Hey guys, So I got a general catchcan with two 6an fittings on it. My question is, I have only two ports, so I am trying to figure out what will be best for venting. I know stm sells the valve cover fittings to use 6an lines. They also have the 6an adapter for the balance shaft hole too.

Would it be better, to just get the two for the valve cover, replacing the pcv valve? Or would it be better to leave the pcv valve, use the factory vent on the valve cover and then use the adapter that goes into the block??

Whats your thoughts?

 

I would vent the block for sure, after all, thats where the worst of your pressure is since its in the actual crank case

 

It seems there is to many threads on this already. On another note, I would give some advice on this but it seems that not may people around here bother to look out side the EVO forums to see what the rest of the world already knows about this kind of thing, its sad. So my advice is to first search here, then or you can google search crank case vents.
