About the G4KD Engine
The G4KD is Hyundai and Kia’s 2.0 litre Theta II port injected four cylinder, fitted to the Hyundai i45 and ix35 and to the Kia Sportage and Cerato between 2008 and 2014. Unlike its direct injection relatives it runs multi point injection with dual CVVT, and for most of its life it is an unremarkable, reliable engine.
Then it starts burning oil.
Here is what is actually happening. The catalytic converter substrate breaks down with age, and on deceleration and overrun the engine draws some of that loose ceramic material back up into the combustion chambers. Ceramic is harder than the cylinder wall. Every particle that gets in there scores the bore, the rings lose their seal, and the engine begins consuming oil — first a litre between services, then a litre a month, then blue smoke and a knock. Timing chain stretch before 150,000 kilometres and hardening gaskets fill out the picture.
Every G4KD we supply is brand new, built to current production standard with the bore, ring and chain weaknesses addressed. Hot tested before dispatch, shipped free anywhere in Australia with a one year warranty as standard, and no core exchange required.



Port Injection, Not Direct Injection
This is where most ordering mistakes happen, so it is worth being clear about. The G4KD is a port injected 2.0 litre engine. The 2.4 litre G4KJ and the 2.0 litre G4NC are both GDI direct injection. Different fuel systems, different cylinder heads, different calibration. They do not interchange, and the code stamped on your block is the only thing that settles it — not the badge on the boot, and not the year.
What Cars Have the G4KD Engine?
| Vehicle | Series | Years |
|---|---|---|
| Hyundai i45 | YF | 2010–2014 |
| Hyundai ix35 | LM | 2009–2013 |
| Kia Sportage | SL | 2010–2013 |
| Kia Cerato | TD | 2008–2013 |
Shopping for a specific car rather than by engine code? Each fitment has its own listing with the application already confirmed: Hyundai i45 G4KD engine, Hyundai ix35 G4KD engine, Kia Sportage G4KD engine and Kia Cerato G4KD engine. The ix35 and Sportage were both sold with more than one engine across these years, so if you are not certain which you have, send us the VIN or build plate and we will confirm it before anything is dispatched.
Common G4KD Engine Problems — and What We Have Done About Them
| Symptom | What is actually happening | Our engine |
|---|---|---|
| Burning oil, a litre between services or worse | Bore scoring from catalytic converter debris ingested on overrun | New block, new bore, new rings to factory tolerance |
| Blue smoke on start up or acceleration | Rings no longer sealing against a scored cylinder wall | Fresh bore and ring pack |
| Rattle on cold start that quietens | Timing chain stretch, common before 150,000 km on this engine | Current production chain, guides and tensioner |
| Oil weeping around covers and sump | Gasket hardening with age and heat | All new gaskets and seals |
| Knock developing after long term oil loss | Bearing damage from running the engine low on oil | New crankshaft and bearings |
G4KD Engine FAQs
What cars have the G4KD engine?
The G4KD 2.0 litre Theta II petrol engine was fitted to the Hyundai i45 (YF) and ix35 (LM), and to the Kia Sportage (SL) and Cerato (TD), across roughly 2008 to 2014.
Why does my G4KD burn oil?
Almost always bore scoring. The catalytic converter substrate breaks down and is drawn back into the cylinders on overrun, where the ceramic material scores the bore. The rings stop sealing and oil consumption climbs steadily. It is the defining failure of this engine.
Will a new engine fix the oil consumption permanently?
Only if the catalytic converter is dealt with at the same time. Fit a new engine behind a failed converter and the new bores will be scored the same way. Ask your mechanic to inspect or replace it as part of the job.
Can bore scoring in a G4KD be repaired?
The block can sometimes be bored oversize, but by the time most G4KD engines are diagnosed there is ring, piston and often bearing damage as well, and the cost converges on a new long motor with none of the warranty.
What is the difference between a G4KD and a G4KJ engine?
Displacement and fuel system. The G4KD is 2.0 litre with port injection; the G4KJ is 2.4 litre with GDI direct injection. Despite both being Theta II engines they are completely different units and do not interchange.
What is the difference between a G4KD and a G4NC engine?
Both are 2.0 litre, but the G4KD is a Theta II with port injection while the G4NC is from the Nu family with GDI direct injection. Different block, different head, different fuel system.
Is the G4KD engine brand new or reconditioned?
Brand new. Current production, hot tested before dispatch, with QR video proof supplied.
Does the G4KD engine include free postage?
Yes. Every G4KD engine ships with free postage Australia wide, fully insured and tracked.
