Complex one but here goes. A mate of my mate had a crash which buggered the rad and a fair few other bits. He drove the car home with no water and the engine is now properly fucked. He unfortunately told his insurance company that he drove the car home and they won't pay for the damage to the engine as it's not directly caused by the accident.

He now needs to source a replacement V5 engine but doesn't know where to start looking.

Seeing as PF is a wealth of knowledge I thought I would ask here first

Or does anybody think he may get away with having the current motor stripped and rebuilt?

Car is a 52 plate Golf BTW
