Water in Oil
If the water got in during the water wash, the only way into the pan is past the rings....... if a significant amount of time has pasted since she got the bath, you can bet the water sat, and some may still be, sitting on top of the pistons, and the rings are rusting as we speak. I vote pull the plugs and blow the holes out with compressed air. If/when you find holes with still water still in them, you'll have to make a decision...
