I got home from the river last night, and went to town. Was just going to get started...ended up gutting it like a fish
So, that was interesting. It's a slanted configuration, means no normal jack will support it well, and I feel no need to make Daihatsu tool#xxxx. Screw that.
Drill some extra holes in the 1/2 inch plate back of a cheapie stand, not balanced, but not real heavy to spin either.
Hard to see in this pic, but light scoring and some rust colored pitting...not bad enough to catch a finger nail, but not good either. A light hone and new rings and that should shape up nice.
Big valves for a tiny motor. On the right, that elongated passage is the oil return to the pan from the valve train. I really think this was the main issue. The head gasket seemed to be "weak" where the the fire rings for the two cylinders meet, and continuing down to roughly the 2 o'clock position on the lower cylinder. This would explain the smoking, as on intake it may draw oil in, and compression would pressurize the crankcase.
I'll know more tomorrow after things a cleaned up a bit more.
