What happens when a spark plug breaks off?
Let’s say you are working on a simple tune-up and during spark plug removal, one breaks off below the hex, leaving the threaded “shell” stuck fast in the head. That can happen with any spark plug but most frequently with the smaller 5/8″ hex size.
How long does it take to repair a broken spark plug?
As the screw extractor goes deeper into the broken spark plug, it unscrews the broken spark plug at the same time. In about two minutes, out comes the nasty broken spark plug. I did it and it didn’t cost me $2000.00 dollars, I spent less than $20.00. I put in a new spark plug and my car is good as new.
Where does the spark plug go in an engine?
The spark plug doesn’t go anywhere that it can fall through a valve, because that’s not how an engine works. The valves cover one set of holes into the cylinder (carrying air and fuel), and the spark plugs go in completely separate holes (which are sealed by the plugs).
How is the condition of a spark plug determined?
Signs of fouling or excessive heat must be traced quickly to prevent further deterioration of performance and possible engine damage. An engine’s condition can be judged by the appearance of the spark plug’s firing end.

How does the gap on a spark plug work?
A spark plug has a relatively simple construction and is nearly maintenance-free, except for the adjustment (gap) of its electrode and periodic cleaning or replacement. Setting the gap on the spark plug electrode determines the voltage length and duration of the spark. A spark plug that has an improper gap will show certain signs and symptoms.
