Today, I went to drive my crossfire for the first time in 6 months (college,) and it would not start as the battery was clearly dead. Before jumping it I thought it would be a good idea to add some distilled water, while doing so I ended up dropping one of the screws into the depths of the engine... As a temporary fix, I put some tape over the hole,

Anyone know where I could get one of those screws, or if there is another way to keep it sealed?
