These castings have long been a source of trouble. Somewhere in the archives is a picture of an engine where the metal was eaten clean through by old coolant which leaked from the Y-pipe. The beauty of it is, you can have it weld repaired. I don't know how thick the castings are, but my opinion is that it's better to have someone weld-repair it and keep it clean in the future rather than try to seal it with diamond plate. My reasoning is, now matter how well you try to seal it, some moisture could get in there and just eat it away over the years. Some folks fill their castings with silicone which you could at least dig out and replace when it starts to get nasty. I was lucky. Mine were filled with enough topsoil, acorns and lost hardware to sprout a garden if only enough light got under there. I had no damage thank God. The castings came clean and were strong.
