Re: How bad do my pistons look?

Using my dry compression test results as starting point (#1 - 121 / #2 - 90 / #3 -120 / #4 - 118 / #5 - 119 / #6 - 120 / #7 - 118 / #8 - 120) I removed the #2 piston - the top ring was toast and land were shot - I'm surprised I got a 90lb reading. The connecting rod bearings and wrist pin were in much better condition than I had expected

I was doing a bit of research before measuring my piston bore wear and read that the oil fill tube can come into contact with the crank if not installed at just the right orientation

Being that I had removed the fill tube I removed and inspected it and sure enough a new shiny spot witness mark.... so, that's the source of my tick!!
