Help! What does this VAC line do? PCV Mod
Could you please identify what the ?? line does. EDIT: -Solved thanks
Would it be ok to run both of these lines to the same vacume sorce? Possibly the PCV on the throttle body? I know the line to the throttle body doesnt have much vaccume, and the one to the manafold has tons of vaccume. Would it be ok to send them to the throttle body PCV even though it is a low vac source?
Thanks for the help!!
so i run both lines to a Y block, and then through a filter, i plugged the TB line
I want to make sure to trap all oil in the filter

The ?? you put in the picture is the PCV line. The other line you marked "PCV" goes to the valve cover, so that's not PCV...
Here is my write up for the PCV mode, mode this helps:

do you think that line on the TB will suck oil too?
Initially i routed both lines to a Y block (pcv, and the tb line) then to the filter, and then to the intake. This did not work well. If you were going to filter both lines you would need seperate filters, one for each.
I removed the Y block, and ran the TB line the way it came stock, and then routed just the PCV through the filter.
Questions:
-Do you get a whistle when your car is cold? I do. - EDIT: Fixed
-Why does the arrow on the filter face twords the engine, i would think the flow would go to the intake. EDIT: the arrow should go twords the intake

The line from throttle body comes form the valve body, I don't know if that sends oil vapor into throttle body or not. But I don't think so... :confused:
No whistle but I get too much other noise to hear anything clearly.
You know what, you are right. I meant the flow to intake and the freak arrow is right on the line from PCV, :bb Need to fix that soon.
