Looks good! The oil filter was an "optional add on" LOL!! Ya I have seen them on equipment stuck in some odd places!
I used to paint the engines when I rebuilt them. Machine shop hot tanked the parts, so without paint they rusted the first day out!
Oil pans don't last long under there without some paint on them.
