No benefit to having oil in the intake. In fact just the opposite. Ford Performance recommends an aftermarket oil catch can, especially if you track the car. FP has one available now but I use the UPR system. I'm surprised they just don't include it from the factory but I would recommend adding this. They collect a fair amount of junk. Again especially if you track the car.Are you concerned about the oil? Based on the nature of the engine it might be normal... Are catch cans necessary ive had them on my turbo cars but they keep the oil out of the intake track? Any benifit to having oil there?
