Is the 2.0 / 2.4 i-VTEC reliable?

Naturally aspirated Honda petrol engines (K20/K24 and R20) with a timing chain. The only serious documented fault is camshaft wear in the early K20s (2003-2004); the R20A and K24Z show no serious faults in the sources consulted, and only isolated cases of oil consumption appear. The sample of testimonies is small.^{[1][2][3][4][5][6]}

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.^[7][8][9]
