Hi people, have a question: My Omega was replaced by the engine. the dealer made it with which I bought it about half a year ago, fell still under the warranty. In his opinion the original engine (year 98, 156 000KM, 2.0L 16V Ecotec) had to go out because he was smoking out blue, and constantly an oil pool was under the engine. Cylinders had too much play, changing the valve shaft seals did not bring success, etc…. According to him the replacement engine was equal to old, 1. Han d, would have only 35 000KM, etc… can’t be, right? A 14-year-old engine with 35 000km? besides, it has a lot more flying rust on the thermal guide plates and Krumers like my original motor. The oil measuring rod is also different in the version,….. do not have a good feeling. How can I see how old the engine is and what kind of engine it is. Is that even a 2.0L 16V, why is the oil measuring rod different?? Would be totally great if someone could help me, am at the moment a bit perplexed… . 🙁 On the valve cover of the replacement engine ECOTEC is on it, like the old one. I count on you! Greetings!!!! Ciao I found the engine code now: 603150 X20XE 188688 (X20XE is the 2.0 16V, right? the other numbers still give information about something?) MERCI
