Valve cover gasket reusable?

[theSHERPA]

I have a leaky Rocker Box gasket, and it appears I will need to remove the valve cover and gasket to get to it. The rocker box gasket is cheap--the valve cover gasket is not that cheap. Can I reuse the original, non-leaking valve cover gasket, or is it a one time use only gasket? Would rather only do this once, instead of going back a few weeks from now to do it again. Thanks.

Rubber gaskets that aren't very old can "sometimes" be re-used , cork type gaskets are a one shot. However I'm not a Cummins guy I don't know much about them, this is just my general knowledge/ some expierience. Most cases I would just replace the gasket so no worries in the near future. If nothing my post will give you a bumb back to top!
