5.3L swap into a 64 chevelle.

I have a PCV valve in the back of the drivers side valve cover and what looks like an open vent line on the front of the pass side valve cover.

Does it matter where I run these hoses to on the intake? I am thinking any vacuum source is acceptable but and not 100% sure.

Someone respond if I am overlooking the best or correct location to run these crankcase ventilation hoses.

Take a look here. You may find several options....

That link takes me to a "Sorry no matches" search request?

The more I read the more confused I get.

I think I was sold an intake from a cable type throttle body that had the DBW throttle body placed on it. 2003 5.3l engine.

I do not have a location to run the tube from the pass side valve cover to the DBW throttle body as I see the LS1 does. The spot right behind the throttle body where I see some of the trucks go to is a metal plug that looks like it was there from the factory.

I look at some diagrams and it shows air going into this location. How could air go in to this tube on the pass valve cover if it is hooked to the throttle body? Wouldn't it have to draw vacuum if hooked to the throttle body?

that.
Do the search using pcv valve... Plenty of options posted.

I just run these little filters on both valve covers. Take a look at the pic.

Well I guess I will try running the little filter on the passenger valve cover and the PCV valve on the drivers valve cover to the top middle (on drivers side) of the truck intake.

Thanks to all who replied. Looks like this is another one of those "do what works for your application" kind of things.
