My 2015 Hyundai H1 2.4 Cvvt were driving, and it was making rattling sound from the engine. I wanted to tow it to a service center. But when i reversed it in my driveway one con rod went through the bottom oil pan, but it was still idling. i just parked it, and didn't start it again. i need to know if a Technician can give me quote to repair. i don't know must i do a complete overhaul?
