Hey B. Ya, I'm sure. It was on there when I put the dip stick in the tube, pulled it out 2 seconds later, & it was not. I didn't even blink. Felt like I was kicked in the gut. The top / handle of the dip stick was chipped / broken when I got the car, the plastic was very brittle. It was one of the first things I noticed when I first popped the hood. I thought, "just replace it, no big deal", then when I pulled it out and saw it had stopper / o-ring seal, I said "no worries, the oil is safe down there." urggg
