there is also an oil seperator between the heads underneath the lower intake. it has two tiny bolts holding it on and they work lose letting the gasket push out. the oil then builds up in the valley and will eventually run down the front of the engine and look similer to the front main or timing cover leak. I spoke to Terry Haines about this and he said it is quite common on all duratech engines. ditch the gasket, silicone it and thread lock the crap out of it if that is your problem. If you look under the throttle body down into the valley there is a coolant hose coming straight up out ot the block. if you see any oil around or behind that then youve found the culprit. clean the uim and lim while your at it.
