PCV System from magazine build? Is it OK?
PCV System from magazine build? Is it OK? SuperChevy built a budget LS motor a while back that I am linking below. On page 3 it shows a flat valley cover on which they installed a baffled PCV valve in the rear and a breather in the front.

The differences between my engine and the one in the link are that my build is a 408 and it has the same carb style intake but mine is the fuel injected version. I have the same valve covers which I do not really want to modify unless necessary. As simple as it looks I am sure there must be drawbacks.. I do not know enough about PCV systems so see any inherent problems. Can someone point out the pros/cons to me please. This is not a daily driver car.
Thanks ahead of time.

Any thoughts from anyone? They welded a baffle under the PCV and I suppose the breather as well.
How about this baffle? http://www.summitracing.com/parts/BSP-RP956034/
Kinda hard to tell how big they are and if they would fit.

I've never seen a set-up like that. If they hook-up the PCV valve there will be a vacuum leak. The breather is a very good idea. The PCV is not; unless it's being hooked to a vented catch-can without vacuum.
Turbo Buicks.. used that same type of PCV arrangement 20+ yrs ago. Worked just fine.
Thanks for the replies. I like the old school clean look of it since the 408 is going into a 69 Camaro. My thoughts are to make sure it is well baffled and if I get oil in the intake insert a catch can between the PCV and the intake.
The engine will be controlled by a 2001 F-Body ECM with a MAP sensor mounted to the intake.
If there is a vaccum leak would the ECM pick this up and throw a code with this system? Do ECMs sense that sort of thing? I am out of my element on this subject. How do I make it where there is no vaccum leak?
Does the fact that the build in the magazine was a carb set-up and mine is a fuel injected engine make any difference? I don't think it would but just asking.
