I left out the option of doing it on purpose, conciously or unconciously, but you are right, it could be that as well. I think in the long run it will hurt you to actively refuse to help your colleagues, because they are smart, they will pick this up and be reluctant to work with you and share information with you as well. Not helping the people you work with has its advantages too, like more time and more focus for your own stuff, maybe even more carreer opportunities, but for me it is simply not an option anymore. I tried that, but it made me negative and miserable, so I gave it up. Now I try to be the engineer I personally would like to work with on a daily basis. If people get it, great, if not, it doesn't matter too much anyways. I do it for myself as well.
