"dbcrue", yes, valve seats became hardened at that point in time. However, many engines today, including those in the Canyon, have aluminum cylinder heads. That in itself, would require valve seat inserts of some kind, as aluminum is way too soft to act as a valve seat.
In fact, my first car, a 1965 Chevy Corvair, had an aluminum engine, and valve seat inserts in the heads.

"cruznt2", are your tires wearing evenly across the tread? If not, then you should have the front end alignment performed on the truck, before throwing more tires at it. If they are wearing evenly, and simply wearing out, I suggest you buy better tires.
If it's any consolation, when I bought my '05 Canyon 4x4, it came with the 265/75/15 General Ameritech tires. Poorest excuse for a tire I've ever driven on. They were off the truck within a week (3-400 miles), and I say this in all honesty, I GAVE THEM AWAY!!

I have the 08 Chevy Colorado w/the 2.9L engine. Experiencing the same problems with engine knock during a cold start. Service managers and GM customer serv reps are all giving me the run around. What type of engine do you have in your new Canyon? I am also experiencing severe leaks inside the cab. Testing w/a hose on my own, I can tell the water is coming in from the back somewhere. GM and the service manager at Chevy tried to tell me the water was entering the car through a vent. Actually told me I have to keep my vent on recirculate when there is wet weather. What a joke! With all these issues occuring within the 1st year of ownership, GM wants to tear the truck apart, but not give me a new truck. Did you pursue the Lemon Law at all while dealing w/all of your issues? If anyone is having similiar issues, please let me know and contact GM or your service department, because it is definitely an issue.

If you mean a manual transmission 5 speed, I believe the answer is no. I went through all that a year ago when I was trying to get a manual transmission, and they have apparently become like photographic cameras - almost totally replaced with digitals, or in this case - automatic transmissions. Everyone tells me that no one orders those, so the factories have stopped making many of them. Well, you can get one, but only with the smaller engine, and I believe with not as many of the option packages. I ended up having to settle for the one they had in the showroom, which happened to be a 3.7 with an automatic. It had most of the options I wanted, and not many I didn't, so I settled. Shouldn't have to do that with the largest automaker, but this seems to be a society where customer service in all regards is not the priority anymore.

I retired from GM and worked at the Lansing Car Assembly which built at that time the Grand Am, Buick, and Olds versions. We ran 2 assembly lines with each line running 60 cars an hour on two shifts of at least 8 hours each. That is over 1900 cars per day. We would build about 2 cars per hour per line with manual trannies. Thats around 64 manuals out of 1900+ cars per day. We lost money on everyone of them due to the so few we built but had to keep them in the mix to conpete with the Toyota's and Honda's which those type of people tend to buy cheap models though most americans that buy domestic perfer automatics. Hope this helps you understand why GM don't make a manual in the 3.7. Those that buy the 4 banger buy it for only one thing, either they want the cheaper truck or want the most mpg's they can get.

"gfcar", regarding your water problems...There IS a ventilation system vent at both of the lower sides of the cab. They're visible between the cab and pick up box. Make sure that A) they're both in place; and B) the flaps are "closed" and/or not damaged.
