What does this do? http://paceperformance.com/ProductIm...s/19171224.gif
There is a silver metal pipe next to the throttle body coming from the cylinder head. [U.S driver side]
What does it do and where do I link it to? [think its something to do with water]
Also at the back of the inlet manifold there is a pipe coming off. What does this do?

Take the W.P. off the engine before you drill & tap it, to allow you to get all the metal shavings out. Thread in a 90 degree fitting, instead of a straight up fitting. Seal the threads when you do. Make sure you drill the hole for the fitting, offset to the far side of that flat top area of the water-pump, to allow plenty of clearance for the movement of the throttle cam/cable assembly.
This has come up a few times on here and there are varying opinions. What I did is leave it open until water came out then I just capped it off. Been running it this way for 10k miles and haven't had a problem yet. Many others have done the same.

So instead of plumbing it in you have blocked it?
Does this have any negative affects?
Also can someone explain to me what that pipe actually does because on all the other cars Ive worked on steam pipes dont come up?

There has been *A LOT* of discussion about this.
Way too much information and opinions to rehash here.
I would suggest going to the advanced search feature and search the word steam in the conversions and hybrids subforum.
You will find more information than you can imagine.

I like this solution done by Andrew aka.. Project GatTagO
I also routed the line from the coolant crossover tube. This tube can be routed to several places. The most popular is to run it to the radiator by the upper radiator hose. Others run a T in the upper radiator hose and routed there. On 5.3L Trailblazers the line runs to the large heater hose. So I drilled and tapped the water pump and ran a stainless hardline from the crossover tube to the water pump.

The last thing I want to do is get into an argument about this again but basically its supposed to help get rid of steam pockets that might get stuck in the head. I would consider this to be most threatening when one is first filling with fluids(which is why I waited for the fluid to come out before I capped it). I really didn't want to be drilling and tapping every time I replace a waterpump which hopefully won't be often. At any rate, the only time it should really be a problem is if you are running a high hp car. In fact some engine builders go ahead and connect all 4 steam vent holes on high hp builds.
