I know what you're thinking, OMG another catch can thread.

Well, after about an hour and a half, I thought I had it all down, but then I saw that all the threads and setups were for B-Series only!

I was looking at copying the Endyn setup but will those freeze plug/nipples work with a D-Series?

If that won't work, what's another easy way I can do it?

 

Block off IM nipple.
Run new line from black bose and point it at the ground.

Run new line from valve cover nipple and point it at the ground.

DONE


^What about that?

How about, take out black box. Machine fitting to fit in the hole. JB weld it in there, then run that line and a line from the valve cover to the catch can.

The fitting from honda for the b-series can be machined down to almost perfectly fit in that hole. Add the JB weld for extra support and it should work just fine.

 

I was never quite clear on the black box... what exactly is it? I read the big thread and got most of the information to build my venitlation setup but for some reason that part escaped me.

So do you still have the PCV hooked up? Should I remove the vacuum line going from the intake mani to the black box along with the PCV valve and plug the nipple on the mani? And then run a line from the black box to the can?

 

OK, so this is what I'm thinking.



I will cap the nipple on the intake manifold and then remove the PCV valve and hose. Then, as you can see, run a hose from the black box to the catch can along with two from the VC.

The catch can will be topped with a breather filter.

or ?

 

That should work just fine.

Dandy.

This is for a turbo application, BTW. Pushing 18 psi at the most. Sure it'll work with the PCV gone and everything?

Why do all that? The black box is a catch can.

I did exactly what he suggested and it's worked fine, except you have to make sure to remove the PCV valve:

I guess you're right. I could just vent them to the ground if I am gonna vent them to the can anyway.

Just stating that is an option if you want to get rid of the black box. I like it because it cleans up the back of the block a little bit. Either way will work just fine, so it really doesn't matter.

 

So would you reccomend running a can or just dumping to the ground?

Any effect on the way it works? I am thinking a can may be better cause I can see if I'm losing too much oil or something.

I like the catch can method. It lets you actually drain back if the can gets full and what not, but you can kick out a lot of oil, if you have a lot of blow by. So the can could get full depending on the boost and the level of blow by you get. I just wouldn't want it all over the bottom of my car, so I would run a catch can.

 

Hopefully I won't have alot of blow by!

 

Mine is setup like rota's. Back of valve cover but my can is mounted on the firewall.
Draining to the passenger side fitting on the block.

 

Slash cut tube inthe exhaust. Block off the valve cover. Pull a hose from the nipple onf the black box and run it down to the downpipe behind the O2 sensor. Better than anything else.

 

i was going to do a setup like rota's with the -an, but i might do one like the bottom with just the regular bungs. I wish i could get those in 45's though, o well...i guess thats why hoses flex lol

 

If you look in the head, the return hole the black box is on has high ridges around it, meaning you need ~1" of oil puddling in the head before it chooses that route. The other 3 holes should evacuate the oil quick enough, assuming you don't try any 5th gear top speed runs (sustained high rpm for long periods).

I'd suggest you just use the black box itself. Maybe gut it a bit, as I think there's some sort of matting in there, but you can just stick a barbed nipple in there like stock, but run it the catch can. Saves the time getting the right fitting for the hole, and lets any loose oil fill the box up before you catch can.

 

This is my setup. Black box to catchcan, valve cover to catchcan, then to pre turbo slash cut. The intake manifold nipple for the PCV is plugged and PCV is no longer in use. Works for me. The can I fabricated myself and has a baffle down the middle as well as some steel wool for filtering. I tapped the bottom and added a drain which is emptied every couple of months..




Black box to catchcan

 

i might do something similar until i get it going and get some more moeny to go -an off the valve cover
