I took my recently purchased 94 Concours with 111k miles to get the first oil change the other day. I knew it leaked oil, a few drops on the drive each overnight park and I can just smell it when getting out of the car, but there is no smoke wafting out anywhere.
So I pull into the local quick change place and when the guy goes into the pitt I hear "Gawd Awmighty!" It was a little wet down there. The owner goes below and comes back up to talk to me, but I can't remember all that he said. He said it was leaking around a oil sensor of some sort in the bottom of the oil pan. "Just screw it out and screw a new one in" he said. He also said it was leaking around the oil pan gasket. He said it could be removed easily.
1. What sensor is on the bottom of the pan and how do you change it?
2. I'm pretty sure I've read on here where the exhaust cross over is in the way and prevents you from removing the pan without moving the motor.
I don't mind a little leak, it's an older car and I didn't pay much for it, but it's very clean and nice looking and it's leaking a little more than I would like.

Re: 94 Concours leaking oil question
Not sure if your engine has an oil level sensor but it does have an oil pressure sensor. Both are subject to leaking around the metal body/plastic connector crimp joint. Not uncommon. Did they tell you which one is leaking ?? Both are right on the front of the engine: the level sensor sticks out the front passenger side of the pan, the pressure sensor sticks out the side of the oil filter adapter head. With the car up in the air either one takes 5 minutes to replace.
