What causes a spark plug to go out?
Symptoms: Maybe caused by a foreign object in the combustion chamber or the piston striking an incorrect reach (too long) plug. Causes a dead cylinder and could result in piston damage. Recommendations: Repair the mechanical damage.
What causes oil to leak from the spark plug?
Oil can also leak to the spark plugs through a faulty piston. Pistons operate at high speeds, and they are subject to wear and tear. Likely the piston rings, if there is a crack, damage, or a melted piston, the oil can find its way there onto the spark plug.
When does a spark plug ignite a piston?
The spark occurs when the charge jumps between the spark plug electrodes, just 0.01” to 0.07” (0.25 mm to 1.8 mm) across. The heat generated, between 8,500 °F and 11,800 °F (4,700 °C to 6,500 °C), ignites the air-fuel mixture, driving the piston down in the power stroke How can you tell if your spark plugs need attention?
What causes a cylinder to misfire when the spark plug is worn?
Misfire – A cylinder misfire occurs when the spark plug can’t ignite the air-fuel mixture. This can occur because of worn spark plugs, contamination, cracked spark plug wires, or other problems. Check Engine Light – For many people, the check engine light might be the only sign your engine is having spark plug problems.
Is it possible for a piston to hit a spark plug?
Feb 21, 2008 please excuse the poorly drawn diagram, but as you can see there is no way (unless your piston is in pieces) that it will hit the plug. it may be out of time and hitting valves. Just an Fyi… this is where you said it could be timing. 201 8 Mar 9, 2002

Can a spark plug be stuck in a cylinder?
I don’t think the part is stuck between a piston and cylinder wall. The normal piston to cylinder wall clearance is from .003 to .008 of an inch (it can be less or more depending on engine, components, intended use etc). The piece that broke off would have to be very small and land perfectly for it to be wedged in this small gap.
What happens if your spark plug is too short?
This could not only shatter your spark plug into the piston, but shatter the piston itself or damage the head. A spark plug that is too short will cause your engine to buck. The spark won’t ignite your fuel correctly and can cause poor gas mileage, plus prompt your check engine lights.
