I think that is also why you have water in one cylinder, but not in all. If the water was really clean, the damage might be not that bad.

Primary problem in that case are the piston rings.

If the water wasn't clean, than we have a bigger problem, because all the debree is in the engine and that will cause major problems. So our major problem is not only to get all water / huminity out of the engine but also all debree.

In general i would say it's safer to rebuilt the engine; or at least pull the heads and oil pan etc. and clean everything up, just to make shure possible debree doesn't eat up the engine. As you know most M96 parts are made of alloy, not steel.

Hope weather conditions get better soon. But if you can work in a t-shirt it might be not that bad. Over here in Germany we have snow and below 40 degrees F. So no t-shirt weather.

The valve openings are only so big from a debris point of view.

It seems like you could vacuum out the cylinders through the spark plug hole
anything else left is likely to be harmless or disintegrate quickly.
