Kappa 1.4 MPI (G4LC)
"The simple 1.4 petrol in the i20 GB, i30 GD/PD, Rio YB, Stonic and Ceed: port injection, no turbo, chain-driven, 100 hp. Expected to reach high mileage with regular oil changes. The thin timing chain can stretch, mostly after 80,000 km or on hard-driven cars, and oil use can rise past 150,000 km. Listen for a rattle on cold start and check the oil level."
G6DP 3.3 V6 TT
"Hyundai/Kia's 3.3 twin-turbo V6 (Lambda II, from 2016) with direct injection and a timing chain: 366 PS in the European Kia Stinger GT, also used in Genesis models. Strong and smooth. The one documented fault is the left turbocharger oil feed pipe, which can perish and leak oil onto hot parts; a worldwide recall (Europe 241039, US 24V-169) replaces it free of charge. Check the recall is done. Long-term data beyond that are still thin."
