I have a 3.1 liter engine that appears to be leaking oil from the block, somewhere under the throttle body. I lose about a quart a month. Where could this be coming from? It's not the valve cover gasket.

On 3.1's there is a, what is called a dummy shaft, it is closed up hole where a distributer would go if you where to put one on. And when the o ring in there goes bad, it will begin leaking oil, I have a 3.1 corisica with the same problem. Its quite a job just to get in there and change the o ring too, because I did it on another corsica that I had, but I refuse to do this one, not a good idea but hey
