Hello your car lover out there! I am very desperate at the moment. I call my car Opel Omega 2,0 Limousine, “Dicker”! That’s the way to the beginning 🙂 This said Opel Omega is Bj 1992, 2.0 l machine, top maintained, Grarage vehicle has a probably since a day cylinder head problems:-(. Concretely: it was the 4 spark plugs changed and the cables. Yes! But then the bitter message: The 4 cylinder does not build up any compression. The spark plug was like new. I have not yet had the upper engine opened. So I am not 100% sure if it is the valve, cylinder seal? This vehicle, my dick is absolutely heart grown up to me. I don’t want to let it rot or the like. We have been known for 13 years…Bin proud of it 🙂 What would you do? p.s. Cylinder head seal? Very dangerous. Whole engine block? Ujujuj, but this will all be very expensive.
