I'm not sure what you mean. You made a custom 404 redirect? What is that? A custom 404 page will not stop errors from showing up in Webmaster Tools because it still is a 404 page. That is, file not found. Your website should never have 404 errors, custom or otherwise. Just 301 redirect every error page that Google is giving you to good pages.
