Our customer drove her 1997 Explorer, 108,000 miles, 3/4 to mile & died on her would not start. It had no spark so we put coil pack in it; then no compression & we fould ALL the VALVES were PUMPED UP stuck WIDE OPEN. We are replacing the valves, has anyone expereinced this problem or knows why the valves would be PUMPED UP and stuck WIDE OPEN> Would like to know why, so we will not experience further down the line to prent this from happening again.
Please respond back with any ideas.
