ok i recently picked up a complete b18b1 for $150 and i will be swappin it into my 95 civic coupe ex, i was looking at it and the block doesnt have a black box or the hole, its not like its missing it it just doesnt come with one apparantly!

how does the pcv system work on it then?? the engine is taken apart and its missing the pcv valve on the valve cover and the whole pcv system also! please help me

can anyone please help me!! i have no idea how to set up a pcv system without the black box!!! PLEASE

the pcv valve tube should go straight to the intake manifold. im guessing the black box you're talking about is the oil breather. it doesn't come with one so don't worry about it. hope that helps.

On the 96+ LS engine there is no breather box because it vents the crankcase through the PCV on the valve cover and connects directly to the intake manifold, if you don't have one go get one from the auto parts store. Only cost a few bucks.

if i dont wanna get a black box @ an auto parts store, how should i set up a pcv system for a boosted ls??

He is saying if you don't have a Positive Crankcase Ventilation Valve then to go get one at an auto store.

If you want a black box I will give you one pay shipping but its not needed for your motor.

Look at the second set of pictures towards the bottom. This is the piece that I fabbed up to run my catch can system. This also eliminates my "Black Box" so I have an extra so to say.

how can i set up a catch can w/o having to get a black box or custom make my own fittings?? can i just run a vented catch can with two nipples, one going to the IM, and the other to the VC with the pcv??

sauceja

Without some ingenuity I would have to say search for topics with catch can setup or removal of oem pcv.

I am not very well versed in LS blocks so I can not provide much assistance to you from this point.
Sorry.

However there are alot of LSVTECs and alot of LS's out there and I am sure it has been beaten to death so I know info is around covering it. I just have not had a personal need to find it so I have no real knowledge with the subject.

If I run across some I will post links for you.
