Ok my audi a3 (cough cough 1.6 8v) has done the piston rings! . I have popped the head off myself and the rest of the block out Sunday to be sent off to be reconditioned. I am paying £470 for the engine rebuild including the head and guides done and the piston rings changed! Then i just need to get the usual stuff such as waterpump, thermostat, cambelt. Just wondering because to me this seems like a really good price looking for opinions?
