oil leek on start up

hi all
i just bought this car, it is a 1995 eclipes, and i noticed a oil leak, only when i start it and it looks to be coming from around the oil sending unit but not sure and there is a allen head bolt in a hole about an inch from it. it sure uses oil and it looks to be leeking in the oil sending unit area, anyone had this problem before, thank you all for any help

you should have probably posted this in the other eclipse forum. this forum is for the 3G eclipse. you have a 2G eclipse. you could probably find more help in the other forum.
