How often should you replace a timing chain?

I’ think I’ve only replaced just the chain once on a stock engine because it had over 300k and the timing was all over the place. But other then that, only if I was in that deep fixing something else on a high mile motor and then it just makes sense to do it.

Can a GMC Canyon timing chain be replaced?

The scoring on the cams is common but too much scoring is bad and theres actually a TSB or PI (can’t remember) that talks about replacing the cams and valve cover with an updated cover and PCV to not allow moisture into the head. Oh and I doubt the chain has stretched enough to reach the limitations of the tensioner, its pretty long.

Are there any issues with LS Motors timing chain?

The only issues I have ever seen on the ls motors timing components are a result of huge cams. The ls3 style tensioner system can break with big thumping cams and the ls1 style cam sprocket bolts have been known to back out. Stock stuff seems to hold up great.
