Reasons for rings not "Seating"

[tpunx99GSX]

Yeah i know the break in methods by heart, but i was just wondering why a ring wouldnt seat, and what a properly seated ring is? Never heard of the cylinder wall being too smooth. And Steve you bring up a new term What is 45 Degree hone? I deglazed the cylinder with a plate style hone on the cylinder that had the bad piston.
Also when i install the pistons, should i use Oil or the Lubriplate lube on the walls? I was planning to use the luberiplate stuff on basically all metal to metal contact.

Every ring manufacturer has a specific hone pattern, but for the guy doing a hone at home, it's best to have approximately a 45 degree cross hatch pattern. I prefer the bottle brush hone since it makes the patterns easily with a variable speed drill on slow moving up the down the cylinder pretty quickly to get the 45 degree pattern.

Use 30wt non-detergent oil. You want some metal to metal contact, that's what seats the rings. If you use some sort of assembly lube, the rings won't seat properly.

Thanks for the info, been a big help. Looked at the hone i did and it looks approx 45 degrees. so i should be good. main reason i did the hone was to get out a small nick on the bottom of the cylinder so it didnt scratch up the piston skirts.
Should i hone the rest of the cylinders while i have all pistons out or just return them to their old locations and call it good?
