replace just timing belt and heads, or whole engine?

My timing belt on my 2000 Kia Sephia went while I was driving it. I know they are suppose to have a non-interference engine, but I was told that there is probably at least some valve heads damaged since I was driving at maybe 50 mph when the belt went. I have yet to see this damage. My dad and I took the timing belt off a junkyard Kia today, it took a lot of effort/time, and now we are wondering since it will almost be more cost effective if we should just replace the whole engine (125k and possible damaged heads) with the other Kia's engine (only 75k). Considering we had to remove an engine mount today just to get to the timing belt and someone already took the tranny so we would not need to disconnect we are wondering if it would be better to just replace the whole engine. Is it just a matter of disconnecting the hoses/plugs? Considering the effort to replace the belt and possible heads I am wondering if the whole engine would be a better alternative? Anyone with opinions on this feel free to answer.

first of all. If it IS a non-interference engine - you have no damage. No matter what speed it was.
Why would you remove TB from different KIA? I do not get it...

What I think? Remove the head and see if you have any damage. I believe you do not. But, even if you do, it might be better (in terms of durability and reliability) to fix it by yourself.
When you fix the head, when YOU replace all the parts, you know what engine you have. If you, on the other hand, get an engine from junk yard, you have no idea how bad it is.


And on the end.
Why do not you just put a new TB and see if it works. Once again - if engine is non-interfere - it is non-interfere.

Thank you to kiaracer.


So, after reading the thread - I would simply put a new (brand new) timing belt and that's it.

Loosening crankshaft bold

Ok, so we have agreed that we will just replace the timing belt and see what happens. However I now need new advice. We canNOT get the crankshaft bolt loose. We have the car in gear with the parking brake on and me pretty much standing on the brakes and the wheels are still turning. We tried jamming it with a bolt however it start bending the brake, so we had to stop. We have a breaker bar and today my dad tried his electric impact wrench, and the SOB still did not give even a little. He is bringing the air tools tomorrow, but I am hoping someone knows of a trick or something we can do. I noticed some people mention replacing the timing belts themselves. Any advice for the most stubborn crankshaft bolt?

No need to take off the main crank bolt.
