Disadvantages of the Hyundai G4KP engine
Since this turbo engine has only recently been introduced, it is too soon to discuss its dependability;
The existence of combined injection resolves the issue of coking inlet valves;
Timing chains are rapidly pulled by powerful turbocharged powertrains;
You must keep an eye on the cooling system of this extremely hot engine, and variable displacement oil pump units don’t increase reliability.
