The problem is _what_ is blown. Throwing a rod can be relatively minor, or it could be 'blow a chunk out of the engine'. A worn piston rod can break, or it can wallow out on the cam, etc.
If you want to spend the time on it, you _could_ pull the engine out, put it on a stand, and take it to bits just to see what happened. I have a 07 vibe with 215k or so on the engine that's still in good shape, that I need to sell.
