dutchhotrod- quote from first post "No vacuum leaks. idles very smooth after setting the air/fuel idle screws as directed". this is his quote, so i don't see why everybody is trying to give him a intake leak. if he had a bad enough intake leak (top or bottom) to be sucking enough oil into the cylinders to foul the plugs out, i assure you it wouldn't be idling good.

ps- dutchhotrod, you need to find something better than gas to be spraying over the motor while checking for vac. leaks.
