I would suspect that Fred wasn't inherently meaning the piston itself struck the plug, but that the piston is the moving part that would cause the strike.
Yes, it's quite possible for things like a broken bolt to go down the intake, get sucked into a cylinder, bang around, and then get thrown out the exhaust. Tends to rattle like mad while its happening, sounding like you've got a bad wrist pin or horrible valve clatter. The bad side of this is that a broken bolt tends to beat the heck out of the head, the piston, cylinder walls, valves and valve seats. If you do a compression test on this engine, I would not be surprised if you find this cylinder is low on compression now. >>> "Greg Rowe" <[EMAIL PROTECTED]> 06/03/03 01:39PM >>> >From: "Nolan Penney" <[EMAIL PROTECTED]> > >If you mean the outer electrode had gotten smashed down onto the center >electrode, something hit it in the cylinder. > Thanks to Fred and Nolan for their replies. It WAS the outer electrode that was bent down and the consensus is that something hit it. Fred suggests that the piston made contact, but would that suddenly happen after thousands of miles and tens of millions of engines revolutions? The other thing (that I didn t previously mention) was that at the same time, I noticed that one of the non-stock bolts holding on my air cleaner housing had sheered. Does it seem possible that a small piece of the bolt worked it s way in the combustion chamber, bounced around long enough to bend the spark plug electrode and then exited? (at least, I sure hope it exited). ----------------------------------------------------- The information contained in this communication may be confidential, is intended only for the use of the recipient named above, and may be legally privileged.
