Well, maybe I didn't explain the intake right, when I said raised runners- i mean raised up seperate from the valley pan. You can stick your hand under the carb. & wiggle your fingers. That's where the oil gathers- never said it leaks from the bolts under the carb( as in the ones that hold down the carb) but it will leak from the intake bolts, as well as front & rear valley pan seals, and still run.
