this answered most of my questions in very few words, i think its a very simple layout to help people understand. now to search for one like the bsh plate corey has. maybe ill make one.

added image of different options below. I created the 4th option from eurojets images because some people run it that way too.

is the block milled out to connect the two ports where i have the green arrows drawn? what about the port where the red arrow is, i assume its just blocked off? the reason i ask is because it doesnt seem to be easy to find a plate like the one below. it seems clear on this style that the oil and water vapor coming from the valve cover is vented and the crankcase gases that used to come to the rear most connection up get vented away



most of them have 3 ports(not shown) or 1 at the very rear like below. on this style i know the two front ports are connected in the plate by a milled void and the rear stock hose just plugs back on. Where does all that oil and water vapor go that is just being recirculated in this style? The crankcase vapors are still coming into the engine. Does this style dump more into your rear pcv potentially putting more oil into the intercoolers but the advantage is replacing the "Weak" stock front pcv system that can cause a boost leak?

In your first picture, that setup is retarded lol it bassically like you stated, just dumps the oil vapor directly back into the intake via the rear PCV lol

I guess the benefit being you have essentially eliminated your front PCV....


Now the second setup is the infamous block off plate
If you think about the design, how you buildup all your crankcase pressure in your Valve Cover... Now it makes sense why that particular plate is infamous for causing smoke to billow from your exhaust.

Bassically BSH was retarded in design, but I appreciate that they tried to offer something and were pretty much the first to do so.

If you do that, it's easy enough to block the rear PCV as well, so the issue is fixed right?
I have eurojet plate and a blocked rear PCV breather hose.

well it needs to vent somewhere. you would not want to block both off without some kind of vent. and Shane was saying that pushing that stuff back through the valve cover could be a cause of why it causes some cars to smoke because it builds up too much pressure. I like the eurojet plate you have and the bsh plate that corey has but i cannot find any like that. Who still makes them?
