I need to remove the oil pan on my 86 Accord LX to clean the oil pump screen and associated parts. I have everything off that needs to come off including the nuts and bolts in the pan. On each side of the pan is a metal strip running almost the full length of the pan presumably to create a tighter seal. How do I remove these strips? I have all nuts and bolts out. Haynes or Chilton manuals do not show or mention these strips. Thank you very much. llc
