My 2012 4cyl with 54,000 km just started to leak a lot of oil from a sensor in the cylinder head above the alternator (front left side facing the engine). The vehicle is still under warranty, I was just wondering what this sensor is? I added a picture, you can see that there is oil on the alternator, exhaust manifold and running down the block. Regular drip with the engine running. Reminds me of a failed oil pressure switch from an old GM 305!
