After changing my oil I was wiping down my engine cover area since it was dirty. Accidentally knocked this off. What is this? I picked it up and screwed it back on. Do I tighten it as tight as possible when screwing it back on or is it like the oil filter where I do the "3/4 turn"?
I bought my truck used a few years back and it didn't have a owners manual so I can not reference back, sorry
