Part Id Back Of The Rb25 Plenum

[Rob_C110GTR]

What's the green part on the back of the plenum?

Does that connect to the brake booster?

What size hose do I need?

That's a knock sensor. Not sure what it would be doing on the back of the intake manifold

Do you have a photo zoomed out a bit more so we can see where exactly it is?

I don't right now , but its right behind the plenum near the top near the throttle cable

It's a R32 with RB25det

Jut got the car so trying to sort things and tidy up.

It looks like the previous owner just used a knock sensor to block that hole

As they connected the hose from the brake booster to the port where the PCV valve used to connect.

And left the PCV port on the head cover open. Need to source a PCV valve grommet and the "s" hose

Anyone know what size is the stock nipple and thread?

Thanks

Unscrew the knock sensor and make sure it doesn't seem dodgy screwing in and out and if.not you can probably just take it to pirtek etc and say you want a fitting with that thread and a nipple on the other end? What hose do you want to put on there? PCV? Can't quite remember the hose size but might be 5/16? The thread should be BSP

I just want to correct the vacuum hoses

Right now the previous owner had the front port connected to the brake booster where it should be connected to the PCV valve.

So I need to connect the rear port (dummy knock sensor) and connect that to the brake booster. Then get a PCV valve working normal again
