Guys, picked my car up about a month ago and recently started noticing a drop of oil on the garage floor and looks to be from the passenger side. I have not had a chance to get a good look underneath it yet and oil level is fine? I am not seeing any smoke in the engine bay but at some time getting the faint smell of oil after a drive. Any ideas? Did some quick searches and seems like cam plugs and valve cover gaskets the most common culprits. I was also thinking the oil cooler lines, but they run on the driver's side of the car, right? Thanks
