valve clacking sound

[joes300]

I own a 93 es300 and after it warms up there's this loud noise that sounds sorta like a valve clacking but i'm not entirely sure. Has anyone had this problem or know how to fix it? Please let me know I'm hoping it's not a bent rod or anything like that

unlike some cars with self adjusting lash

(space created over time of the cam and valve our valves have to be shimmed to stop that noise

but normally it gets quieter rather than louder when warm

:D i had the same noise and it turned out to be the honeycomb inside of the cat......funny tho, i still pass emissions with flying colors!

were exactly is the sound coming from?the top of the motor or bottom.like sk said if it was the valve it would get quieter when the engine warms up not louder.a rod would be noisy hot or cold.check and try to see were the noise is coming from better then repost.hope you find it!
