sbc crankcase ventalation....

[awsomeears]

Currently on my 400 sbc I have just 2 open cal custom breathers on each valve cover, no PVC or no filler neck on the front of the Manifold....

Last year while I was on the Freeway it was misting from one of the breathers, this got me thinking about adding a PCV system, I would make it simple and hidden so the engine bay still has a good look to it.

But my manifold does not have a fill in the front of the manifold, these fill tubes usually are breathers as well or at least let natural air in the crankcase while the breathers on the valve covers push it out.

So my point is what the hell should I do, do I have to drill the front of my manifold ? or can I just hook up a PCV into a Y and tap both valve covers and tap the 1 line into my intake ?

Point of a PCV is to keep the crank case clean as well the Oil from getting nasty or so I think, well I want clean oil and a clean internal motor

I will be running Velocity Stacks and not a true inclosed Air Filter, Filter element yet but no inclosure !

Googling brought up this... this was what I had visioned in my mind, of course the breather will look more classic and the pcv will be tapped in the rear of my valve cover and I'll tap my tunnel ram in the back

-AN tap the back of the valve cover(s) and route it into the air cleaner? Possibly with a catch can on the firewall in the middle?

I will be running velocity stacks !!!

I should note that !

OK, then just use a vented catch can...

In the middle of my tunnel ram is the center obviously but its center to all of the runners, I think this will be the best spot to tap for vacuum, I'd rather have my crankcase breath evenly to the tunnel ram.

I'll bend up some nice Aluminum and keep it classy !

So on the drivers it will be a Breather/Filter and the pvc on the passenger, that should take care of the in and out effect
