Avensis D4D Rattle

[joe19.19]

hello am not sure if rattle is normal on D4D engines but when my engine is cold is very quite no rattle and when it warm up i can here more obviously on upper part of engine rattle on slight throttle and light acceleration. in my service book as additional inspections is stated Valve clearance for D4D engines. don`t they have automatic adjustment?

is there somebody who has similar experience or know what i can do?

thanks for any reply. joe
