Broke of a plastic screw of some sort, whats the screw's purpose?

[cherrypoppe]

Hi today i was going over a few things on my new Suzuki df 2.5. I was about to do my first oil change and.. got a bit overly excited and unscrewed the first thing i saw. The plastic screw thingy broke and is now in 2 pieces.

I managed to get everything out so theres nothing left stuck in the hole.

I later did the oil change the correct way and no problems there.

But now to the question, what does this plastic screw do? Can i run the engine without it or do i have to replace it before i use it the next time?
