Hello honda tech
I came to you in hopes for some help. I'm completely done with my build just one hole on my b18a block I'm unsure about. I'm running a non drain back pcv system using endynes kit. With the two AN block fittings. There is a open hole where the stock pcv nipple goes. Can I just block this port off or what should I do with it?

 

i think water goes though that hole, well at least its like that on my b18c1

 

Lol just stop

Op block that hole off that's for the stock catch can

I forgot what thread it is
