just got a 91 SHO and the power steering is very noisy. whenever i turn, i hear the noise. i checked the power steering recevoir and it was kind of low. does anyone know about this problem? they say it was common on the 91's. if i steer too much to the left or just steer, i'll see some smoke coming out the engine, any advice would help, this car only has 73K and its a project car, i need it to be in top shape.
