I HAD A POST BEFORE THAT WENT AWAY AND I CAN SEE IT ANYMORE ANYWAYS sorry caps , i replaced the pcv valve on my valve cover and it is still making a hissing/rattle noise so im going to change the gasket and i that dont work what else can it be?

it could be any pipe/tube that carries a vacuum...I don´t see how a headgasket can make a hissing sound?? it´s not pressurized.

thats just what im going with what someone told me before maybe ill try the vacume tube for the pcv valve first

That definately sounds like a vac line. Either one of them came loose, or one is damaged. Good luck!! :-D
