Well I have to take my car to the dealer finally. After owning Mustangs for over 7 years, this will be the first time it has to see the shop for mechanical repair. I noticed a few months ago a little bit of oil on the valve covers, but I couldn't find any visible leaks or anything like that, so I figured it just spilled a little bit at one point when it was being poured. Well today I was showing off my car to my uncles and had the hood open and I had revved it up a few times. We noticed the oil kinda all over the engine bay and then sure enough, I noticed a bit one the outside of the car on the fender. It is spraying out of a sensor at the front of the passenger's side valve cover. Has anyone else had this problem? Also, which sensor is this? It is circled in the picture...
