can it be loose and quiet at the same time? ... were there any codes? what circumstances to think a loose chain?I brought it to our chevy dealership and confirmed timing chain is loose. the truck sounds quiet even with timing chain loose. I just don't want to spend money on items I don't need to buy. thank you
Well I must not have been clear I did do the filter 1st then the solenoid, and checked wiring my chain was way stretched and guides were practically non existent. With the new chains the rattle is gone. And the lack of power was right from the start at day one that I bought the truck I did notice more difference putting the new wheels and tires on but it did have the same drivablility concerns prior to that, I broke down and did the chains hoping that maybe I jumped time a little and that was the cause of the lack of power that’s why I came to this forum hoping to get insight on exactly how much power these have since it is my first one. My son has a canyon but with the 3.5l and it will run circles around my 2.8l????Oversized wheels/tires is basically like changing rear end gearing. If this started when you changed to taller tires, there's your problem. I have no idea why everyone here is so quick to diagnose their noises and performance issues on timing chain. What's the life expectancy of a timing chain? The life of the motor. Now, that may be the answer because most folks would just get rid of the vehicle if the timing chain needed to be replaced. There's probably a hundred posts here where someone thought that they needed a timing chain, but realized it was actually an idler pulley or water pump making noise. Also, there are at leas a hundred posts here where an upgraded oil filter cured the noise at start up. Look for an oil filter that has a anti drain valve. The timing chain tensioner uses oil pressure to create tension and take the slack out of the chain. Finally, change your oil regularly. Use the recommended viscosity. Thicker oil will not cure the problem! Thicker oil will not flow as well, especially on start up when it's cold and thick.
Timing chains stretch. That's why there's a tensioner. If you read the suggested steps to take for a P017 code, it mentions that the most common cause is wiring issues. Next, is sensors. Then the timing chain. Why does everyone jump immediately to timing chain?
