Help finding something to cover up oil drain!
 

I dont have the rubber cap that came on the nipple where you attach the oil return line. Anyone have any idea of a part number or something from mazda. Tried calling a dealr today and the guy was like. I dont know what you are talking about. I dotn see it on my diagram.

O'reillys had nothing that size. Only NAPA is pretty far from my house. I need it like tomorrow if possible. Please Any ideas
