It leaks oil soon after i start the car and runs dowm the front of the motor on the right side.Its hard to get to, it us under the fuel lines that come in under this black plate that the throttle lines and the fuel lines are above.It looks like a distributor goes there like it was plugged up.

You are correct, That hole is where the distributor used to be in that engine block. The ignition system in your 1995 Buick Century does not use a distributor. What is in the hole however is not a plug, it is a gear driven shaft that drives the oil pump just as the distributor shaft used to do. There is an o-ring at the top - just like a distributor o-ring. The o-ring is probably hard as a rock and not sealing any more. The oil pump drive will need to be removed and the o-ring replaced. Even with everything out of the way it can be a bit difficult to remove the oil pump drive.

jim thanks for you help so much,it makes sense now because of the ignition system .But it seems to me they could have used a better way to seal this,because i have heard so many problems people have had with this.Thanks Randy
You are correct about using a better seal - some folks use a flat paper distributor gasket in addition to replacing the o-ring seal - no more leaks, ever!
