diagnose this noise

nothing that i could see nyway everything seemed intact. there was nothing stuck in there either. i dont think its ps anyway it didnt seem to be coming from there

maybe big ends then man does sound like it could be big end rattle now that i listened to it again

i it was big end rattle it ould surely be there when the car is idling. its not there till i rev it up about 3000 rpm and im narly sure it goes aay when i get higher up the range but dont want to rev it higher now in case

ah it depends iv heard cars that sound fine on idle an wen ya rev they'll rattle

ive been checking the net most people have a noise like it and sat its vvt but a few are saying tits timing chain rattle whats this

no its not vvt man sure ur engine doesnt have it...id assume timin chain rattle is loose/stretched chain?

Had another listen, check your PS pump / fluid as said above...

i doubt its the AC pump if it has any?

only other thing i can think of is the big ends are wankd!

but i dont know much about SR20s tho..

there is hundreds videos on you tube wit the same noise im goin through forums now to check it out. very one saying its timing chain rattle but no on says whats causing it or how to fix it. some engines locked up in 6 months others are still running with it so i dunno

msg the nissan doctor an ask him to listen to the vid an see if anyone gona no its him

hate to be the bearer of bad news but the big ends are gone mate..
