    That's not necessarily true. The 2.5 is a great engine but it had faulty head gaskets. If you rebuild the 2.5 engine (what do you mean "blown"? If it's just the head gaskets, that is certainly fixable) or even just replace the bad head gaskets with the improved type, you should be fine. My '97 2.5 engine gave up the head gaskets at 130,000, hardly a "time bomb", and now with new gaskets it's running great.

    The 2.2 is a good engine but has less power and torque and you may not like what you get in performance, to say nothing of the risk of installing a used engine. If you were planning on installing a rebuilt 2.2, you'd be better off installing a rebuilt 2.5 with the newer type head gaskets, IMO.

    Aside from head gaskets, the only thing you must do with a 2.5 (and to some extent a 2.2) is watch the oil level. These engines will consume a small amount of oil, and if you don't check the stick periodically, you could run low on oil.
