I can't really tell where the hissing comes from to be perfectly frank. It's ear piercing and I can't bear to have it on for long.

I don't know where else it could be coming from other than he intake manifold, all I did was replace valve cover, crank case vent hose, and intake manifold. Could crank case vent hose issue cause this?

I really appreciate your help.
