Piston Failure
That pressed together material won't take much punishment
That was my experience as well, just wanted a second opinion.
And there ain't a lot of fire-ring support in that direction as well.
My FelPro 100xs are on their third install;" if you don't try it, then you'll never know"; I said to myself. The least amount of pressure they have seen is about 175psi, and they now have probably over 80,000 miles on them, but probably less than 100,000.
IMO, they are gold no matter how much they cost, and the cost per mile for me is so cheap right now, nothing else I have tried can touch them.
Thanks for responding in detail.
