Engine Performance problem
1998 Ford Explorer V8 Two Wheel Drive Automatic 158000 miles
Five weeks ago someone put something in the gas tank.I did not know so I started the truck and it ran for about a minute then shut off and would not start again. Mind you it would turn over. After sitting at the shop for a week. They pulled the tank. The gas was red orange with a chemical type smell. The engine was locked up. Pulled the fuel injecters. Ends are pink with a some build up. My question is should I pull the heads? If this motor locked up because of what was put in the gas tank and not because it was ran without oil or water. Do you think I will find it without tearing the motor all the way down?
