I know it's not the dipstick tube, we pumped the oil / water our of the
dipstick tube when we winterized it.

It may be an oil drain kit like you said, but it doesn't line up with
the bilge drain plug at all. It comes out the side of the oil pan and
goes up, terminating in the wider section I tried to draw in ASCII.

We pumped the oil out with an electric pump through the dipstick tube
(my dad owns an auto shop, and is as puzzled by this tube as I am). I
did check the oil level, and it DID show over full. Color me an idiot


Thank you for your help. As long as the tube ISN'T a breather, I'm
guessing we can plug it with a piece of foam to keep water from pouring
into the oil pan (and spreading a lot of oil over the bottom of my
bilge compartment in the process).

BTW, any bets how long this motor will continue to run after being
lubricated with a 1:7 oil / water mixture for half a summer?

Are you sure you're not talking about the dipstick tube now?

If it's not the dipstick tube, it sounds like someone may have put an

oil drain kit on the engine, to drain the oil out the bilge drain
into a
waiting vessel.

How did you drain the oil?

Did you check the oil level at some point before draining it? Was it

over full? You indicate there was about 8 quarts in the crankcase,
and
the 3.0 takes 5 quarts, with a filter change.

Otherwise, there is no breather tube of any sort that goes into the
oil
pan. The breather vent is in the rocker(valve) cover.
