Well, you can't have a "bent piston". They must be referring to the connecting rod if something is bent. Or did they say "bent push rod"?
Either way, here's the deal. If you cracked a piston or bent a connecting rod, not only will you need to replace that, they'll need to have a machine shop check the cylinder wall for marring or gouging. If there is any issue with the cylinder wall, they'll have to bore it out and sleeve it to fit the piston back it. Since I don't believe that there is larger pistons out there for this motor, you wouldn't be able to bore the entire motor to make a larger displacement motor.
After they do that, the will also have to rebalance the crank, if not replace it as that will be fudged up from a bent connecting rod. Then the main bearings will need to be replaced as well. It might just be cheaper to replace your current motor with a crate motor.
Now if it's a bent "push rod", as long as the head looks ok where the rod goes through, you might be able to get away with just replacing that rod and calling it a day. That would be A LOT cheaper.
Sorry, got carried away there. If the engine needs to be replaced or worked on, the insurance company shouldn't total it as long as the cost is no more that 70%ish of the total value of the car. Now, that percentage varies depending on insurance company, so you'll need to see what your company totals out at.
