What is this part?
It always comes loose after/while driving
Since it's in my car I figure it's some kinda important, but what is it?






Also any suggestion for a motor that burns all it's motor oil in about 3 weeks? My cars usually followed by a trail of blue smoke under decent acceleration. I google it, and some about mixing Alamite/CD2 with 40weight motor oil will help the problem.....any experience with this?

Thanks in advance
