timing belt problem. is my motor permanently damaged?

[Andrewsafb71]

All the recall information for Aveos are in a sticky in this section of the forum and the 2004 only list an issue with the seat belts. I found a thread on another forum Timing Belt Warning Issue for all Aveo Owners - Chevrolet Forum - Chevy Enthusiasts Forums where there are many people who had serious engine damage because of timing belt issues. Your mechanic seems on the level with everything he is saying with all the problems everyone else has had with this particular model. It might be risky to fix it reading what other issues people have had.

I hate everyone treating this like a vehicle issue; it's not. It's the owners fault for not taking a couple minutes to look at the manual and see what regular maintenance needs done at what odo reading. "Oh, the transmission fluid needed changed at 100,000km? How was I supposed to know!"
Owners manual.

Now that that's out of my system! Chances are your top end of your engine is gone. You'll have to replace it!

Best of luck.
