rattling somewhere in the engine????? need HELP

hey guys, kinda worried right now, about 30 mins ago, i was driving normally on the fwy when i heard a rattle 0.o when i got home, i looked around but i cudnt find the problem. i check the belt tensioner and that was fine. any where else this cud be???

when at idle, it doesnt rattle but when i press the gas pedal, i cud hear a loud rattle noise on the righ side of the engine. i was thinkin of a loose bolt but cudnt see it anywhere

any ideas? please help @.@ pm me if possible thanks guys!

Bad engine mount? Do you see any leaks at the mount on the right side?

I knew one of these days listening to Car Talk would pay off. It just may have taken time for the vibrations to get bad enough to cause the rattling.

i had a rattle under load from the right side, sounded almost like a rod knock or piston slap. turned out to be the stock crank pulley. when i replaced with a WMS 2% solid pulley, the noise went away. i do remember there being a problem with the stock pulley making noises although i do not remember the details. hope this helps.
