The seals will need to be replaced and you should be able to purchase them from a sporting goods store or online.

Crosman 766 wont hold air areadly oiled the seal

Try raising the pump lever and douse the inside with Barricade or Remington spray oil, then slowly pump it halfway or until you hear the air loss, do this several times or "rinse and repeat" until it keeps it's seal. Another good idea is to do this every couple months, leak or not!
