I have been working on taking off the EGR valves for 4 hours long and still can't take it off.

If you have a P0401 code from a CEL, the first thing is to check the EGR vacuum modulator. It is a little well usually next to the EGR. Pop the cap off and dust the little sponge inside. Sometimes this gets stuffed up with carbon particles and causes recirculation problems. You should clean the tubes hooked to it while you are there. Reset the code and see if the light comes back.
Replacing the EGR is not a tidy job. It is an expensive part to replace and you will disconnect the three hoses and dismantle it from engine by two nuts. Save it for the later if the previous trick fails to work.

REPLACE the EGR valve and gasket, stop being cheap. sometimes there are things that cant be fixed. It could have a micro crack in it or a bad spring. Just brake down and replace it. I have been there so many times. You smack your head into the wall for hours on something that you dance around for months. Let me know once you replace it.

There is a VSV (vacuum switching valve) , usually mounted on the back side of engine block, under the intake manifold, as well as the map sensor, that can also cause that code if one or the other is faulty. It takes some pretty detailed troubleshooting to confirm this in some cases, so if that's not in your line of work, you may have to have it properly diagnosed, or take a 50/50 shot at which one first.
