Wonder if anyone has any advice. Got a slow coolant leak. I have changed the water pump, expansion tank and EGR rescue kit and Still there. Could the valve itself be leaking? MANY Thanks

Ok still not sure what we're looking at with the black part the pic is too close up,
possibly the vacuum tank ?
i don't know exactly what you've changed in the way of seals but here's an exploded view with part numbers that may help you pin the leak down
