That's good to know don, thanks for the Honda part number.

My case has iffy threads, I made my own bolt, longer but with same 13 mm wrench size head to engage more case thread. It's been working ok. I've tried plastic gasket and copper. Both worked with the new bolt. Added a bit of anaerobic sealant ( locktite number slipped my mind) each time.

 Again thanks for the Honda part.
