My car had been leaking and after lots of work realized it was a leaky bypass elbow (that goes from tensioner to intake) so after having that replaced and its still leaking we realize that from putting water in the car over the winter (coolant leaking out fast at $10gal) the engine has a small crack in it. Dude told me to use Bar's and if it stops leaking its ok. Well the Bar's didnt work and now its not overheating but still leaking slowly and I really need to drive it... What will happen if i do? I have a small child riding with me and need to be safe yet dont have money for new car or new engine
