just put in a new motor in my fuel injected 93, the motor came set up for a carb but I put my FI intake on it. my most recent problem is i forgot to block of a threaded hole on the side of the oil pan. it doesn't look like the sensor on the side of my old motor (low oil i beleive). the hole is threaded on an inset panel that appears to be rivited onto the pan, whatever would go into that hole would almost stick straight up. does anyone know what goes in there and what i could ude to plug it? i tried a 3/8" pipe thread plug from the hardware store but it felt too big, a 1/4" felt like it would fall right through. any ideas? by the way the new motor has trick flow heads and is supposed to make 400 horse, trying to get the car ready for my brothers wedding next saturday.
