Removal of Difficult or Stuck Spark Plugs


Recommended Posts

Interested to hear from other members any tricks or tips for removing spark plugs. One useful tip from a YouTube video was to use a length of rubber tubing to grip the spark plug which makes it easier to remove from a deep recess in the cylinder head.

My main issue was trying to remove a long life iridium plug which has probably been fitted for about 5 years. I was only able to turn the plug about a 1/4 turn before it became stuck or very hard to turn. I used similar to WD-40 spray as a penetrating lubricant. After waiting a minute or so, I then tightened and loosened the spark plug but it was still hard to turn. Obviously not wanting to strip the thread in the alloy cylinder head, I then warmed the engine for a few minutes and checked YouTube for some hints. After turning off the engine, I gave the spark plug another good spray and waited a short time. Spark plug then turned a lot easier and was able to be removed.
