Additional notes

Hyundai/Kia Gamma 1.6 GDI (i30/Ceed/Elantra) suffers significant carbon buildup on intake valves due to direct injection. Walnut blasting recommended every 60k km (€300-600). Failure to clean causes rough idle and power loss.
CHECK VIN: Hyundai/Kia 1.6 T-GDI (Theta II) had a recall for connecting rod bearing failure that can cause engine seizure. ALWAYS check if the recall was performed before buying. If recall done, risk is significantly lower.
