I spoke with Bergman today. He said they started porting the inlet and outlet before they shipped them for this reason. The hose seats and the holes in the casting don’t quite line up,he said it can be fixed in the car. Take the hoses off and dry things out then look through the holes,should see the areas that need blended. My box is 2-1/2 years old,only got in the car this past spring. It’s nice when a person will answer your texts and calls.
