So many oil leaks.
Even had oil mist out the windshield defrost vent!
What causes so much oil around the cylinder/case interface?
Pretty wet on both sides.

Side where I attached the oil breather to air cleaner has built up oil on back side of intake valves!!

Have to figure out a better way for head and case vent.
On a positive note, 6 8 6 6 % leakdown!!

check you head bolt torque, if you have good leak down and compression was good, then rings should be ok, but you’d get some oil leaking by case/cylinder interface over time the loosen- 4 years ago when i pulled mine to paint, mine were only 12-15ft# should be 25 or 27# i believe, no leaking after that-
