1.2 8v vs 2.0 16v F4R and F4RT: which engine is more reliable?

According to our risk index, the 2.0 16v F4R and F4RT carries less risk than the 1.2 8v: 25/100 versus 36/100 (both moderate risk). The 1.2 8v has 1 documented serious fault, the main one being «Damaged cylinder head gasket (coolant loss and overheating)»; the 2.0 16v F4R and F4RT has 1 documented serious fault, the main one being «Timing belt failure due to overdue maintenance».

Is the 1.2 8v reliable?

The 1.2 8v (D7F) is a simple naturally aspirated engine of 54 to 60 hp, with a timing belt, which Renault fitted from 1996 to the Twingo, Clio II and Kangoo. No catastrophic failures are documented; what owner reviews mention most often are the sensors, the cylinder head gasket, the coil packs and the occasional oil drip.[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]
