They all go where they want to go anyway once the engine is running and the reason for initial offset is to prevent scuffing on initial start, at least that's my understanding on V or vertical engines. Having a one piece oil ring gap at the top or in this case, the scraper gaps, makes sense on a flat boxer though and hope they don't rotate to the bottom. Make sure the expander ends are not overlapped and follow the mfr's. instructions on what side of the expander goes towards the top of the piston. Who made the rings? Have you checked the end gaps?

Thanks for the post.
3 and 9 for the compression rings - Is there any issue lining them up with the wrist pin? I thought Wayne’s book stated not to do that.
The rings are made by Total Seal. I read their
instructions and they do not appear to be specific for a boxer motor.
It looks like Total Seal is recommending: 6 (top) ,12 (2nd),10 (oil rail) ,6 (oil expander), 2 (oil rail).
I checked the end gaps, they were all within spec.
Thanks,
Dan
