You should check the cam deviations. Depending on driving style you may be close to the spec limit which is +/- 6 degrees for each bank. Anything over 8 needs to be addressed asap. You can only reliably check the deviations after the engine is fully warmed up. I don’t subscribe much to using cam angle variation to assessing IMS health.
You should ask when the AOS, drive belt, spark plugs, coil packs, and water pump/thermostat were all replaced. There are updated coil packs. All the other parts are due for replacement or should be suspect.

This reply is more so to verify what i've heard or be corrected, though when it comes to a rattle, ive heard only 2 of the tensioners have a chance of causing the rattle while one is very unlikely too. As well as if the rattling continues it's possible the chain guides themselves could be shot
