The noise got louder when we accelerated. We drove the car home slowly, and parked it. When we checked the sparkplugs, we found that one had detonated within the third socket, and it drove part of the sparkplug into the wire. We replaced all 6 spark plugs, as well as the plug wires. Just to play it safe, we vacuumed the cylinder to get any of the ceramic out. Started the car and the noise was still there. Checked the Haynes manual and it looks to be the pistons. Tried to start the car recently to have someone hear it and now it won't start at all. Do you think it could be the piston springs? There has to be a reason for the spark plug to detonate. Prior to all this, we had to replace our radiator and hoses as the radiator cracked in the upper tank. That was replaced along with the thermostat to play it safe.
