My rear line is going to the rear valve cover port. and the front line is going to the turbo inlet just in front of the front intake runner. looks like mine is attach to a 90* plastic elbow. the shape....eh well it's curvy..lol. It has a plastic net protective thing on it. (the one that goes to the valve cover port)

 

1) There are two ports on each valve cover
2) The rear valve cover ports connect to the metal hardline on the front of the intercooler.
3) The hardline on the front of the intercooler connects to the Turbo Inlet Pipe.
4) The front ports on the valve covers run up and under the intake manifold and are connected together. They are ALSO Tee'd into the actual block.
5) The PCV comes out of the block and is Tee'd into both the intake manifold and the turbo inlet pipe (using check valves to protect against boost pressure).

Excellent, thank you!

I just installedthe perrin inlet while swapping the motor in, so it threw me off. Maybe it's just me, but the perrin instructions are awful.

It appears to me that they have you remove the grey check valve. Is that safe? I've been searching around for other turbo inlet install instructions, but I haven't found any mention of that.

Also, there is a small white nipple on the passenger side of the throttle body... what does it connct to?
