I had the head gasket go out on my 5.8 liter v8. The local ford dealer replaced them for me. They told me it was running like a top and they drove it about 3 blocks and it died. They popped the hood and the passenger side exhaust manifold was glowing red hot. It had burnt the plug wires in two. They told me it had a clogged Catalytic converter. I disconnected the muffler/converter and drilled it full of holes to insure airflow. I replaced the plug wires and attempted to drive it to a muffler shop 8 blocks away. The motor would run but would not rev up and acted like it was towing a freight train. I wasn't able to go over 15 miles per hour. I arrived at the muffler shop to have the CAT removed and discovered the motor had burned through the plug wires again and was glowing red hot again. I have taken it to 2 mechanics and they have no idea what is wrong. I do know that it IS NOT the Cat/converter. I thought it was timing, but the mechanics assured me it is not. The back 3 cylinders on the passenger side are running about 150 degrees hotter than the other 5 cylinders. I need help. The motor has been well taken care of. It is not worn out. It was running perfectly when the gasket blew. It did not get hot. I'm not sure what would cause this. What went wrong on my gasket repair for it to have messed up so bad?
