When you say you replaced ALL hoses, did you replace the two silicone(green) hoses that are on the back side of the crossover? A leak in this area could be coming from loose hose clamps at those hoses, or leaking from the crossover. A leak at the crossover, is most likely to be located at the back side of the engine, under the egr valve area, where the crossover meets the block. Visual access is almost nil, unless you go down in that area with an inspection mirror and a light.
