Engine Hyundai G4LC 1.4 l Information
The 1.4-liter Kappa engine, which debuted in the i20’s second generation in 2014, set a new standard for modern engines. It features an advanced fuel injection system with an aluminum block and cast iron liners, as well as a sixteen-valve head with hydro-compensators and chain-driven timing. Furthermore, it boasts Dual CVVT phasor controls on both the intake and exhaust camshafts – allowing for precise control of engine performance – while a plastic inlet manifold and Variable Intake System provide further efficiency. This high level of engineering make the 1.4-liter Kappa engine a leader in its field.
The manufacturer recognized the difficulties that arose from their past models and thus, implemented oil injectors for piston cooling in their next G4LC engine model. To further optimize reliability, the exhaust manifold was also improved so that crumbs of the catalyst would no longer be able to enter cylinders, creating a sturdy and dependable system that can ensure longevity.

Problems & disadvantages of the engine G4LC
Despite its lightweight design, the G4FA engine’s lackluster lubrication and low power levels have caused numerous difficulties. Issues such as vibratory loading, noisy injectors, decreased water pump life-span and inconsistent coolant/oil leakage are widespread among users of this power unit online. It can also be noted that simple leaf chains do not last long with active drivers due to stretching – another common complaint amongst forums discussing oil compounding solutions for this model motor.
The manufacturer says the engine life is 180,000 km, but it usually lasts up to 300,000 km.
