Hey guys, I have not been driving my RS much lately but last week it was warm and I took her out to keep things lubed up. No sign of oil drips anywhere, and oil level was still totally full. Well today I was looking under the car and saw a small oil drip about the size of a quarter. I looked up and I can see oil under the crank pulley and on the front of the oil pan just underneath the crank pulley. What type of leak is this??? Is this my front seal??? IF so, how much do these things cost to fix at a shop???
