B18a1 I removed my breather box and PCV valve and installed the BWR catch can. And I have this open ended pipe that plugs into the breather box/ PCV valve leftover that I circled in red. It's just gasses that come from the block. Would I be safe to run one of these mini air filters?

 

bump

 

if you are wanting to keep the outside of your engine covered in a nice thin layer of oil mist those work well.

 

would it be best just to remove that piece I circled in red and insert a bolt and plug it completely? Feels like you're condescending me haha that's why I asked the question. I wasn't sure. It's where the PCV valve plugs onto but I ran a BWR catch can that eliminates the OEM PCV valve and leaves that piece I circled in red open and unplugged.

 

Yes, it is better to remove the hose barb you have circled in the pic you posted and replace it with a pipe plug.

 

hose barb was the word I was looking for. But thanks for letting me know man!!

 

got a brass piping plug and a little Hondabond and it's sealed.

 

hoepfully you have some way to vent the crank case preasure elsewhere in your build.

 

it's ventilated to my BWR catch can/box

 

How the hell did you get your block plug in? Ive tried freezing mine, sanding down the o-rings, lubing it up, and obviously the combination of all three. Im about to return it.. It just wont slide in past the first o-ring, I feel like I exert any more force on it im gonna nudge the car off the jackstands lmao.

 

mine slid in just fine. You have the hole wide open right nothing blocking? And where did you buy the catch can? Directly from BWR? Or is it a mock BWR? In that case it’s possible it wasn’t machined correctly or made too big.
