Oil pan warped
I've fixed .025 and .035 pans and covers. didnt spend the time to set them up in the mill. Just by hand with a big long block sander, 3x10 or 4x12, so you can keep it flat across a corner and get down the side rail, and not have it tip. Good norton/3m metal emery, wet/dry, with soaping water flow to keep the alum dust out. 60-80 cut thu it fast, finish with less, 120,220.. then scotch bright will look mint. It will get messy, and wet, heads up.
