Is the M60 and M62 reliable?

BMW's M60 and M62 V8s have a reputation for durability if the cooling system is looked after, but the M62 carries two well-documented weak points: the plastic chain guides of the timing chain and, from 1998, the VANOS seals. The M60 suffered cylinder wear from Nikasil with sulphur-contaminated petrol.[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]
