on my 600 there are 3 socket caps under the cover that have to come out before the valves do...take a closer look ...steve

The link below should give you a better idea at what you should have in the 500. I think that you should be able to wiggle them in and out to get some of the encrusted oil off of them so that you can pull them out. Other people here on this site have suggested to spray a little carb cleaner on them and let it sit for a half an hour. Then try pushing them in and out again until you can pull them all the way out. Good luck.
