can someone explain how, on an inline motor, does one obtain full crankcase ventilation with the breather AND the pcv on the same valve cover? if you do this on a v8 the eyebrows of others will be skewed and lifted. baffles or no baffles wouldn't the air travel (mostly) from the breather to the pcv? just curious as i was looking at my valve cover going on the motor.

On an inline engine, everything's...in line! There's enough airflow despite the inlet (breather) and outlet (PCV valve) being on the same valve cover. With a V-type engine, if you had 'em both on one bank, the other bank would be a "dead zone" with no airflow.

It works great with the tall chrome valve cover. You get lost of ventilation and airflow. My PVC stays very clean. I have a large K&N for the inlet.
Send me your email and I will send you a picture.

In the real world, though, fresh air is essential to proper crankcase ventilation and significantly improves oil and crankcase cleanliness.

i guess i am just not seeing how the air exchange above the rockers really affects the air in the down in the crankcase. i know that the airspace is essentially all connected but only through the "lifter access holes" that are partially obstructed by the drool tubes. and with such a small amount of vacuum drawing from the baffled breather across to the pcv how is this AS EFFECTIVE as the v8 full ventilation from one side to the other. seems like a breather down low on the crankcase would be a better solution to evacuation.

Air is constantly being added to the crankcase due to blowby (there's always blowby....).

That air makes it up to the valve cover and gets sucked out.... (less air goes in the breather than out the PVC.)

You're forgetting the significant windage generated by the spinning crankshaft and flying connecting rods.
...which is more than enough for adequate air circulation.
Well, Volvo set up their crankcase ventilation that way. And yet, we have forty-seven years of real-world data showing that the factory setup works quite well enough. Not only on slant-6s, but also on inline engines — four, five, and six cylinder — from numerous other automakers round the world. It's worth noting that the Volvo setup hasn't got a better service or efficacy record than the Chrysler setup. The Volvo setup has issues of its own, one of which is that the low location of the oil separator/flame trap means it is not only leak-prone but also more prone to clogging, and so must be serviced more regularly, than the high-mount breather on a slant-6.
