Do you think that there is any point in just replacing the timing belt or would the damage above mean that the pistons etc have been ruined beyond repair?

Thanks

The pistons are unlikely to be damaged unless you were at very high RPM. Its the valves that will be bent. Replacing the belt will be a waste of time as you can tell from your video that there is no compression so all or most of the valves are bent. Head rebuild required unfortunately.

Might give you an idea of what your getting into if your still going to try this yourself....its the same engine, although from the newer model nubira.
