Does anyone know what the part number is for the pcv hose coming off of the valve cover that elbows in a 90° into the air intake? I had to put the factor intake back on mine and I noticed I am missing it so I just have the hose breathing into air. I taped the intake hole but would like to reassemble.
Ty!!

Thank you for quick reply. I have the hose. I need the little elbow that clips into the plastic intake that sits atop of the intake manifold.
If you go here just under the “A”

Well --- firstly --- it's NOT a PCV hose on the valve cover.
It's the KV Hose or the atmospheric side of the PCV system.​

That other hose is the CV side of the PCV System and it is 17/32" and that IS the correct hose on the driver-side by the master cylinder.

FWIW ALL KV or CV and Air Injection Reaction (AIR) hoses are measured in odd thirty-seconds of an inch.

17/32" qualifies.

That KV nipple on the vale cover is an INHALE ONLY fitting and it can inhale dirt directly into the engine. That's bad.

Okay I understand that which is why wanted to fix it and I need the little elbow that connects the hose to the plastic intake. The hose is exposed which I don’t like.

Which "a"? There's 13 by themselves and 3 in the word "ALAMY".
