1.6 and 1.8 Ecotec 16v vs 2.0 and 2.2 16v EW10/EW12: which engine is more reliable?
According to our risk index, the 2.0 and 2.2 16v EW10/EW12 carries less risk than the 1.6 and 1.8 Ecotec 16v: 14/100 versus 23/100 (both low risk). The 1.6 and 1.8 Ecotec 16v has no documented serious faults; the 2.0 and 2.2 16v EW10/EW12 has no documented serious faults.
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the 1.6 and 1.8 Ecotec 16v reliable?
The 1.6 and 1.8 16v Ecotec (Z16XER/A16XER, Z18XER/A18XER) that Opel fitted between 2005 and 2015 to the Astra H and J, Zafira B, Vectra C and Insignia A have a reputation as reliable naturally aspirated engines: the sources consulted document no serious faults or failure patterns, only minor problems such as ignition coils and, on the 1.8, leaks from the oil cooler or thermostat.[1][2][3][4]
See the 3 of the 1.6 and 1.8 Ecotec 16v faultsIs the 2.0 and 2.2 16v EW10/EW12 reliable?
The EW10 (2.0) and EW12 (2.2) are naturally aspirated 16-valve petrol engines with a timing belt, which PSA fitted between 1999 and 2010 to the 206, 307, 406, 407, 607, 807, C4, C5 and C8, among others. According to owners there are no frequent internal failures: the most-cited problems are the ignition coils (the only fault also reported by the press), the exhaust and, on the 2.2, oil consumption.[5][6][7][8][9][10][11][12]
