A reasonable amount of oil usage is not necessarily a bad thing. When I was building engines for my race planes we always set them up to use a bit of oil for extra lubrication under extreme temperature and stress situations.
Only fly in the ointment I see with yours is that it only smokes on one side, A bit curious, but still not something to worry about if everything else checks normal.

Thanks.
Looking to get in under the plenum and have a few things addressed, so if the is something doable, I?d like to figure it out. Otherwise, it does run well.
