Is there supposed to be an o-ring or something like it on the tube where it fits into the engine block? The fit is snug, but the oil is escaping and coating the block fairly efficiently.

No o-ring or seal there. It should be a snug fit so if it isn’t it may have been removed one too many times! Check your filter hoses, though, as they could be the source of the oil. The filter appears to be aftermarket as the stock one probably had steel lines and was mounted in the two holes visible on the head in the photo.

Yank it out, clean it and the hole thoroughly, coat the shank generously with medium Loctite and tap it back in. There is likely a baffle on the bottom to shield the tube from crankshaft spray. The lower tip of that baffle should point away from the crankshaft. Then go do something else for a few hours.
