I think you should interchange it immediately, but if they are not replacing it then leave it. Tell the size or specification you want I can recommend you a place to buy good quality used engine at reasonable price. For your help, I am suggesting one site i.e.
http://allusedparts.com/engine.html that has large inventory and offers wide options to make a choice. However, no need to depend only on this, there are many more options out there as well. Just suggest what you are looking for.
