Valve cover gasket replacement

Hi guys, question. If I'm to replace the gasket, do I need to replace the spark plugs that the oil leaked to too? Or can I just wipe it down and reuse it? I'm asking cause I just replaced my plugs last month, it's still new.

Do yourself a favor and replace the whole valve cover. It comes with a gasket. 90% of people need a new valve cover.

It will crack over time and the PCV system is built into it so it gets clogged over time.

Thx. I'll have mine checked when they do the gasket.

If the oil is on the threads of the plug, just wipe it off and reuse them. If it's gotten down to the electrode then they'll likely be okay but you might as well just replace them. They're cheap enough that you might as well do it while you're already in there.
