Yesterday when I was running it to adjust the idle, before putting it
in the water today :-( , everything was fine then, all of the sudden
quite a bit of black smoke came out and it started blowing steam. Did
I just witness a head gasket letting loose?
I'm really hoping that's the case instead of a cracked head or block.
I checked the oil this morning and it has a green hue with the level
way up, about an inch above full. I didn't bother checking the coolant
as I figure it went up in steam or is currently sitting in the oil
pan.

Thanks
