I would think it might be squashed a little if you didnt have it seated all the way. Or it just might have seated when you tightened down the cap.

Yup, same thing happened to me. It didnt go in all the way the first time but i was able to move it in more after a better push. Yes i did pull it back out and it didnt look damaged to me. I used an oil filter wrench to tighten the cap. (BTW I'm using the same Mann filter I believe you used). Thanks Mike. I'm thinking it must've seated properly then. Makes me feel better.
