It's when it quits leaking is when I'd be concerned
...did I forget to put oil in it.[S.......I am a carshow junky...I have been in more carshows indoors and out that I care to remember and at every show there are cars that leak oil from somewhere mine included...it's just part of the sport...at most indoor events that I have been at the officials come over to all the cars and hand out plastic sheets for you to lay under your ride....I know at some events that require you to push your car into the building alot will puke oil out of the power steering leaving a trail of red fluid all over the floor....mostly Fords
....also on another note...I read a sign at a car show once that read....Rock Chips Give Vehicles Character....Boy does mine have Character!!!!If you want your ride to stay perfect....put it in a glass case....otherwise let her leak and have fun with it.
