Hello we are trying to sell our Kia Optima LX the engine went bad in it and it has a slight engine knock mechanic tried fixing the engine by replacing the crank rod bearings but once he took the engine apart we realized the engine was beyond simple rod bearing repair because the crank was all damaged by the bearing that spun around. So here is the deal car was put together with new rod bearings so it could still run and drive somewhat it still has a knock in one cylinder where the spun bearing did the most damage. **We got a different second complete engine** for it so a mechanic could replace it but never got to actually installing it. So here we are car is** for sale with a second engine that needs to be put in** over all the car is in decent shape has dents and scratches it has completely new tires and a new battery. We need a new car so this has to go .If you have any questions please feel free to call or text me at (814)441-2056 ... Selling as is Car will have to be towed...
