Hello everyone. I’m the next with the cylinder head problem. 4.6 he Northstar. I had taken the car to a US workshop because it cooks constantly, especially at mountain ranges. A CO2 test was taken to exclude a cylinder head problem. The test was negative, so first of all good for me. Compression test was okay, pressed off, okay. Suspect was thermostat and water pump. So, let it do…. Then the nasty surprise! The car cooks exactly as before. So wi I think it’s the cylinder head screws, you hear and read a lot about it and that it’s a Northstar disease. If that’s what it is, I’d be happy about nice people who have already done such a repair and can help me. To throw away it’s way too nice. Year 94 and really a great car. Would be nice if a private screwdriver, the spas, would be of course, only the prices that are mentioned in the forum in workshops, I can not pay. I am also happy to join and help. Would be great if someone would sign up. The car is “due to driving” therefore a radius of 100 km around Frankfurt/Main would be still possible. Thank you very much. Greetings to all US car fans.
