First off this is the first gas vehicle, and car, I've ever owned(others are diesel). Its a 1995 Mustang GT. The car has 87K on it and it runs good. It has some kind of hurst shifter, underdrive pulleys, 65mm TB, CAI, shorty headers and different spark plug wires. It has no cats on it, just mufflers. Today I finisished the smog delete. It aslo has like polished fuel rails that have ford engraved in them and I didn't know if these were aftermarket or anything? Now to the problems! It leaks oil in from the front and the rear of the engine(I'm goin to have this fixed in the spring). The AC/Heat only blows from the defrost no matter what the selector dial is on, does anyone know what could be the cause of this? Thanks and sorry for the long post.
