Hyundai KIA 1.6L Engine (Gamma MPI/GDI/T-GDI) Problems, Reliability. The 1.6 L variation of the Gamma engine family has the following versions – G4FA, G4FC, G4FD, G4FG, and G4FJ. The very first Hyundai’s 1.6 L Gamma engine was the G4FC – a 1.6-liter four-cylinder gasoline engine with multi-point fuel injection presented in 2007 which ended up being a common engine alternative for Hyundai’s and KIA’s compact sedans and hatchbacks like Hyundai Accent, Elantra, KIA Rio, and Ceed.
The 1.6 MPI G4FC is based on a smaller 1.4-liter version in the Gamma family – the G4FA engine. This 1.6 L displacement was attained by installing a new crankshaft with increased stroke (from 75 mm up to 84.5 mm). The 1.6 l engine has longer linking rods and its own pistons (compression height varies from 1.4 l engine pistons). The G4FC is also entirely aluminum; it has an aluminum open-deck cylinder block and 16-valve double overhead camshaft (DOHC) aluminum cylinder head.
The 1.6 L G4FC is geared up with continually variable valve timing system called as CVVT for the intake timing just. The camshafts are chain driven. There are no hydraulic cam followers (valve clearance adjustment is required every 60k miles/100,000 km). The repaired geometry intake manifold is made of light-weight and inexpensive composite material. The engine utilized a multi-point fuel injection (MPI) managed by electronics. As you can see, the G4FC is a straightforward engine by modern-day requirements.

Hyundai KIA 1.6L Engine (Gamma MPI/GDI/T-GDI) Problems, Reliability
In 2010, the G4FC was replaced by the G4FG engine – the 1.6 L version of the updated Gamma II family. The G4FG engine is still geared up with a traditional MPI however likewise has visible divergences. The very first is the new engine got double CVVT system (variable valve timing for the consumption and the exhaust camshaft is used) and the second is the variable geometry intake manifold (Hyundai’s VIS system). New features raised the power and performance and brought a brand-new life for the most inexpensive 1.6 L Gamma engine.
The 1.6 GDI engine named as G4FD, was firstly introduced in 2008. It ended up being the very first Gamma engine which utilizes direct fuel injection. The engine got totally redeveloped cylinder head with direct fuel injectors in combustion chambers and the high-pressure fuel pump mounted on top. The high-pressure fuel pump is driven by an additional four-lobe camera on the exhaust camshaft.
The engine is geared up with an advanced Double CVVT system which assists to remove a high threat of detonation brought on by increased compression ratio to 11.0:1 for performance. The engineers also used the Variable Induction System (VIS) – the variable geometry intake manifold delivers a variable air flow based on speed conditions. The 1.6 GDI G4FD engine has higher fuel performance and power output together with low emissions.
A turbocharged version of the G4FD – the G4FJ or 1.6 L T-GDI, was introduced in 2011. The G4FJ engine includes a twin-scroll turbocharger, air-to-air intercooler, direct fuel injection system, double CVVT system, brand-new pistons, and 9.5:1 compression ratio.
Hyundai Gamma 1.6 L Engine Problems and Reliability
Hyundai’s 1.6 L engine is similar to the 1.4 l Gamma engine in terms of reliability and common problems. The all 1.6 l gamma engine feature noises, whistles, knocks and periodical problems with idle and vibrations. The oil begins leaking under the cylinder head valve cover at 30-40k mileage (a new gasket is needed). The consumption manifold rapidly becomes filthy inside triggered the unstable idling and power loss. Unique cleansing products and procedures are offered for cleansing channels and throttle valve. Oil leak from a turbocharger on the 1.6 T-GDI engine occurs uncommon, however if it does, it is at very low mileage.
In general, the engine does not provide severe problems with supplied correct maintenance and use of great fuel/lubricants. The engine life is slightly over 125-150k miles (200,000-250,000 km).
