Onan 4000 KY valve cover gasket reusable?

Took it apart this afternoon. Valve cover was stuck on..took some tapping to break it free. Gasket broke in half-half to valve cover, half to cylinder head. Was hard and crunchy but not too difficult to clean up.

I'll add to the opinion it is not likely to be reusable and not to count on it.


One thing kind of cool is bolt torque sequence appears to be cast into the valve cover. Numbers near all the bolt holes in sequence.
