The timing chain in my truck is noisy. I think the tensioner might need to be replaced.
The timing chain tensioners are known to go bad on these engines, and would cause the loud noises. The problem is that one chain is in the front of the motor, and the other is in the back of the motor. The engine needs to be removed to fix the rear tensioner. I recommend you have a mechanic like ones from YourMechanic come by to verify your need to have the tensioners replaced.
