Oil Dip Stick O ring change

Changed the oil in the 2001 Windstar today and noticed the oil dip stick moves around too easy. I noticed the O ring on it and changed it, if you have an O ring kit a #10 oring is what I used. Also noticed in less than a few months alot of trash already traped by cabin airfilter.Glad I have it.. I posted some pics up on the o ring change if you want to take a look. It now stays firmly in place. hope this helps, Gary
