timing belt cover seal. replace?

how important is the rubber seal behind the upper timing belt cover? mine is a little dried out, but not in terrible shape. usually, i would replace things like this, but it’s $25 from local dealer. is it worth the cost for a new one? also, should i use hondabond on the seal? thanks.

I wouldn’t bother…if you’re worried just honda bond it.

I’m not even running any covers at all…
