Gaskets/O rings????????

[Blestlove603]

Hey Folks, I have a random question and really am lost. I am trying to find out what the 3rd to last and second to last o rings are for and two identical gaskets above the injector o rings are for. Everything else was pretty straight forward. if the image doesnt load its the headset for my 2005 Grand Prix GTP. Part# HS9089PT-3. Any help would be awesome.

Those 6 untidentified o-rings, I'm not entirely sure but I would suspect they are for the vacuum cap/other assorted things that nobody removes unless they are broken; the two identical gaskets are for the EGR, one going to the LIM, one going to the rear exhaust manifold.

These sets always come with extra stuff that isn't necessarily needed.

injector and coolant elbow and lim coolant port o rings.

and there could be a na o ring or part tossed in there.

Thanks for the answers, So I used the two yellow ones for the LIM to SC coolant passages. I had new aluminium coolant elbows so I didn't use any of the orange ones. I used two of the black ones out of the 3 on the coolant hose connectors that go into the Main drive belt tensioner. And I havent done my fuel injectors until I bench test them to make sure they are good ( long story). I only have one "gasket" left and its the little blue one under the TB gasket. I think its for the MAP sensor but who knows. again Thanks for the answers really helped my from scratching my head any longer.
