How can I delete these pipes on my rb25det?

[Frozengrip]

Hello guys, so I’m looking into cleaning my engine bay and adding some goodies while I’m at it. I want to add a nice catch can setup with some braided lines running to it, so I’ll be adding some nice valve cover fittings. Issue is what is the pipe that is connected to top of the oem fittings do and how can I delete it? I know it connects to the turbo so I’m guessing it does something with oil? Hey guys hopefully you can understand what I mean, I also left a picture highlighting the pipes I meant. Thank you

The one from the rocker cover is your crankcase to intake pipe, the other is the factory BOV return pipe

So you can delete the BOV return pipe, but if you simply delete the breather pipe, you will have to make a proper effort to deal with the new crankcase breathing problem that you have created.

Luckily, there have been thousands of posts on this forum about this.  So search and read learn and then do.

Thank you guys for telling me exactly what they’re meant for. And gtsboy I will be doing just that, but with the fittings I’ll be buying only have one outlet opposed to the oem one with 2. Unless I can connect it somehow the bottom of the intake. I’ll see how I’ll reroute once I read and learn. Thank you guys much appreciated

Both the fittings from the cam cover to the catch can then a line from the catch can to the intake. So instead of teeing them at the cam cover fitting (factory setup) they are teed in the catch can

Bit hard to see in the photo but can kind of see it

Hey thank you Cal! I got some fittings similar to yours just have to wait for them to arrive ? but thank you for this made it so easy! Now as for the intake pipes think I could get some metal ones like that to fit on my stock turbo?
