ENGINE KNOCK

1998 Dodge Dakota

Noises problem
1998 Dodge Dakota 6 cyl Four Wheel Drive Automatic 56000 miles

So I have a low knock that kicks in when I start up the truck. It is pretty low in the level of the knock, but it is also a low tone " soft" knock (for lack of better words).

It is real subtle. So that point being made, after about five seconds the knock kinda fades out and only when I hit the gas does it come back a little.

Is it because the knock sensor kicks in that it goes away?

And if that is the case, either way, is it possible there is an issue with the timing chain causing the knock, or internal issues?

I will assume the noise comes from the engine. If it is worst in the AM, chances are it is either a main or rod bearing. However, that is odd with that low of mileage. As far as the knock sensor, it is responsible for ignition timing to prevent valve ping.
