Re: black coolant
Did it ever get hot? This is a new engine, right? That sure sucks if it is. If not from getting hot the problem is either from poor assembly or poor casting/materials of head. I'd do the plugs swap and see what you get, although I think we already know what that is. Still, no sense in breaking anything down before doing such a simple test. I've used system sealers before, but only on older engines. I'd want the issue corrected properly if I had a new expensive engine I hoped to get a zillion more miles out of.
