, which is a temporary deposit added to ensure your old engine is returned for remanufacturing. Your core is the used engine you remove, and it must be the same make, model, displacement, and casting as the unit you buy. For this Cruze engine that means a matching 1.4L LUJ/V long block with casting numbers that correspond to the replacement.

To qualify for a full core refund, the returned engine must be long block complete, including block, heads, crank, cam, rods, pistons, and timing components. It cannot have holes or cracks in the block or heads, and major components cannot be broken or missing. Internals must stay intact, though bolt on accessories may be removed. Return your core promptly in the original crate and the refundable portion is credited back once it is inspected.

Installation Checks And Buyer Guidance

Because the 1.4T is sold as a long block, plan to transfer and inspect the bolt on parts before firing it up. Check turbocharger shaft play and replace the turbo if it shows wear, since turbo failure is a common Cruze complaint that shows up as power loss and higher fuel use. Reuse only components that pass inspection, and renew anything questionable while the engine is out of the bay.

Confirm PCV and intake manifold integrity during the swap, as PCV faults contribute to the oil consumption and pressure problems reported on these engines. Install a fresh oil pan gasket and address any coolant leak points, since coolant and oil leaks are among the most frequent 2014 Cruze engine issues. A leak down test after assembly confirms the head gasket and pistons are road ready before the car returns to service.

Use new fluids, a quality oil filter, and follow a careful break in on first start, watching oil pressure immediately. Torque the flexplate or flywheel and intake manifold to GM specification, and verify the 58X crank sensor and coil on plug connections are clean. Matching your VIN code B and casting numbers up front, then documenting every step, protects both the engine and your warranty coverage.

Frequently Asked Questions

What is the engine code for the 2014 Chevy Cruze 1.4T?

The factory codes are LUJ and LUV, sometimes written together as LUJ/V, with LE2 also applying on later applications. The VIN identifier is the letter B in the 8th digit of the vehicle identification number, and the block casting number is 55577377.

What is included in this remanufactured Cruze 1.4T long block?

It ships as a long block with seals and gaskets, including the harmonic balancer, the installed 6-groove front pulley, dual VVT timing, and the timing cover. Not included are the oil pan, intake manifold, and flywheel or flexplate, so plan to transfer those parts.

What are the most common problems with the 2014 Cruze 1.4T engine?

Owners frequently report coolant leaks, oil leaks, turbocharger failures, and timing chain stretch or failure. Excessive oil consumption, often traced to piston rings or valve seals, is also widely reported. A reman engine with new rings, seals, and bearings directly addresses these documented failure points.

Is a remanufactured engine better than a used engine for a 2014 Cruze?

Yes for most buyers. A reman engine starts at zero miles with rebuilt internals and is tested to OEM spec, so its performance and durability should equal or exceed the original. A used engine carries unknown mileage and unknown prior wear, including the problems you are trying to replace.

Will this engine fit other Chevy Cruze model years?

This same 1.4L LUJ/V turbo engine fits the 2011, 2012, 2013, 2014, and 2015 Cruze in LT, LTZ, and Eco trims. Always confirm your VIN shows a B in the 8th digit and that your casting numbers match before ordering to guarantee a correct fit.

What is a core charge and how do I get it refunded?

A core charge is a refundable deposit added to ensure your old engine comes back for remanufacturing. To earn the full refund, return a long block complete 1.4L core of matching make, model, displacement, and casting, with no cracks or missing major components and internals intact.

Is this engine tested before it ships?

Every unit undergoes cold motored Sims testing to verify compression, oil pressure, torque to turn, and mechanical integrity, and it is dyno tested for performance. Cylinders are bored and honed to OEM clearances with tolerances checked within one ten thousandth of an inch, so the engine is verified before it leaves us.

Does this engine include the turbocharger and fuel injectors?

No. As a long block, it does not include the turbocharger, fuel injectors, pumps, intake manifold, harness, sensors, or emissions equipment. Transfer your known good external components or replace any that show wear, and inspect turbo shaft play before installation since turbo failure is common on this engine.

What horsepower and torque does the 1.4T Ecotec produce?

This 1.4 liter DOHC 16-valve turbo four produces 138 horsepower at 4,900 RPM and 148 lb ft of torque low in the range at 1,850 RPM. It is a front wheel drive engine that pairs with the 6-speed automatic or 6-speed manual used in the 2014 Cruze.

What should I check before and during installation?

Verify VIN code B and your casting numbers, inspect turbo shaft play, confirm PCV and intake manifold integrity, and perform a leak down test to confirm head gasket and pistons are ready. Transfer the oil pan, intake manifold, and flexplate or flywheel, and use fresh fluids with a careful break in.
