No one remotely familiar with cars has any clue what this is. Someone at auto zone looked at it and no idea either.
Car runs fine. No leaks or any smells. Or sound.
Going to the Dealership for an oil change tomorrow after work. I'm sure they'll let me know. But hoping for you guys' invaluable input before then. I do hope I'm not driving a time bomb
Attaching some pictures. Hope it gives some clue.
