I see this.
Earlier in this thread there was a pic of what appeared to be -10? lines on the valve covers.
From what I can gather, GM ran a line from the air intake tube and a line from each valve cover to the dry sump tank. Is the Pro Vent on Gunner in line between the valve cover and tank or intake and tank?
......or is the Pro Vent the fresh air intake/blow off for the PCV system period. |
I ran 2 -8 line off the valve covers and tee them together to a -10 line. That line goes to the top of the Peterson dry sump tank. Then a hose (I think 3/4) comes off the top of the tank to the Pro Vent 100 (3931070793). Then a -10 line comes off the Pro Vent to the inlet tube behind the MAF sensor.
I have experimented with the other Pro Vent 100 part numbers and that is the one that has worked for me.
The Pro Vent has a drain with a one way check valve that drains back into the dry sump tank. (I need to look up the part number it is a Mann &Hummel part)
The dry sump tank has been modified to add 4 extra quarts. This is so the oil level is not as critical because you are checking it with a dip stick.
I know it is a expensive system. But it works great. I’ve done this on 3 cars so far and I really like it. Keep the engine bay oil free and keeps the engine happy.
Hope this helps
