Okay to start off I picked up a 2011 S4 from auction that rear ended a pickup. The radiator clearly showed the imprint of a ball and hitch from a pickup on the passenger side of the car. It hit hard enough that it broke the motor mount on the passenger side along with some other parts.

Fast forward to once I was able to get the car running and driving. Sitting in the driveway warmed up I would not get an oil leak, but if I took it for a drive, it would be leaking oil with a consistent drip, which was coming from the front of the motor. I replaced the valve cover gaskets, the front main seal, and the oil dipstick o-ring, thinking this was the majority of places where it might leak in the front of the motor. When all those fixes didn’t work I finally added some UV dye to locate where the leak was coming from. I was able to find that the oil was pooling up in the valley under the supercharger by the pcv valve and flowing down the front of the motor. I had replaced the pcv valve already, so put in a new oil filter housing gasket and changed the purge valve the plugs into the top of the pcv valve. After all these parts have been replaced I still have the same leak happening. Is it a possible head gasket? If so how in depth of a repair is it?
