G4NA Engine For Sale

G4NA Engine for Sale — Brand New 2.0L Petrol Crate Engine

The G4NA engine is Hyundai and Kia’s 2.0 litre port injected Nu four cylinder, fitted to the Elantra, Tucson, Kia Cerato, Soul and Sportage from around 2014. It is the simpler of the two 2.0 litre Nu engines — no direct injection hardware, no high pressure pump — and on paper it should be the more durable of the pair.

In practice it has one specific failure that has taken out a very large number of these engines. And it starts somewhere most people would not think to look. Every G4NA engine for sale on this page is brand new, built to current production standard with that fault designed out.

If your car is not knocking yet — check your oilIf you own one of these cars and it is out of warranty, check the oil level every couple of weeks, not every service. The entire failure chain depends on the engine running low without anyone noticing. An owner who tops it up stays ahead of it. An owner who trusts the service interval finds out when it knocks.

✓ Brand new — never reconditioned

✓ Correctly specified rings and rotating assembly

✓ No core exchange required

✓ Free insured shipping Australia-wide

✓ One year warranty as standard

Why G4NA Engines Fail

STEP ONE

It starts with the piston rings

On a significant run of these engines the piston rings were not heat treated correctly, and they wear early. Worn rings stop sealing, and the engine begins consuming oil.

Here is the part that catches people out: it does not leak, it does not smoke much at first, and nothing on the dashboard tells you. The level just quietly drops.

STEP TWO

Then the bearings starve

Once the oil runs low, the connecting rod bearings are the first thing to go without lubrication. They seize onto the crankshaft journals and score them. What began as a ring problem ends as a rhythmic metallic hammering that rises and falls with engine speed.

That is rod knock. By the time you can hear it, the crankshaft is damaged and the engine is finished.

The problem was significant enough overseas to trigger recall programs, along with a software system that listens for the early stages of ring wear and puts the car into limp mode before the bearings let go.

If you are reading this because your car is knocking, that is the sequence you have been through. A brand new long motor is the repair. Every G4NA engine for sale here is built to current production standard with correctly specified rings and rotating assembly, so you are not buying back the same fault.

If Your Car Is Not Knocking Yet — Check Your Oil

This is the most useful thing on this page, and it costs nothing.

If you own one of these cars and it is out of warranty, check the oil level every couple of weeks, not every service. The entire failure chain depends on the engine running low without anyone noticing. An owner who tops it up stays ahead of it. An owner who trusts the service interval finds out when it knocks.

Symptoms worth acting on, in order of how much time you have left

1Using oil between services — roughly a litre every 800 to 1,600 km is the common pattern
2Faint blue or grey smoke, worst on start up or under load
3A light tick from the top of the engine
4Rhythmic metallic knocking that speeds up with the revs — stop driving it

The first three are warnings. The last one is the engine telling you it is already done. At that point a G4NA engine for sale as a complete new long motor is the only repair worth paying for.

G4NA or G4NC? Check Before You Order

Both are 2.0 litre Nu engines, and both went into the Tucson, Sportage and Cerato in overlapping years. They are not interchangeable.

G4NA — port injection

Injectors in the intake manifold. This engine, this page.

G4NC — GDI direct injection

Injectors in the cylinder head, fed by a high pressure pump driven off the camshaft. If that is what you have, you need our G4NC engine.

How to tell. The code is stamped on the block. If you cannot get to it, look for a high pressure fuel pump bolted to the cylinder head — that indicates the GDI. Still not sure? Send us your VIN and we will confirm it before anything is dispatched.

Common G4NA Engine Problems — and What We Have Done About Them

Symptom	What is actually happening	Our engine
Using a litre of oil between services	Piston ring wear, the root cause of nearly every G4NA failure	Correctly specified rings, new bore to factory tolerance
Blue or grey smoke, worst on start up	Rings no longer sealing	Fresh bore and ring pack
Light ticking from the top of the engine	Early valvetrain noise as oil pressure drops	New head and valvetrain
Rhythmic metallic knock rising with revs	Rod bearings have seized and scored the crankshaft journals	New crankshaft, rods and bearings to factory clearance
Oil pressure light, metal in the drained oil	Bearing material breaking up through the oil system	New rotating assembly, oil pressure verified on the hot test
Rattle on cold start that quietens	Timing chain wear	Current production chain, guides and tensioner

Why Buy Your G4NA From Crate Engines Australia

Every G4NA engine for sale through Crate Engines Australia is brand new, hot tested and shipped from stock in Queensland.

✓ Ring and rotating assembly weaknesses addressed in current production.
✓ Centra Steel crankshaft for increased durability compared to the standard variant.
✓ 2S maximum tolerance on machined surfaces, with a 1:1 OEM aligned specification.
✓ Minimum five years’ experience on every assembly technician.
✓ Hot tested before dispatch, with QR video proof supplied for your specific engine.
✓ No core exchange required — your old engine stays with you.
✓ Physically in stock at our Molendinar, Queensland warehouse. Not ordered offshore after you pay.
✓ Australian owned since 2017, 4.8 stars across 327+ verified buyers, warranty assessed here by real mechanics.

Used G4NA engines are the worst possible value in this category. The failure is progressive ring wear, not a single event. A used engine from a wrecker has the same rings, made the same way, from the same production run, and it is already partway through the same process. It will not show on a compression test and it will not sound wrong on start up. You find out in six months when it starts using oil, and you do the whole job again.

Warranty and Shipping

Every G4NA engine for sale includes a one year manufacture warranty as standard, extendable to two years at checkout. Coverage applies to the long block — crankshaft, pistons, rods, block and head integrity — and requires installation by a licensed mechanic with a verifiable tax invoice.

Heat tabs are fitted. Every engine carries a calibrated heat tab; overheating beyond the set limit voids coverage. Returns are accepted within 7 days provided the engine has not been used or dismantled.

Free shipping anywhere within Australia, fully insured and tracked, dispatched via Team Global Express from our Queensland warehouse. Stock engines ship same or next business day, with typical delivery in 6 to 8 business days and up to 11 days for remote areas. Express shipping is available at checkout.

G4NA Engine FAQs

What cars have the G4NA engine?

The G4NA 2.0 litre port injected petrol engine was fitted to the Hyundai Elantra (AD) and Tucson, and to the Kia Cerato, Soul (PS) and Sportage (QL), across roughly 2014 to 2021.

Why does my G4NA burn oil?

Piston ring wear. On a significant run of these engines the rings were not heat treated correctly and wear early, so they stop sealing. The engine consumes oil without leaking or smoking heavily, which is what makes it dangerous, because the level drops without anyone noticing.

What causes the knocking noise in a G4NA?

The oil consumption left unchecked. Once the level runs low the connecting rod bearings starve, seize onto the crankshaft journals and score them. That produces a rhythmic metallic knock that rises with engine speed. By the time you hear it, the crankshaft is damaged.

Can a knocking G4NA be repaired?

Not reliably. The crankshaft journals are scored and the bearing material is gone, and replacing bearing shells on a damaged crank buys months rather than years. A new long motor is the repair that holds.

How do I stop this happening to my next engine?

Check the oil level every couple of weeks rather than relying on the service interval. The whole failure chain depends on the engine running low without anyone noticing. Our engines are built with correctly specified rings, so consumption should not be the issue it was, but on any engine checking the oil is the cheapest insurance there is.

What is the difference between a G4NA and a G4NC engine?

Both are 2.0 litre Nu engines, but the G4NA is port injected and the G4NC is GDI direct injection. Different cylinder heads, different fuel systems, different calibration, and they do not interchange. If there is a high pressure fuel pump bolted to your cylinder head, you have a G4NC.

Is the G4NA engine brand new or reconditioned?

Brand new. Current production, hot tested before dispatch, with QR video proof supplied.

Does the G4NA engine include free postage?

Yes. Every G4NA engine ships with free postage Australia wide, fully insured and tracked.
