started up the mower today for the first time to do battle with the yard, and my lawn mower started spitting out oil. Took it all apart, clean it up, cleaned it up, and started it again for 30 sec. Oil seems to be leaking from where my finger is pointing in the pic, and when I turn the engine over by hand this black piece pops up and down. Is this a PVC and needs to move, or is it just an oil pick up that is loose? It's a Tecumseh engine LV195XA on a 07' toro. Any ideas out there? Thanks
