Anything that touches oil either is cleaned or recycled if you cant guarantee its cleaned. I've totally disassembled oil pumps and other parts like that and meticulously cleaned them to save $ but parts like oil coolers are disposable. You can never guarantee that they are free of debris.
Its possible that you could totally replace the entire engine - air cleaner to oil pan - and not replace the oil cooler and you would be better off stabbing yourself with a fork. That crap will haunt you or the next unsuspecting owner later. Braided stainless steel turbo oil lines come to mind, throw them in the trash. Another great example of what you can't see you have to assume is dirty.
