I have a long drive so I often check all fluids, last Thrusday before leaving I saw the the oil level was at the halfway mark. Added oil and drove to work which is 1 1/2 hour trip. After getting back home I started looking for leaks and could not find any, in addition there is no oil on the garage floor. After it cooled down, removed the radiator cap which is were all the oil is. Drain the oil and checked and it was extremely clean not radiator fluid, etc. Took the car to the closest Kia dealer on Thursday and was told I will not have the car back for possibly 3 weeks while they fly in new engine. Asked today what they found and the Service Manager said he did not know but was told to replace the engine. Of course I can only get a loaner if I take my Kia and tow it 3 hours to the original dealer I purchased from. So it looks like I get to pay 38.95 a day for the next two weeks till the replace the engine.
