ok, you are talking about the oil bypass post, has the spring on it. The black post that the oil filter goes over. Mine broke when I pushed too hard on it. Ok, Ok, I pushed it to see how springy it was and guess what, "snap", the little "button" broke leaving a fragment at the bottom of the oil filter housing.
Luckily I was doing an oil cooler replacement. I don't know if the functionality of the post and oil flow is compromised for you or not, but I usually tend to err on the side of caution. Replace it. They are about $55 bucks from the dealer. Sorry, don't have the part number. It is one screw on the aft side and a slight turn to take it out. You will need a long extention to get down into the oil filter housing. Good luck.
