blow by tube

[evolution23]

wondering if someone can shine some light on this, the blow by tube from the valve cover to infront of the turbo (circled in red) on the rb25, is it necessary or can it be blocked off and just run the line connecting the valve covers? (circled in yellow)



hopefully the picture helps as its late and i just had no idea how to word this. anyways, thanks for any help in advance.

Dont block it off, it vents your crankcase into the intake. You can put a breather on the end of it but its a $300 fine from MTO if you live in a jurisdiction with emissions.

+1. BTW - that's probably the best one line response I've ever read! Answers the question AND provides relavent caution.

lol yeah + the simple factor. guess its time to track down that black tube that goes from the top of the valve cover to the hard pipe as i may have accidentally snapped mine (which is why i was wanting to just block it off)

I have one kicking around if you want to pay the shipping
