oil is leaking into my car from somewhere up under the dash/cluster, and drips down onto the brake pedal and my shoe, and while it is not a huge leak, it is a messy pain in the ass, and i would love to figure out what is causing it, and fix it. i have tried looking up behind the dash, and it seems like pretty much everthing is coated in oil, and so it is hard to get a sense of where the leak is coming from. someone had suggested a faulty oil pressure gauge. how difficult of a repair job is this? do i need to take the dash out to solve this problem? or perhaps access through the instrument cluster? i am definatley inexperienced with doing these kind of repairs, so any help in the right direction would be usefull. thanks, -bones (79 240D manual)
