Sporadic puffs of blue smoke out of exhaust.
Cylinder 1 shows sings of burning oil (plug oily).
Line from crankcase to pulse fuel pump gets cloged with oil. Pump stops working. empty line, reconnect and pump works fine until the line gets clogged again.
Pulled heads and noticed that breather reeds are broken (what are these things?).
Cylinders walls look good. Still shows signs on original boring hash marks. Rings look in good shape. Ring gap orientation not position correctly. Oil rings are correct.
Slight scoring of cylinder 1 connecting rod to crankshaft bearing in line with crankshaft lube hole.
No signs of burned valves.
Valve seals look good.
This engine will burn/blow thru all its oil in about 2 hours (low oil cut out kicks in).
Does anybody have any ideas?

Breather reeds create a one way seal for the crankcase. If the reeds are not sealing it will allow air to move in and out of the crankcase and will take the oil with it. Replace the reeds and see what happens. For the engine to operate properly you need a vacuum in the crankcase to contain the oil.
