The AOS per se will not leak externally, but the hose or the connections of the hose can leak oil. As JFP & Flmont suggest, find the location of the leak before you go chase solutions with parts.

You might need to crawl under and do some cleaning to find the exact location (once you've done the cardboard test to ball park the problem). If the leak has been occurring for a while, you may have a very dirty / grimy area. Spend $10 and buy 2 cans of Gunk engine clean and get the area cleaned up. This may cause a bigger oil drip as the oil will be less impeded by the dirt that's accumulated. But then you can pinpoint the area.

Caution: do NOT use high pressure as it can cause damage to fragile electronics. Garden hose with a regular attachment will be fine, just judiciously use it around small items.

+ 1 on the Gunk tip.

Afterwards, I like to use Simple Green (diluted with water), to get rid of the oily residue of the Gunk. And using Low water pressure it's important specially around the connectors

You will love the way your engine looks and you will be able to find the source of the oil leak, good luck!
