Hello everyone, I’m new here in the Opelforum and I already have a big problem.My Omega 2.2 running tune 230000Km, needs Oel about 1.5 liters at 1000Km. If he has stood for more than 12 hours he only runs on three cylinders in the first minute which indicates a defective head gasket (water consumption).In addition, he makes noises below the exhaust manifold (rass).The noises do not change with warm engine. I’d rather have a second-hand engine that ran less. Does anyone have a tip? Greetings, Andreas
