Doug,
This is interesting, and looks a lot like my buddy’s 428 system. How do I figure out where all those ports go without having the intake in my grubby hands?
Thanks,
Evan
Evan, a quick Google image search and I came up with the picture below.
If you look closely, just in front of the big hole at the back of the intake (that hole is the 'breather basket' hole), just beside the throttle bracket holes, you can see a bung or port that goes into the rear 2 intake runners. That hole could be used for vacuum operated stuff by putting a fitting with nipples in, or you could just put a pipe thread nipple on there and run the PCV hose to it. You do need to make sure that the PCV valve at the valve cover isn't pulling in oil mist or spray though. That's why there is usually a baffle under the hole in the valve cover.
The only downside to doing it that way is if you ARE pulling in a heavy oil mist, it may foul out that cylinders plug over time (the cylinder or cylinders that that port feeds). A closed element air cleaner usually has a fiber filter that goes over the hose end, as it enters the air cleaner housing, to stop some of that mist from being sucked directly into the engine. But as long as the PCV valve is properly protected from direct oil spray/mist, that shouldn't be a problem.
