Disadvantages of the Hyundai G4KF engine
The crankshaft liners’ rotation is this unit’s most well-known issue.
Additionally, pistons frequently burst or rods broke off in the early engine modifications.
Phase regulators and timing chains are used for a considerable amount of time—sometimes less than 100,000 kilometers.
Oil consumption appears and increases after 100,000 km because of the cylinders’ ellipse.
Most significantly, stock engines are hard to come by because nearly all of them are tuned.
