So this 68 Ghia has been sitting out in a farmers field for 10 years (yeah I know). I just got around to draining the oil so we can drop the engine and get it on a stand for rebuilding. The oil came out looking like chocolate milk and smelled horrible.

Water... You'll likely have some rusted parts in there too.

That's funny you said that because the half quart that drained out was water, then the oil started flowing.

Wow! That's the first time I've seen a "chocolate milk shake" in an air-cooled engine! That's what you usually see in a water-cooled engine when a gasket blows and water gets into the crankcase.

Bout the 100th time I've seen it. Call it chocolate milk. It's not hard to clean. Suspect coolant leak. (just kidding)

Even if the engine was protected from the weather it will build up condinsation inside. This is what happens in a damp area. I have rebuilt a couple of engines like yours. The one was rebuilt not long before it was left to set.. All parts cleaned well, but did not look very good when done. Dark spots from rust, discolored bearings, ect. But everthing measured out OK and looked usable. New valves, springs and a P/C kit put it back on the road for another 75,000 miles until I replaced it with a larger engine.

I recommend changing that oil.
