G4LC Engine for Sale — Brand New 1.4L Petrol Crate Engine
The G4LC engine is Hyundai and Kia’s 1.4 litre Kappa four cylinder petrol, and it powers a very large number of small cars on Australian roads — the Hyundai Accent, the Kia Rio and the Kia Stonic, along with the i20 and Ceed in export markets. It is a light, efficient, port injected engine, and for the first hundred and something thousand kilometres it gives almost no trouble.
Then it starts using oil.
Here is what is actually happening. The G4LC was built significantly lighter than the G4FA it replaced, and much of that weight came out of the connecting rod and piston assembly. Around the 150,000 kilometre mark that reduced material begins to show as ring and piston wear. The rings lose their seal, oil consumption climbs, and because these are small capacity engines that get worked hard in traffic it can escalate quickly once it starts. Left alone, the engine runs low on oil between checks and the bearings follow.
Timing chain stretch under hard driving, noisy injectors and water pump failures round out the list.
Every G4LC we supply is brand new, built to current production standard with the piston, ring and chain weaknesses addressed. Hot tested before dispatch with QR video proof, shipped free anywhere in Australia, one year warranty as standard, and no core exchange required — your old engine stays with you.



Is It Worth Replacing the Engine in a Small Car?
Fair question, and one worth answering honestly rather than dodging.
A new G4LC is a meaningful share of what a used Rio or Accent is worth. But the comparison that actually matters is not engine cost versus car value — it is engine cost versus what else you would get for the money.
A brand new long motor in a car you already know — one you have serviced, whose history you trust, whose tyres and brakes and registration you have already paid for — resets the single most expensive component and buys you years. For a lot of owners that is the best value decision available, not the worst.
What Cars Have the G4LC Engine?
| Vehicle | Series | Years |
|---|---|---|
| Hyundai Accent | RB | 2016–2024 |
| Kia Rio | YB | 2015–2019 |
| Kia Stonic | — | 2018–2024 |
Also fitted to the Hyundai i20 and i30 1.4, the Kia Ceed and the Rio X-Line in export markets across a similar period.
Shopping for a specific car rather than by engine code? See our Kia Rio engine and Kia Stonic engine pages. The Rio and Accent were both sold with more than one engine across these years, so if you are not certain which you have, send us your VIN or build plate and we will confirm it before anything is dispatched.
Common G4LC Engine Problems — and What We Have Done About Them
| Symptom | What is actually happening | Our engine |
|---|---|---|
| Oil light between services, topping up regularly | Piston and ring wear from the lightened rotating assembly, typically around 150,000 km | New pistons, rings and bore to factory tolerance |
| Blue smoke on start up or under acceleration | Rings no longer sealing | Fresh bore and ring pack |
| Rattle on cold start that quietens | Timing chain stretch, accelerated by hard driving | Current production chain, guides and tensioner |
| Ticking or buzzing from the top of the engine | Noisy injector operation, common on this engine | New head and valvetrain |
| Coolant loss or overheating | Water pump failure, a known weak point | Inspect and replace the pump when fitting |
| Knock after long term oil loss | Bearing damage from running the engine low on oil | New crankshaft and bearings |

G4LC Engine FAQs
What cars have the G4LC engine?
The G4LC 1.4 litre Kappa petrol engine was fitted to the Hyundai Accent (RB), Kia Rio (YB) and Kia Stonic across roughly 2015 to 2024, and to the Hyundai i20, i30 1.4 and Kia Ceed in export markets.
Why does my G4LC burn oil?
Piston and ring wear. The G4LC was built lighter than the engine it replaced, with material taken out of the connecting rod and piston assembly, and that shows as ring wear from around 150,000 kilometres. Once the rings stop sealing, oil consumption climbs steadily.
Is it worth replacing the engine in a Kia Rio or Hyundai Accent?
Often, yes. The comparison is not engine cost versus car value, it is engine cost versus a $12,000-plus replacement car with a history you know nothing about. A new long motor in a car you already know and have maintained resets the most expensive component and buys years.
What is the difference between a G4LC and a G4LA engine?
Displacement. The G4LC is 1.4 litre and the G4LA is 1.2 litre, the engine used in the Kia Picanto. Same Kappa family, different engines, and they do not interchange.
Should I replace anything else while the engine is out?
Yes, the water pump and thermostat. Both are known failure items on the G4LC, and doing them while the engine is already out costs a fraction of doing them later.
Is the G4LC engine brand new or reconditioned?
Brand new. Current production, hot tested before dispatch, with QR video proof supplied.
Does the G4LC engine include free postage?
Yes. Every G4LC engine ships with free postage Australia wide, fully insured and tracked.
