How do you get the metal out of a spark plug hole?
The only thing you can do to get out the metal shavings from the cylinder without removing the cylinder head is to use a long air hose pressure probe into spark plug hole and blow air into cylinder to try and blow the debris from the cylinder.
What causes metal shavings on spark plugs?
psychlow. If your plugs are white and have pieces of metal on them, it is because you’re running too hot (lean). Parts of your pistons or head are being melted or breaking off, and they’re accumulating on the spark plug.
What is the metal case of the spark plug used for?
The metal case/shell (or the jacket, as many people call it) of the spark plug withstands the torque of tightening the plug, serves to remove heat from the insulator and pass it on to the cylinder head, and acts as the ground for the sparks passing through the central electrode to the side electrode.
How do you get metal shavings out of a cylinder head?
Water will be just fine as will compressed air and brake or carb cleaner or a combination of the above. Just try to dry as much water out as you can before refitting it. As you say it should boil off when the engine gets to operating temp.
Can I clean spark plug hole?
With the plugs in, wrap a rag around the end of a screw driver, spray rag with some carb cleaner, then wipe around the plug and get out as much gunk as possible. Then remove the plug and as Dennis recommended vacuum out any loose debris. Then get the rag and screwdriver in there again and keep cleaning until satisfied.
How do you remove metal shavings from a cylinder head?
You could use an air compressor to blast air into the cylinder through the spark plug hole. If all valves are closed, the air will come back out the spark plug hole, hopefully bringing any metal shavings with it. If the exhaust valve/valves is/are open, the air should blow the metal shavings out through the exhaust.
What are the eight common parts of a spark plug?

Can I put Marvel Mystery oil in my spark plug holes?
It is touted as a fix-all for automotive problems, but it’s only 20 weight oil with some coloring put in it for “mystery.” It is not harmful if properly used. Putting a teaspoon down the spark plug hole before storage and giving the engine a couple of revolutions isn’t a bad idea. Engine oil would do just as well.
