do you mean "dont" have catch cans

the dont have one lol...they just have a pcv valve which IMO doesnt do shit to relieve crankcase pressure...

dont quote me on this, but i think that there is a a big nut on the back of the b20 blocks that you can take out to but in a b series OEM catch can...

if you are doing an extreme build that is going to have high compression, just spend the money and get an external catch can
