Buddy of me found a repair manual in which all 4 cylinder engines in the Omega B are treated. Now there was probably on top of it: 1.8L 4/94 – 9/94 Now the question is whether these 5 months there was a 1.8 in the B Omi. Had a certain rarity value… In the Astra there was also once a few months the 1.2 three cylinder. But was stopped due to lack of sales numbers.
