The rings used are not even up to factory quality.
I see only a Moly top ring on those pistons whereas the factory rings were a far better Moly face top and second ring.
The rods are old type, that still have the unnecessary oil spurt hole in the parting line of the big end.
Molly face rings need to be installed very carefully so not to scratch their face or the cylinder wall finish. A smooth finish must be what’s needed for such a ring face.

"Why did the Top Compression ring Break into uneven parts anyway, on about 5 combos of Piston and Ring sets?
