When you added the breather to the passenger side valve cover, did you leave the port on the throttle body open or did you plug it with a hose?

I don't have a throttle body port on my 2009.

Before you added the breather to your valve cover what was connected to it?

Intake tube

I guess the 5.3 in my truck is a little different that yours. I am going to try keeping the passenger side stock and add a vented catch can on the drivers side and see how that works.

NNBS throttle bodies don't have a vacuum port or a place to connect for coolant flow.

When I did my NNBS intake conversion on mine, I took my passenger side valve cover port and ran it to a capped off port on the passenger side of the intake, on top.

~60k I think. Only regret was not getting it sooner. I went in baby steps when I shoulda went right to 10 psi.

I know this is an old thread, buts it's going to be very useful when I get my kit.
Thank you!

Do you have a part number for your Tru cool?

Tru cool max 4739. For vehicles 40,000 GVW. I took off my stock 2500hd cooler and put this one on and changed the lines over to An-6 fittings.
