can damage be caused by overfilling oil?
This more of a follow up question about the same ford escort with the damaged #4 sparkplug. I decided not to make repair on this car (too expensive) due to its value. I had loaned this car to my daughter while hers is being repaired. One thing I neglected to do was check the oil level before tearing down a bit. Well, I finally checked and found that it is way overfilled. The oil is about one and a half times over the full mark! So I am assuming that it has over 10 quarts of oil in it. I know she was on the highway when troubles began and was at idle when the engine suddenly stopped. Could this have caused the engine damage? Iam guessing yes but don't really know.
