SEE LAST PHOTO, IT'S AN UPDATE GALLERY.

I don't know a damn thing about the inner working of an oil filter. I make these comments from my examination of the used filters that I cut open
with a Milwaukee Sawzall. This is offered for your amusement only, and not to suggest you believe my comments as those from a person enlightened
in oil filter manufacture. Click open each photo for detailed comments.
