for 35 plus years I have installed "breathers" in each valve cover and of course, some valve covers accommodate and seal better than others but overall, that set up is mostly what you see on sportsmen drag race builds.

So in a quest for options, I have the idea of putting two AN fittings in the "valley area" of the intake then using hoses to a remote breather tank. In doing so, there would be no openings in the valve cover. Oil fill would be some kind of threaded bung somewhere on the intake.

Of course we are talking about a trailered drag race car with an intake that allows access to the valley area. [example, a Super Victor style intake]

Let me have your thoughts about this idea.

Its only a breather so in reality you could put it anywhere you want, only important thing is to keep it away from oil.
But on that note, whats the problem with them in the rocker cover or are you just into doing something different.

it is an idea to consider for appearance reasons.

Simply looking for another, cleaner way to vent the engine. Even a more modern, high tech look but accomplishing the same thing, venting the crankcase.

I have in mind an aluminum vent can by Peterson or Steff's with a K & N breather and AN fittings. Maybe mounted on the front engine plate.

What about taking it of the manifold under the carb, run some hard stainless tubes from there to around the back of the head. You could even weld some blocks onto the rear of the manifold near the chev dissy, then drill from under the manifold and then drill from the rear too meet that hole. You could do it heaps of ways, The NOS guys have some excellent hidden systems that could could look at and get ideas from.

No EVAC system or vacuum pump??? FYI, there is horsepower there!

FYI, I tapped a 3/4" NPT hole in the valley of my Dart intake about 4 or 5 inches ahead of the distributor hole and that is where I put oil in. That hole is under the rear bowl of the carb and a long funnel reaches it OK.

I put a -10 or -12 bulkhead fitting in the FRONT of each fabricated aluminum valve cover (did I mention that they were cheap) and then piped it back to the EVAC system on each header. Being in the front like that keeps oil out of of that line. That and I also made a 3/8" thick aluminum fuel pump block off plate that is tapped for 3/8" NPT with a breather line connected to that also. You do have to be careful using that one though as you may get oil up in that area with no fuel pump push rod in that hole.

Larry,
Remember the old 283's had a canister (oil separator) in the lifter valley that was vented down beside the bell housing, with an angle on the end of the metal tube to help pull (a little) vacuum at highway speeds. The point being, it's a valid location to put a breather, but I would want some type of oil separator in the system. Let us know what you end up doing, I'm putting a vacuum pump on my new 555 and I'm considering the same area.

I was thinking the same thing. Kind of reinventing the wheel. It was a good idea but the EPA changed it. I would go with the oil separator also.
