Original 948 pistons on the Bugeye were aluminum split skirt with 3 compression
rings and 1 oil ring (scraper) for a total of 4 rings. They were numbered 1 -
4. I had to replace mine because the bore was machined .030 over to clean up
the
oval at the bottom of the cylinders. I bought AE replacements from M*** that
were solid skirt and 5 rings, 3 compression rings with one oil ring above the
wrist pin and another oil ring below the wrist pin. Might be the cause of some
of the overheating due to more friction.
