A few ?? so i can finish up my 3rd gen swap! Options

[MGCustoms325]

Hi all,
Hopefully some of you that have completed your 3rd gen swaps will be able to help me ID a few things. If it makes a difference I am using a caldina IM on my 3rd gen 3S.

First, I need to ID what this hose goes to and what it does:



Where it is connected to the head



Next I need to ID this plug



And finally my mechanic wants to know what to use these for





And just to show my progress thus far:



Thanks!

Here's some hint for the intake manifold ports :



The port #1 is the Idle Air Control Valve inlet. It should be connected with a hose to the air intake (somewhere between your air filter and the turbo compressor inlet).

The ports #2 are the coolant routing for the throttle body. It keeps the throttle plate from freezing under very cold condition by passing some hotter than ambient coolant around the throttle body. If you live in a hot climate and never see less than -20°C, you can keep them unplugged. Be sure to plug the corresponding nipples on the coolant pipes.

The port #3 was originally connected to the BOV. It's how I'm using it currently.

In your picture #5, you are pointing at the PCV valve intake manifold nipple. It should connect to the Positive Crankcase Ventilation Valve (PCV valve) that is located on the top of your valvecover.
