Cracked spark plug

I changed out my plugs and wires and was still in the process of chasing down a bad miss when I noticed that one of the new plugs was sparking down the sides to the engine block. When I pulled the plug out it was cracked from top to bottom in three places. What the heck would cause that?

Re: Cracked spark plug

It could have happened when installing. The socket must have a foam or rubber insert to help prevent this. and keep the plug in place. If the socket tilts just a little it will break the plug.

Re: Cracked spark plug

Drop a plug...dont waste time throw it away....hence why I have old carpet under the car...also soaks up oil spills and makes working underneath comfotable

Sometimes suppliers are careless and drop a box of plugs

I have never broken a plug because of no foam inside the socket...those who do, the prime reason is because they have not seated the scocket full on and square on the plug

My Spelling is not incorrect...it is creative

Murphy's Law dictates that when you pull the foam lined socket off of the spark plug, the foam sticks to the plug, not the socket. When you pull the foam liner off of the spark plug, you drop it, and it never hits the ground. It has most likely fallen into some crevasse in the subframe, never to be seen again.

LOL Al, I know what you mean.

When ever I use somebody else's spark plug socket and the foam or rubber insert is missing it bugs me lol. I've had my Snap-On plug sockets for about a million years now, and the rubber inserts are still intact.

I like to be able to turn the socket upside down if I have to, and have the plug stay and not drop IT to the floor or some other nasty place.

Re: Cracked spark plug

...or what's more likely, you need a deep 5/8 or 13/16 socket, and the only one you can find has that #$#@#$%$ foam rubber in there, so you grab a screwdriver and fish it out.

How many still have the Craftsman magnetic socket inserts that - along with the microscopic allen wrenches - made up about 75 pieces of the 96 piece mechanics tool set?
