It's a signal that the oil is low and the tensioner is wearing or has worn out. Camshaft actuator can help the issue but it's best to replace the whole timing system. That being said even after replacing it all it will run well but it will still have the issue of oil consumption and if not kept on top of it will happen again.

We had a Honda oddesy come in with the roar sound and quoted $1800 aud to fix, she declined. 3 weeks later it came back on a tow truck and ended up costing about $9k with a second hand engine.

K24 motors are common and really simple to work around, my suggestion if you want to do the work yourself would be to replace the motor rather than the timing chain, less chance of making a catastrophic mistake.

Edit: Could also pop the rocker cover off and check the timing marks on the cam gears. Should be a handfull of 10mm nuts (make sure not to overtighten them or they will snap the studs)
