The tube is not loose at all, I assume it's all the way in.
I'd have to crawl under and see but I believe the dipstick is pretty high up
vs the low hanging parts of the pan that got hit by road debris prompting the replacement. Anything is possible but off the cuff it looks unlikely. I'll
look at it further this afternoon.

Could one reasonably assume there would be some self-leveling over many thousands of miles if the oil was actually over-filled by a quart or more, and/or that there would be some sign of leaking, frothing, etc, eh?
Never has been, weeps a little from somewhere down low and front but not enough to drip very often, I assume the timing cover or some such. The dealer put a head gasket on it not too many years ago, seems dry up top.
