[89supra323]

hey guys, im sad cuz sumthing happend 2 my 89 supra. I needed new brakes so we lifted the car and changed them (all four, front and rear). afterwards my friend told me to turn it on, on the air to see how they sounded, so i did and then he just starts screaming "turn it off!" and when i looked back there was a huge cloud of thick white smoke coming out of my exhaust so i popped my hood and check the oil but there was no water in it. then i looked around and noticed that my brake oil and power steering oil overflowed and was all over, and my the part where my headers and that "catalytic converter look alike" thats viewable before the catalytic converter, was also wet. please tell me i didnt mess it up! thanks guys.
