Ford Windsor small-block timing covers can vary depending upon standard or reverse rotation design, with or without mechanical fuel pump opening, and more. Know what timing cover you have and always use the right gasket for it. Most water pumps now use a universal back plate with a simple round hole, but you still need to get the “tombstone” opening on the timing cover right. Also watch for the inboard bolt holes that open to the timing cover valleys, as they can leak coolant with the wrong gasket used. We’ve seen people install threaded plugs with sealer on timing covers that don’t require the use of these holes (arrows).
