Is the 1.25/1.4/1.6 Ti-VCT reliable?

The Ti-VCT is Ford's family of naturally aspirated petrol engines (Sigma, Zetec-SE or Duratec), in 1.25, 1.4, 1.5 and 1.6 litres, fitted to the Fiesta, Focus, C-Max, B-Max, EcoSport and Ka+ between 2003 and 2022. It is a reliable engine in general: its best-documented fault, a variable valve timing actuator that could seize, is concentrated in the oldest units (Focus II and C-Max I) and was corrected afterwards.[1][2][3][4]

Is the 1.4 / 1.6 16v E-TEC II reliable?

The 1.4 and 1.6 16v GM Daewoo E-TEC II (first-generation Lacetti/Optra and Aveo) have a timing belt and, according to the Polish press, a moderate fault record. Documented issues are faulty valves in the first units (2004-2005), lambda sensor faults and a few cases of oil leaks or oil consumption.[5][6][7]
