You have a lower compression reading on one cylinder. Did you perform a wet test on that cylinder? How about a leakdown test?
I see insufficient diagnosis before you pulled the engine down, possibly unnecessarily.
I would say you have some valve seal issues, and/or worn guides.
Valve guide lubrication is a "catch 22", no lubrication gives worn guides, some lubrication gives good life, too much contributes to high
oil consumption.
