Rocks/Pebbles in my engine? Options

[dabazied]

Hey peoples...... Pretty much my question is what do you guys think this could be? It sounds like rocks/pebbles are clanking around in my engine. When I rev the engine it gets louder and as the rpms go down it slows/quiets(the rock like noise). Would this be a fuel filter issue? The celi has been sitting for a while now and the gas is kinda old but i'm gonna drain that out soon before actually driving it. Let me know what you guys and ladies think. Thanks ahead of time

as for the sand and pebbles noise that goes away when putting in clutch from my own experience its ur throw out bearing .... sounds like something is being grinded in a way had same thing happen me. dont buy cheap ones and spend the money and get a whole new clutch kit from toyota dealer.... and as far as ur problem with when hitting brakes it takes power away from engine and puts strain on ur electrical system then look into checking for vac. leak or check ur alternator and battery along with connections to both as ur sparkplugs and wires get there juice from alternator and battery which when ur idle drops low ur battery voltage also drops and when u hitt brakes it draws power from everything so if ur engine is not in to good of shape then it will make it self work harder.. exaple as when u turn on ur air conditioning it takes power away from engine..... hope this all helps you !!
