1.4 / 1.6 16v E-TEC II vs 1.8 T 20v: which engine is more reliable?
According to our risk index, the 1.4 / 1.6 16v E-TEC II carries less risk than the 1.8 T 20v: 19/100 (low risk) versus 32/100 (moderate risk). The 1.4 / 1.6 16v E-TEC II has no documented serious faults; the 1.8 T 20v has 1 documented serious fault, the main one being «Turbo wear and oil consumption».
The index (0–100) weights the severity and frequency of the three most serious documented faults. How it is calculated
Is the 1.4 / 1.6 16v E-TEC II reliable?
The 1.4 and 1.6 16v GM Daewoo E-TEC II (first-generation Lacetti/Optra and Aveo) have a timing belt and, according to the Polish press, a moderate fault record. Documented issues are faulty valves in the first units (2004-2005), lambda sensor faults and a few cases of oil leaks or oil consumption.[1][2][3]
See the 3 of the 1.4 / 1.6 16v E-TEC II faultsIs the 1.8 T 20v reliable?
With up-to-date maintenance, the 20-valve 1.8T has a reputation as a powerful, durable engine for its time, but owner reports document recurring faults: ignition coils (especially on 2001 to 2003 units), water pump and air mass meter, and less often the turbo -sometimes linked to growing oil consumption- and the timing chain tensioner.[4][5][6][7][8][9]
