Spark plug blew out of motor - 1998 Ford Explorer
Inspect threads in the plug hole might be stripped, if so you will have to buy heelly coil spark plug kit to repair it also use shop vac with small hose attached to **** out any thread shavings that will be in there and once you are done before installing spark plug crank it over to use compression to blow out any thing vacuum missed.
The spark plug blew out because it was not installed correctly and was loose. Install a new plug and do it very carefully as there may be carbon in the treads the plug screws into. Screw it in until you feel it getting tight and then turn it back. Keep turning in and out until it fully seats. Always follow the vehicle manufacturer torque recommendations, but as a general rule 14 mm plugs with a gasket style seat should be tightened to 26 to 30 ft.lbs. in cast iron heads, but only 18 to 22 ft.lbs. in aluminum heads. Likewise, 18 mm plugs with gasket style seats should be tightened to 32 to 38 ft.lbs. in cast iron heads but only 28 to 34 ft.lbs. in aluminum heads. For taper seat spark plugs, 14 mm plugs should be tightened to 7 to 15 ft.lbs. in both cast iron and aluminum, while 18 mm taper seat plugs should be tightened to 15 to 20 ft.lbs. in both types of heads.
