2.0 / 2.4 i-VTEC vs 1.4 and 1.6 16v: which engine is more reliable?

According to our risk index, the 2.0 / 2.4 i-VTEC carries less risk than the 1.4 and 1.6 16v: 23/100 (low risk) versus 45/100 (moderate risk). The 2.0 / 2.4 i-VTEC has 1 documented serious fault, the main one being «Camshaft wear and pitting on the 2.0 K20 (Accord VII, CR-V II, Civic)»; the 1.4 and 1.6 16v has 1 documented serious fault, the main one being «Timing belt breakage or premature failure».

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 1.4 and 1.6 16v reliable?

The K4J (1.4) and K4M (1.6), both naturally aspirated 16-valve units, are simple and generally reliable petrol engines: no source consulted documents oil consumption or faults that destroy the block. Their most-cited weak point is the ignition coils, followed by the crankshaft sensor and, on versions with a variable valve timing unit, its pulley; a neglected belt can cause serious damage, as one case in the Renault Laguna II documents.^{[7][8][9][10]}
