Squeaky sprak plug

[Rixster]

So, Had the strangest thing happen yesterday. Running a pretty steep hill through the pines, I hit the happy button and instantly drop one cylinder. Needless to say I got nice and stuck. Get out and back to the bottom, still running on one cylinder and something is squeaking like crazy. Sounds like a rod bearing or crank bearing or something bad. Pull plugs and sure enough one is firing and one is not. Swap plugs from side to side. Still runs one and squeaks bad ! Take one plug cap off, fire sled on one side adn the squeak is gone. Shut it off, take that cap off and put the other on. Sled wont start. Put both caps on, sled fires on one and the squeak is back !! So I pull the plug on the side that is not firing, put my thumb over the plug hole and have a buddy pull it over. Tons of compression !!! blows my thumb off the plug hole. Well what the hell lets put a new plug on that side. What do you know fires right up on both and the squeak is gone! NO WAY. Put the "squeaky plug" back in just to see and sure enough sled runs on one and the squeak is back. So anyway, Have any of you ever seen a squeaky spark plug? I did ride the sled for about 5 hours after this all happened. Ran great all day !!

I have seen Plugs leak compression between the ceramic and the metal base but not in quite a while mostly a problem with Champions cus they used a paper packing instead of fusing the two together !!!!!

I have seen that when a plug breaks after a roll over. Weird that it would do it without something hitting it. You said you were in the trees and if you ride the trees like I do, bouncing off of them, maybe a branch whacked the hood hard enough to break one.

Detonation cracked your plug. You need higher octane fuel.

Hmm, that never crossed my mind. I bet your right. I am running 111 in my nos fuel bottle. (I have a separate bottle of fuel for the NOS) It was the first time i hit the button that morning, I bet there was some air in the fuel line. That would make sense to me! Looks like I better purge the system before using it.
