How has the valve bent? It can only be because some other failure has caused it to bend and no, the engine would not run correctly with a damaged valve. If it were in that condition his mechanic should have done a compression test to verify something is seriously wrong with that cylinder and would have advised not to drive it if he knew his stuff.
Sounds like it has been driven with a defective water pump, which is a bad idea when it's driven from the cam belt, and the cam belt has failed, bending the valve. He bought it from you with a known (minor) fault and has made it worse by not rectifying it immediately.
How does the manifold relate to this? Is this a separate problem or is he claiming it has caused the bent valve or something?
But ultimately, the car was sold without a warrantly and he has been badly advised by his mechanic regarding the noise leading to further damage.
