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."
C20XE/X20XEV 2.0
"Astra F/G, Vectra A/B, Calibra. C20XE = red top legend (16V). X20XEV = Ecotec successor. Timing belt (C20XE) or chain (X20XEV). C20XE is one of Opel's great performance engines. Reliable with care."
