Loose Timing Chain

I think my timing chain might be loose cuz my engine sounds like a couple of marbles bouncing around in a can. How can I adjust it cuz that sound is driving me nuts.

It's normal. It's the timing chain guide you have to remove. If it's already removed, you can buy a new timing chain kit $$$$$$$ but you can last a very long time with your "looose" sound. (your tensionners are used)

mine does it also.... 99.9% have the rattle lol
no one cares cuz it's normal.

The SR20DET has the same timing chain guide problem as the KA24DE?
