My car just died the other day while I was driving. It started back up after a few minutes but was hard to start. After 3 days it starts just fine but I turned it off because I am worried maybe I damaged something. There is no water in the oil what might be the problem

 

you may have hurt the head gacket you do not need to have water in the oil only if you hurt the head gasket on the compressure side not the oil or water chamber you lose compersser do compresser test first on all cyliner no greater than 25psi diffrent good luck
