Alright guys. I would really appreciate it if some one can explain to me what this elbow hose is for? the one going from the valve cover to the intake. It has a rip in it ( you cant see it from this angle) and when i plug it up with my finger my engine idles smoother.
And as you can see also it seems to be squeezed and crushed at the bend. So im pretty sure plugging it up wont solve the problem because its still crushed so the air will not run through it properly. Kinda like a vaccume that wont suck when you step on the tubing. I just dont know what this is called or what exactly is its purpose.
