I took on the task of changing the timing chain, guides, tensioner, and sprockets on a 4 cylinder 2.9L GM engine that comes equipped in GMC Canyon, Chevrolet Colorado, Hummer, Isuzu Ascender, and Chevrolet Envoy. It was no easy feat, but there wasn't really anything difficult about changing the timing chain. Really, the only problem was how the engine was engineered - it took an excessive amount of time to remove all the components in the way of accessing the timing chain.
Since Chevy or GMC products are not my bread and butter, I took to the internet to find a detailed guide on replacing the timing components. I didn't find much in my search except basic instructions, so I decided to write a detailed how to guide on changing the timing chain on your Chevy Colorado or GMC Canyon specifically, although the guide will work for other makes and models.

These engine that comes buried inside the F150 as well as the Taurus SHO has been seeing a little growing pains concerning the timing chain. I mean that statement very literally - the timing chains are stretching causing all sorts of problems. A stretching chain starts out to cause a few drivability issues, maybe a little bit of noise, then escalates into a full blown teardown due to bent valves. I love these 3.5L EcoBoost engines, but this is definitely an issue.

Of course, there were a number of other common problems, failures, and hiccups that are haunting the DPS6 PowerShift.
