Is the 0.8 / 1.0 / 1.2 S-TEC reliable?

The GM Daewoo S-TEC engines (0.8, 1.0 and 1.2 naturally aspirated, low power) power the Matiz, Spark, Aveo 1.2, Beat and Sail. The sources consulted document only minor and cheap faults, such as oil leaks and ignition faults on the Matiz, and we have found no structural engine fault.[1][2][3]

Is the 1.6 and 2.0 8v EA827 reliable?

Simple, naturally aspirated petrol engines that, according to the sources, last a long time with regular maintenance. Gebrauchtwagenberater describes the 8-valve 1.6 as old-fashioned but reliable, and the 102 hp 1.6 MPI as even more reliable than the 1.4 16v. Watch the timing belt with the water pump, coolant leaks, oil consumption (especially on the 2.0) and idle and sensor faults.[4][5][6][7]
