Honda B-series engineblock/oil question?

[teh_mugen18]

On the b18 LS motors, there is a little black box around the back side of the engine underneath the intake manifold... Exactly what is that box there for?? Because, theres 2 holes at the top of it, but on mine, one of the holes is just open and it sprays pulses of crankcase air and tiny bits of oil out all the time. I can put my finger over the hole to stop the oil and it doesnt hurt anything, but i was wondering is this a part of the PCV system or what?:???:

yea it is. there is supposed to be little pcv valve in that hole connected to a hose leading up to your intake mani:..

its your purge valve and it ok the way you have it i know alot of shops that disconnect it there was a thread bout this at H-T

[.:Stirfry:.]

yea or you can have a tube leading off of pointing towards the ground..
or get a z10 block plug

thats the pcv valve box thingy. Traps all that extra stuff. IDK if its REALLY important but I do know it has to be. The PCV valve is important so I would assume u should keep it.
