there is these holes on top of my manifold that it looks like somethin goes in there and i dont know wat it is!!!! i need ur help to tell me wat it is because thats all im waitin for to get my car bak!!!

 

IACV?

 

but isnt the IACV on the bak of the manifold????? because i have it on the bak of the manifold.... some ppl say they use it to run a vacum line from the valve cover to there since they dont run it to the intake

 

looks like an exta vacuum port, just plug it, or get closeups

 

what head is it? try running a search on the head type and look for a diagram.

 

I dunno man, that's a y8 mani right? ( I don't recall that on a Y8 mani) Maybe someone added an extra vaccum port?

 

Thats not a y8 manifold. **** thats not even a D series head. Looks to be B16 with a skunk2 manifold (could be wrong on the manifold).

But like everyone said that looks like just an extra port. Is it just a direct hole right into the manifold with threads or no threads?

 

Its an LS head and LS manifold 2 of the holes r threaded and the big one is NOT!!!! so yeah help me out please thank u all

 

close up pic? Because there shouldnt be a hole there. OBD2?

looks like map sensor depending on the manifold... iacv is on the back on all the cars i've had (b16,b18b,b18a)
