Alright this is a simple and good read. It shows the 2 types of PCV setups. The open and closed. Newer cars use the closed systems where the
oil breather is not vented to the open. THERE IS NO BREATHER. The air is directed to the intake manifold. The fox body stang used this system. It never had a breather. Look at a set of Fox body valve covers. It provides the best pollution control and a nice clean crankcase. If you take a fox stang 302 apart at 150,000 it has a sparkle to the crankcase. Part of this is due to modern detergent oils the other part (larger) is due to the PCV. With a supercharged system the closed system becomes problematic since you can charge the crankcase with boost and make a serious mess. I know this from twin turbocharging. The
oil dipstick can fly out under boost. It's quite messy. The soln is to add a breather and take away the closed element. In other words don't feed back through the intake. The problem is this is not as effective for cleaning the crackcase. With the turbo's people experience the same problem you have. Baffles do help but turbo owners add another can. Run a line from the breather to a vented tank. The valve cover in not vented but the tank is. The tank collects the
oil and is periodically drained. The problem is solved. Lastly, if you only drive the once in a while then you will probably never have crancase build up anyway. You will have leaking gaskets though.
