This is Piston #1, 900 miles since rebuild.
Do the experts consider these rings worn in enough to be considered seated?
Or, due to the limited edge polishing, consider these unseated?
Is this what unseated rings look like?
Background:
Rebuilt engine in May, followed break in procedure. Start with SAE30 and new filter, after 20 minutes drained (& new filter) and filled with VR1 20W-50 Oil for 38 miles, change + filter, ~850 miles on VR120W-50.
Still burning ~1qt/350 miles. I have run this engine quite aggressively to try and seat the rings, but it has not seemed to work.
When I pulled off the carbs, I found a lot of oil in the intake runners. I though it was the heads, so off they went. Turns out there was nothing wrong with them.
So that leaves the rings.
BTW, the rings did migrate. both upper rings ended up on the same side, and the oil ring rotated 90 to the other side. Can't stop rings from moving.
This is what they looked like when I installed the rings.
