Is the 1.0-1.6 8v Endura-E, Duratec 8v and RoCam reliable?

Simple, cheap 8-valve petrol engines from the Ka and Fiesta: the older 1.3 Endura-E with pushrods, its successor the 1.3 Duratec 8v and the 1.0 and 1.6 Zetec RoCam from Brazil. The sources speak of minor, recurring faults (tappet noise in the Endura-E; idle, coils, expansion tank and thermostat) rather than serious mechanical failures, although overheating can crack the head.^[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]
