#1 Mustangs are not boats!
#2 Take all 4 of your friends cars, and drive through the same puddle next time it rains!
#3 I've hear this problem before, a wrist pin, or a rod bearing could definately be the cause. Does it happen at all RPMS, or at certian RPM? If it happens at a certian RPM, I would say its a rod bearing before a wrist pin, but you never know.
Good luck!!!!
