Good afternoon,
Can you upload a picture of the leak?
The only sensor above the starter is the crankshaft position sensor.

That should not leak oil but it does go into the block.

thanks for the very informative response. i can't get under the vehicle anymore as i am handicapped but i do remember oil leaking in this area. maybe it came from my rear seal or head gaskets. I will have to get someone to check it out more thoroughly. if it's not something that leaks i may have misjudged where it was coming from.i appreciate your time and thanks 2CarPros!
