Thank you, I’ve been determined to at least try to make everything as clean as possible and as factory appearing as possible. I got a lot of grief over insisting on the aluminum heat shields on the factory LS3 crate engine exhaust manifolds but I absolutely love the look! Same thing with the plastic cover over the intake... 👍😎😎😎
The pcv was connected to the back of the intake. How did you plug the intake side off? And how will you put oil into the engine now there is something in the way of the oil fill neck hole?
On the early truck intakes like mine the vacuum port to the PCV is on top, I put a cap on it with a zip tie. When I need to add oil I just unscrew the line/adapter on the Passenger valve cover. It may look difficult but I promise it’s not to hard to get the adapter out. I admit it’ll take a wrench and a set of channel locks though. 😉
So you still have the hose from the passenger side valve cover nipple, going into your throttle body? Also, what did you do with the nipple on the top of the intake manifold that went to the rear pcv valve on rear of driver side vc
No sir, the hose barb on the valve cover and intake manifold are capped off. The vacuum nipple was removed from the throttle body and permanently plugged. The oil fill cap has a -10 AN fitting I use to connect 5/8” hose to the catch can ; same size setup as the driver side. JD
How does it affect idle? Does it affect the vacuum to the breaks? Thanks for breaking it down and showing us what you did. I’m fixing to tackle my turbo job and I’m trying to have all the ducks in a row and the knowledge you share helps a bunch! Thanks
@@bowtiebuilding Those outlets do not affect engine idle at all. The hose from the TB to the pass valve over sees the same thing whether it’s hooked up or not. I have my break vacuum line hooked up to the normal factory position. So far I haven’t had any issues running my power brakes. Good luck on your build! JD
Watch the video till the end whole time I watch the video I never once saw how to connect the valve covers to the CAT scan and they’re supposed to be a vacuum source?
Vented catch cans/breathers do not use manifold vacuum. The main benefit to running a vented system is to eliminate oil being sucked into the intake manifold. 5 yrs later I’ve never had any oil in my catch can, but it’s recommended to check/drain frequently. 5/8” hose run from each valve cover to the vented catch can; no vacuum source.
