This side plate, which covers the access to the water jacket side of the cylinders, was completely clogged with rust and other junk. I cleaned out the inside of it. When I cleaned the engine side of it, much of the metal had turned to rust. As you can see by the photo, one of the holes is quite a bit larger now, due to the corrosion.

My question is: Is this part beyond use? What are the consequences of the enlarged hole? Anyone got a spare lying around they'd like to part with for a reasonable price?
