Hi together I hope someone can help me here. It’s about a y22dth 2001 Omega b Caravan with 161tkm. I bought the car with defective head gasket. Despite the damage the car jumped great when buying (-10°). According to the seller the car should go out at the operating temperature. What was the case even after about… 20-25 min.. After disassembly of the engine came out that the head gasket was defective at 3 places on 3 pistons. The car had with the old seal almost zero power. After the seal is renewed the car runs in the stand clean up to the operating temperature. at about 85-87° the engine goes out impactfully without pre-registration. The engine can be stopped immediately again and also jumps immediately again. But does it immediately also not jump again 1-2 times…. after a short time it jumps again and until reaching the temperature it goes out again. Keeps the engine constantly on about 3000-4000 turns it has super-up after 30-40 seconds of dispension.
