My son was driving down the road at 35 miles and hour and the engine dropped out of the car. Upon inspection of the car afterwards, it appears that the rubber bushings on four bolts for the engine mounts had disintegrated / dry rotted and the bolts that were holding the engine into car were severly rusted which resulted in letting the engine drop out of the car. The car had just passed inspection. There was no rust on the body of the car and only slight surface rust on very little of the cars undercarrage.
