I am using hondata s200, when it was initially installed the hose running from my PCV system was just hanging there, not connect to anything, should I connect the line to the back of my intake manifold?

Also, one line that comes off of my evap canister and goes to my evap purge control valve that is normally on the backside of the intake mani, that is just kinda sitting there by the canister, not connected to anything. The electrical is still connected, but the evap purge control valve is not, should I disconnect it all together? My old tuner said that I don't need it anymore, and well, it has been running without it hooked up to the IM, what should I do?

Basically my question is, should I take the evap system out, and should I connect my PCV valve to the back of my IM anyways?

 

so no one knows huh?

 

With a turbo setup, you need to properly evacuate the PCV system. Simply routing the PCV like it is stock is not going to be sufficient. Get a ventilated catch can and run fittings off the back of the block.

The EVAP system can go, though.

 

I have a catch can, but it's not connected to the PCV syste, it's on the tube that's sticking out beside the oil cap, and I have a hose extending to the ground on the other end of it, so are you saying I don't need to connect my PCV valve hose to the IM?

 

That tube is part of the PCV system but you won't get much evacuation from it. The way it sounds like you set up the catch can, you might as well have just stuck a breather filter on that tube and called it a day. Check out this thread and how they route the catch can from the back of the block: https://honda-tech.com/zerothread?id=1199935.

You can't reconnect that line to the IM because it will send boost pressure into the crankcase. Add that to an already insufficient PCV evacuation and you have blown ringlands.

 

Ive read that but I still don't understand a few things.. 1) it says to plug the original crank case breather in the back of the block.. there is no hole back there, just a channel that's blocked. 2) so i would just need 2 replace the two ports with the 14mm screws with new aluminum fittings with hose clamps and attach both lines to my car can?

It does not go into much detail, on the first part explaining with the b18 motor.

 

Then don't worry about the hole. I am assuming your PCV valve is on your valve cover, so you don't have a breather box in the back of the block. The fittings will be the same as any B-series, though.
