Well, I pulled the PC tonight. It does not have any cracks on the outside. The Ball Pin looks intact, no forign material, or major carbon buildup. It looks like burnt charcoal inside. I noticed what LOOKED like a HAIRline crack on the sidewall below the ball pin level. The tip on the GP side looks like white stoneish pitted and chipped away. The other side is smooth and blackish. Looking down at the piston where the PC was, it was not much to see. VERY black and soot covered, no forign material I could find.

Since I have the glowplug out, I might as well replace it. One less thing to die of old age.

I will post pictures of the PC and homemade tool later tonight when I can get at my digital camera.
