Gotta have to agree on that. Anyway, since the humidity embedded in the intake stream during a rainy day actually retains more residual heat that would otherwise irradiate through the cylinder liners to the cooling water jacket (or the cooling fins if we were looking at an air-cooled engine), it doesn't sound likely that any small amount of steam would condense and fall through the pistons. Steam also tends to go upstream, so it would also pick more residual heat from the cylinder head and eventually escape easier when the exhaust valve opens.
