"Hello again,
I pulled the head off of my Force 70, and found two damaged pistons. The #2 has 3 ripples in it along the edge, and the #3 has 2 ripples in it. Looking straight at the damaged areas from the tops of the pistons, I can see the rings, but neither of them had any parts fall off. #1 looks fine. Luckily from what I can see, it did not hurt the cylinders, and the 45 degree honing marks are still there.
My question to the experts is, what would have caused this kind of damage to the two pistons? Could something have come through the ports that would have caused these ripples in the pistons, or could overheating, predetonation or lean gas have caused it? Before I start buying pistons, rings and gasket sets I want to get a good idea of what I should look for so I don't neglect a problem in an other area and have the same thing happen again.
Just another quick note, I would like to thank everyone for their input on this forum. I am learning a lot by just reading some of your feedback on other issues, and this board by far is the most informative one I have found. Keep up the good work!!!
Thanks,
James"
