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 16v reliable?

The 1.2 16v (D4F) and its 8-valve predecessor, the D7F, are simple naturally aspirated engines, used for over two decades as the entry-level option in Renault and Dacia cars, with a reputation for reliability: the reliability pages consulted document no catastrophic failures and no oil consumption. The most-cited problems are ignition coils and sensors and, on higher-mileage cars, the head gasket.^{[7][8][9][10]}
