Revitalising old pages in a blog - is it worth it?

    This is a question about a blogspot blog, not a hub.

    I have a blog with about 250 posts spread over three years. I'd like to add some content to it that would improve some of the earlier topics. But I don't want to post it as new topics, because it's not what I'm talking about now.
    If I add it to some of the older pages, by editing, possibly also editing the page titles, will it ever be discovered by search engines, or is it just wasting time?
    In other words, do the search engines revisit old blog pages in search of changes?
