Well I was driving my 87 240 home from work today when all of a sudden there was some vibrating and a loud noise. No dash lights came on so I limped it to the off ramp thinking it was a flat tire, got out to inspect and found that all of the tires were fine. I went to start it up again and it sounded like a straight piped tractor. I didn't want to investigate too much on the side of the freeway off ramp so I got it towed home. Once home I popped the hood to check the oil which looked fine, go to check the plugs only to find one of the spark plug boots just dangling, yep blew a spark plug right out of the head. Checked the coolant and it's mucky. Pour some out for my baby guys, shes dead for now
