Hey guys,

I was looking through some pictures that I had taken of my 307 after I had pulled it from my parts car. Well in one of the shots of a group of spark plugs (who knows what I was thinking?) there is what looks like an extender or something like that on the end of a plug. Also in a picture of the motor, the same plug is in the #2 cylinder. What is this this and why is it there. Could it be to make up for another problem?

Also, When we did a compresion check on the motor before doing the swap, the #2 came up a little lower than the others. And recently, on the same note, I have been having some problems with rumbling under the car and poor performance. When We changed the iginition and wires and plugs, we didnt put this extender or jacket looking thing on. Could this be serious. I am no engine internal specialist, but could this be bad rings on the #2 piston??? If it would help, should I put that jacket thing on the spark plug again. PLease help guys. I am at your mercy. Thanks

That "extender" is an Anti-fouler commonly used to keep a plug from getting oil fouled. Whenever a cylinder starts to burn oil it deposits gunk on the plug keeping it from firing, this helps keep it from contacting the plug so it will continue firing.......
