In fact, I always thought that leaking valve seals only leaked "a little bit" from gravity after the engine was off anyway...and smoked a bit on startup.
SOooo, it would seem that the oil must entering the flow before the exhaust valves rather than after them. Right?
Still sound like rings/piston/cylinder?
Not sure how I overlooked this little bit o' fun for so long...
Anyway, now that I've seen it, I'll throw in my 2 cents.
First, a leaking valve seal can have various symptoms depending on just how much they are leaking. At any rate: if the rings aren't sealing you can burn a whole lot of oil in a hurry, if that's coupled with leaking valve seals, carbon CAN build up pretty quickly and start blocking valves from seating.
Second, I didn't notice anywhere a mention of cross-hatching on the cylinder walls...
Last thought, I don't remember how much more you bored it, but thinner cylinder walls can flex quite a bit and make the whole thing worse.
I'm interested to see how this whole thing turns out...
BTW, welcome to the club
