are u sure is the timing chain?

because cult it by the timing sensor or the timing auctueror sprocket

There is no timing belt on a trailblazer only a single timing chain. After some research I found out that the timing chain is still in service in vehicles that have over 150,000 miles without issues. It does not appear to be a weak link in this very strong Atlas LL8 design.

The posted labor to change it out is listed at 16 hours. Not really a driveway job but based on history not a problem on these trucks.
