I own a 1999 Lexus ES-300 automobile that was purchased used in 2002. The engine stopped running as I was driving home from the atlanta airport and would not restart. Just prior to stopping the car began making a rattling noise and then simply stopped while I was driving it. Upon inspection of the engine by Lexus mechanics I was informed that there was "oil gel" in the engine and that a new engine would be required.

Engine check light came on more than eight times in the last eight months. Dealer examined the vehicle twice, but could not find the cause of the problem.
