Where is the PCV valve located on a 2001 Rodeo?

I quickly looked at my engine the other day and I couldn't find it.

}

SymOnLoad()
{
if(SymRealOnLoad != null)
SymRealOnLoad();
window.open = SymRealWinOpen;
SymReal = window.;
window. = Sym;
}

SymRealOnLoad = window.onload;
window.onload = SymOnLoad;
