My mechanic wants to charge me $500 to clean my egr valve because he says it is located in a bad labor intensive space and I think that is too much.

Are you sure it's the EGR valve? The EGR valve is located toward the top of the engine, i think to the right (as facing car) of the intake manifold. I replaced one on my 1988 Ninety-eight (basically same engine). The part is pretty expensive. I have heard (but haven't done it), that you can put a little antiseize on it to keep it from sticking. Replacing it isn't much work. Make sure you replace the gasket with it.
