My Audi A5 was leaking oil but was running and driving fine! While driving a warning came on saying oil pressure too low. I parked it, turned it off and went into the store to buy oil. When i came back out it would not start up! Got it towed to a shop and they said i have bent valves and that i should be looking for a new motor?! are bent valves repairable or do i dish out for a new motor? Thanks
