I guess I did not check that. I dropped the
vb, and applied air to the rear square port on drivers most side and I get loud hissing, and if I look up in the park rod hole I see no movement. I pumped some smoke up into the park rod hole and quickly put shop air to the port and the smoke rushed back pit through the park rod hole, so I'm assuming it's lip seal. But my question is where is the bleed hole at? If its in the back, it could be just the bleed off pushing my smoke back out. If the bleed hole is the round one next to the square ports then I deff have a big leak.
