Driving to work today and a loud bang happens under the hood of my Ford Expedition. Pulled over with the engine still running to take a look. Sounded like a blown exhaust gasket(or like the sound of backfiring through the exhaust). Drove it home.
Coil is blown off and spark plug is laying next to the valve cover. It's a Triton V8 which has a coil at each cylinder. I threaded the plug back in only to find that the plug hole is stripped. As Gene would say...Mutha Fu....
It's a 2003 and the engine has 130k miles on it. The plugs were changed at 100k. It ran great until today. What would cause this to happen? Maybe the plug hole was stripped when the mechanic replaced the plugs and it just now gave way?
What options do I have with this? Heli coil? New head? If anyone has one of these engines in an expedition, you know it is almost impossible to do work on the 4 rear cylinders since half the engine is under the front of the cab. I was going to call the local dealer to find out what they could do, but I wanted to check here first.
Just ain't my day!
