It depends on where the plug is broken off.If just the ceramic part is broken you can just attach the socket to the lug and remove it normally.If the nut is broken and the rest is lodged in the hole you would use an ez-out.It threads into the remaining piece counterclockwise and when it bites into the remaining piece,it will thread it out of the block.Alot of auto parts stores have tools they will lend you to do this or you can buy an ez-out big enough to handle the job.
Why would you want to put a broken spark plug back in your lawnmower? Get a new one!
If they didn't have the tools they would stop and live where they are or if they did have the tools they would use an Axel.
the engine is constantly vibrating and it dislodges the spark plugs
I would think not. The timimg belt correctly times the ignition to allow the engine to run. No spark would have to be a problem in the primary or secondary ignition system componets. However a broken timing belt would not allow the input of ignition componets due to lack of rotation.
There would be six spark plugs for a six cylinder engine. One for each cylinder. Unless it is a diesel, then there are no spark plugs.
Broken timing belt? Jumped time.
bad spark plug wire.
The normal causes for a misfire would be Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another. Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings
That would depend on which engine you have in your 2003 Ford Excursion : The 7.3 liter diesel engine doesn't use any spark plugs The 5.4 liter V8 engine has ( 8 spark plugs ) The 6.8 liter V10 engine has ( 10 spark plugs )
Possible electrical short. Are the spark plug wires old or the insulation broken? Does all the other electrical accesories work? If not, there is a general electrical short somewhere, but otherwise, it probably has to do with no spark at the engine.
possibly a broken or missing engine mount
If the timing belt was broken, obviously the engine would not run. If you crank the engine and the distributor does not turn, that would be a good sign.
