you have asked the question but you already know the answer, what would u like me to say based on the information you have given
have u checked coolant hoses ?, have u got a hole in your bonnet causing water to come in, do you think it is conceivable that it could be condensation as a result of a leaking camcover gasket
is it coolant or water, does it leave a sticky oily residue on your hands after it evaporates
is it concievable that such an amount of water would enter through the coil pack and near enough tight rubber seal to the plugs
have u tried using the search facility and find the most common cause for water accumulation in the spark plug recess when u joined the forum about an hour ago
usually cracked water jacket

personally i am surprised she still starts up as water and electricity dont mix and it could cause further damage to your electronics
