Is the 2.2 Ecotec gasolina reliable?

This is the 2.2 petrol engine producing 147 to 155 hp in the Astra G, Zafira, Vectra and Signum. Its documented weak point is the timing chain, which stretches and can end in serious engine damage; the 2.2 Direct adds a high-pressure pump prone to failure.^[1][2][3]

Is the 2.0 16v F4R and F4RT reliable?

In the sources we consulted, the 2.0-litre F4R and F4RT show no engine-destroying design faults, but the timing belt must be changed on time, and the coils (RS) and the variable valve timing pulley appear as weak points. We have found no reliable sources on oil consumption or big-end bearings.^[4][5][6][7]
