Working on FWF with my new IO-360 from Vans. Just installed the sniffer valve. When I pulled the plug to insert the valve about a cup of oil drained out. Engine is long term storage from Lycoming. Trying to figure out why there would be oil. This was the only plug in the area shown in plans. I guess I don't understand the valve's purpose. I though this valve was to drain excess fuel so I don't understand the oil.
