Jess......Well, too bad it wasnt something as simple as the fuel shut-off......but as you dig into it, it may turn out to be something minor. Good luck with all the work......and zap us some pics of the process.
Another problem with wet cylinder sleeves is that they get electrolysis pinholes, especially if run with poor coolant. I have seen this much more often than o-ring leaks. It will be easy to see pressurized with the pan off. If the piston is down, it will be leaking between piston and cylinder. If it's up, you'll see the stream.I'm with Shawneecat... Happened on my 207D case which is the same block. Could also be a rotted cup/freeze plug in the head. There are 3? right down the middle that separate the coolant inside the head and the oil on the rocker arm assembly. Also happened on the same engine as I am just that lucky.
When you try to start it again, drain the coolant from the bottom of the oil pan. Just remove or loosen the plug long enough to let the coolant out. This may save you a lot of money in bearing and crankshaft work.
