i was wondering if anyone could help me out with where the vacuum line goes on the b16 manifold. if i leave it un plugged, the car runs and drives on 3 cylinders but if i plug it up the car dies. i have no idea where it goes. i was informed that this is an older model manifold and that the newer ones dont have this...not sure...its the vacuum that is located in the middle of the manifold.

here a picture of it. its the one with the blue hose coming out of it.



any help would be greatly appreciated!!!!!!!

 

Can't find any B16 that looks like that. How long has it been this way? Where are you plugging this up to? When the car dies does it throw a CEL? Does it throw a CEL at any time the car is running?

 

well its a b16 intake manifold attached to a b16 head. the motor is acutally a ls/vtec motor and we just got done building it so i cant figure out where it goes. for now it just isnt plugged up. the car is throwing codes for vacuum leaks....anyone know where this is supposed to go?

 

it looks like a jdm b16a2 intake manifold

 

goes to intake tubing...

 

Probably for the purge solenoid

 

Duz it not go to PCV valve onda manifold flange between two runners

 

not sure...some pictures on google showed that it connected to another valve on the intake mani under the fuel rail in between injectors....i guess ill try that tomorrow. lmk if you think it will go anywhere else!! thanks appreciate the help

 

top port goes to the brake booster hose. the blue hose id say def goes to the pcv valve. do you even have one hooked up? if you dont thats where the blue line goes

 

where is the pcv valve?

 

hmmm im guessing i dont have a pcv valve since i read that only vtec motors have them? i have a b16 head mounted onto a b18b block. i read that you have to drill a hole and attach a nipple to the back of the block and have a catch can in between? can anyone verify this?!

hmmm i attached the blue hose to the valve cover and it does die as much...stayed running for a little then died once...

 

a b16 is a vtec motor. all motors have a pcv. you actually defined where its located about 5 posts up.

sounds like you started a project you never should have gotten into.

 

right all motors have a pcv but non vtec motors such as the b18 which i have has it on the valve cover. since i went ls/vtec b18/b16 i dont have a port any longer. therefore i dunno where it goes lol. you are right when you said i started a project i shouldnt have. haha i just connected it to the valve cover....works for now i guess

 

Can anyone give me a straight answer where this hose goes

 

That's a EM1 intake. Tried to look at pictures of mine but couldn't see where it goes from the pictures.


Could it be to the IACV? (Not the one with the red ring, thats the purge and not where this connects )


I can give it a better chek when I arrives from home.

 

I have the same manifold on my second Gen jdm b16a and it goes to the pcv valve under the fuel rail

^^ yes. it goes to the pcv. the small nipple on the back towards the drivers side is for cruise control.

 

Aaaah, I learned something there kyden thanks!
And I can now confirm that the hose goes to pcv under the fuelrail between cylinder 3 and 4

 

thanks alot lads helped me alot anyone else confused my b16a2 had a black connector coming up between the 1st arm of the inlet manifold mine looks like its snapped so will be running it straight threw the inlet on to the pcv box i can get pics if it helps. thank you lot again very helpfull. :D kbear whats that braided fuel hose you have got where did you get it from?
