I had a malfunctioning timing chain and its parts, and an engine problem on my Toyota Corolla 2005 without prior warring, such as an engine check light, rattling, knocking, or stalling. Also I wasn’t aware that these problems could happen because there isn’t any timing chain system maintenance in the Toyota 2005 scheduled maintenance guide booklet. The independent mechanic who repaired my car thought that the tensioner on the timing chain may have had a problem that caused the cam gear to wear out, so that the timing chain slipped off the cam gear. Then, the problem caused the engine valves to be bent. Finally my car got fixed. The problem occurred in a shopping mall parking lot when I started the engine, I felt boom, boom, knocking coming from the front of the car. I drove out of the parking lot carefully, but I was concerned because it was the first time I ever had this knocking from the car. So I stopped in a different parking lot of the same mall. I looked under the hood and checked the drive belt, which was intact. There was no foul smell. I restarted the car and paid attention to anything unusual. I heard rattling and I decided to take my car to an auto mechanic shop, which is closer than going home. With my emergency light on, I drove into the street less ¼ mile when I heard sounds like metal or soda cans crushing around in the engine. Then my car slowly stopped and the engine stopped. I put the car in neutral and slid down to the side of the road, barely off the road. Eventually my car was towed to the auto shop. I have a worn out cam gear, a tensioner with a few fine cracks, bent valves and the timing chain. I called Toyota customer service on July 24, 2015. But I was told that since the car warranty of 60,000 miles had passed and I didn’t take my car to a Toyota authorized auto shop they won’t deal with my car problem.
