Here is how I did mine. I tried to mimic the Endyn breather tank.
Parts needed
-catch can
-transmission cooler lines (they are oil resistant)
-hose clamps
-Honda part# 11107-PK2-003 you need 2 of them
-Honda part#90401-PR4-000 gaskets for above part need 2 also
There are to large plugs in the back of the block, ID them by the large allen head bolt style (I hade to by a large allen socket to removed these) remove then to open up the oil drain passages. This is where you crank case gases will exit. Install the Honda parts in the list in the threaded holes that you just took the plugs out of. Be sure to install the gaskets. The Honda parts are from a 00 Prelude SH oil cooler BTW. Find a suitable place to mount the catch can. Install and run trans lines from nipples on block to catch can.
Here is what I came up with and it has been working great for a few months now. I modified my catch can a bit so it will vent crank case pressure to atmosphere and so it will drain any oil back into the engine.




How I modified the Ebay catch can to work as a crank case breather can to prevent oil burning under high RPMs.
I first removed the drain plug from the bottom and retapped the hole for a 1/8 npt barbed fitting, this works to drain the oil collected back into the engine. This is done my running a 3rd line from the bottom fitting and Ting into the lower vent line. Since the gases need a place to vent from I needed to drill and tap a second 1/8 NTP hole to add a breather filter. That is pretty much it. Hope that helps you and anyone else out. I know I asked and searched for the best solution to not having a PVC once putting a Vtec head on my B18B1 block. This was cheap and has worked well for me.
