If the filter is the Canton I have pictured Then I would replace it immediately!
This filter is in constant bypass mode as the end-caps are not sealed to the element housing. I went with this originally as I liked the no-bypass feature and the micron filtering rating, the filters lack of filtering killed my engine in less than 10 miles.
The signs of fail started upon opening the box as when I unbolted the cap the o ring was crushed when assembled- I contacted them and they sent me some extras to replace it but they too would not fit in the machined groove, fixed with swapping out to the smallest one and some careful assembly.
The next sign was the supplied -16 fitting I ordered from Canton almost touches the filter when screwed into the filter body.
