It wouldn't be just clean air being sucked in like an exterior leak, but a finely homogenized mix of oil/air vapor that would be far more combustible than clean air alone. Just my opinion.

On the other hand, even if he does have an internal leak, I think the main culprits are the rings. I don't think I've ever seen a hone and re-ring operation that worked out great and I suspect that in this case, the new rings never seated, possibly due to an improper honing job and also possibly due to excessive ring end gap due to using standard overbore rings with a too-large bore. Again, just my opinion.
ive ran into this a lot of times on the GM 2.8 alum. intakes, which is bad about sucking the gasket from the bottom side. if you think about it, if the gap is wide enough for 10w40 motor oil to be sucked through it then, no i don't think the idle screws will take up that much slack. most of the time there is no ? about where the oil is coming from because if its being sucked into the cylinders it will smoke so bad you wouldn't drive it, and you wouldn't drive it long enough to foul the plugs out any way. any thing other than checking the comp. wet-dry or a leak down test at this point just dont make no sense to me. why would you pull the intake with out checking the comp?.
