3.8 Engine hydrolocked and going through this now...most likely the windshield cowl drain has a gap between where it mounts to the cowl with the three 6 mm bolts (above the plastic manifold on top of the engine)- that water is ending up on top of and working into the engine more likely in the rear cylinders closer the the firewall, just drained a gallon of water from the oil pan and took 6 spark plugs out when water came out of that last rear cylinder I removed them from...only then could i turn the crankshaft with a wrench by hand, before this the starter sounded like a loud BANG! when trying to turn it over.. I also had the car sitting for total 5 months and it had started fine after 3, but after 2 months more, this happened and ethanol in that gas could also have well separated to fuel and water too..so I drained the fuel through the schrader valve at the fuel rail test point, removed relay 207 and used a short wire to bridge contacts 3 & 5, ran the pump 15 sec on / one minute off to be safe from overheating...hope this helps.

Rain water doesn't get into the engine.

If you have water in the cylinder and the engine hasn't been submerged in a flood, then you have a blown head gasket.
