Vacuum line

[Viper83101]

So when I done my intake manifold removal, I noticed that there was a small rubber vacuum line that connects to the bottom of my stock throttle body. I couldn't tell where it went and I have no clue what its purpose would be so could someone help me out with info on that vacuum line?

It's the crank case vent, it goes to the nipple on one of the valve covers. The other valve cover has a line that goes to the CAI plumbing someplace. Where depends on factory or after market.

Well since I have a catch can Installed, it is a line that I can disconnect from the throttle body and cap off? Im just trying to completely keep any of the blowby oil and gases from being sucked back through the engine.

The one on the throttle body goes to evap system. The bigger one on the manifold just pasted the throttle body is for the valve cover and if you have the catch can you can cap that one off

Yea I have the one capped off at the intake manifold and the lines coming off of the valve covers going straight to the catch can. I just didnt know exactly what that line to the throttle body was for and if it was pertinent to cap it off for any reason.

I ran both vent lines from the rocker covers to a catch can and capped the nipple at the bottom of the manifold that is just behind the TB.

Are you sure the nipple is on the TB and not just aft of it ?
