Ring gaps are not that critical as some might think. Reason being most of the compression rings are deep in the ring lands. It leaves very little open area if you look at it it's area. The second ring is an oil control ring as well as a compression ring. The oil ring is a ser ring in essence. It ses the oil clean of the walls and transfers it to the open area between the expander and the second se on the oil sets. So years ago i found out that the second ring gap had to be at least the same and or bigger than the top ring. This removed pressure build up behind the ring up to the first ring. Years back it was always the opposite. The second ring always was much tighter in gap as we believed it ran cooler and it did. The second ring would not butt because it ran cooler. But it would not relieve the pressure between the second and top ring. So i startes opening up the gaps on the second ring. This in turn made more HP and it is now industry standard. See how things change. But i have tested Gap less rings and by now you know i worked with sealed power engineers quite a bit in the old days. So gap less rings came along. I do not like them one bit. They sound good but in essence they are counter productive. They make higher vacuum pressures and tend to suck more oil past the other 2 ring sets. We found this out with our blower and turbo motors. Actually they are not gap less. They have a double ring set in the upper compression ring 180* apart. Funny years ago my dad and myself used to machine the ring lands when they were worn out and install a buffer ring under the effected ring. basically making a gap less ring. This was common practice in the old days.
Hay stacks i am not trying to pound you. I thought about it last night and maybe you just dont explain things correctly. Please dont think i am trying to mess with you. Sometimes i have to read you several time to decipher what you might be talking about. And as far as experience i have a lot. I am OLD. This is what i have been doing all my life. I never worked in any other field. I also have a masters in mechanical engineering. You know an engineering educated know it all. If i get out of line i truly mean no harm. And be free to let me know. Dont take my bs fire right back. Thanks and have a happy holiday.
Staks here is an example of how things change. I had a bad hernia years ago at my belly button. The doctor operated and i was out of commission for 8 weeks. Last year i had a double hernia. The doctor put 3 little holes in my GUT and installed Kevlar mesh. 4 Hours after the operation i walked out and went home. 3 days later i went to work to do just paper work. And 2 weeks later i was doing small jobs. Also no stitches they glued the holes SHUT. Technology is it so GRAND!!! Things change. Once again sorry if i pissed you off. I have actually learned a few things from your posts.
