Character

1.2 NA X12XE / Z12XE / Z12XEP / A12XEL / A12XER (Family 0)

"Simple 16-valve four-cylinder for the Corsa, Agila and Astra; lifespan around 250,000 km. The weak point is the timing chain and tensioner - avoid an early Z12XE without chain records, listen to every cold start - plus a leaky oil-pressure switch and ignition-module misfires."

X10XE/Z10XE 1.0

"Corsa B/C, Agila. 3-cylinder. Simple, fuel efficient. Head gasket can weep at high mileage. Timing chain. Low power but cheap and reliable city car engine."
