Preheat the oven to 350 degrees F. Grease two 8-inch by 4-inch loaf pans.

In a large mixing bowl, cream together the oil, eggs, pumpkin, and sugar. Stir in the ¼ cup orange juice. In another bowl, sift together the flour, baking powder, soda, salt, cloves, 1 teaspoon cinnamon, and 1 teaspoon nutmeg. Combine with the pumpkin mixture and mix well. Fold in 1 cup of the nuts. Spoon the batter into the prepared pans. Sprinkle the remaining nuts on top.

Bake for 50 to 60 minutes or until a tester inserted near the center comes out clean. Cool in the pans for 10 minutes, then turn out onto wire racks to finish cooling.

Combine all the glaze ingredients. Drizzle over the bread while it is still warm (but not hot).
