valve guide clearance
Sure did. don't remember the actual clearance, but it was the typical just out of bounds number. I guess what happens is since the stem height is a bit small, the area gets too hot and wears the guide to a certain point and then stops. At that point, the oil flowing through the worn guide cools it to the point that it no longer wears. The seals replacement reduces this for a bit, but that's about it.
