just got a 95 banshee, and t has a few problems. the thing that worries me is a small oil leak from the bottom of the engine case, theres a hole(from the factory) that goes in the case about a inch, and theres a small leak from it. its not threaded or anything but it is leaking slightly... and it has no coolant overflow bottle that i can find.. do i need one and whares it soposed to be at?
