if i need to extend any hoses i bought 5 feet of 1/4'' i.d. hose for coolant/fuel/vapor use

 

i know that the tiny tiny nipple on the top left goes to the top of the FPR

but then to the right of that there is a larger one

and underneath that there is another large one

and on the backside there is one that is like a 90' bend

and another tiny nipple on the backside...wtf

 

i think on the backside the tiny tiny nipple might be for cruise control??? i should prolly cap it off

 

:TU:

and the 90' bend on the back prolly is the brake booster

:TU:

 

and the 90' bend on the back prolly is the brake booster...so what are the ones on the front



ok everyone hates me ill go cry now lol

 

where do the purge control and the PCV connect to?


the pcv valve is the lil black thing thats a 90' degree bend...i was trying to figure out where the hell it connected to...

and idk where the purge goes....


also, i know the IACV one is a coolant line and the other is blank? and where does blank connect to? prolly a vaccum source?


and i totally gave you rep

 

mass rep for anyone with some help

 

i have this problem before
the back one u can block it off
the lil nipple in front is the fpr
the bottom big nipple is pcv valve

if u are converting to obd1 u have to trow the colant lines to the back of manifold iacv w/e is call

if ur keeping the y7 trottle boddy u need to extend tyhe hoses the nipple from the bottom of the head with is coming from the center of the block goes to the rigth one. the second one goes to the side of the head

now u need to use the y8 spring with the y7 throle body w/e hope htis hleps its easy

 

where does the pcv valve connect to? and thats the black 90' bend thing right?

im keeping obd2

i extended the hose that goes from the middle back of the block to my iacv already.

when you say the second IACV goes to the side of the head, are you talking the crankshaft vent thing?

and i got the TB working

 

and what does the pcv plug into

 

pcv valve goes in the black box under the IM, then routes to #2 on sql civic's diagram.

 

ok look on that pic, very top of pic on the back of the mani is the iacv- black looks kinda like a camera film canister. the y7 is a three wire iacv while the y8 manual is a two wire. y8 auto is three wire. y7 ecu will not control a three wire iacv. ive heard that if you swap the y7 throttle body onto the y8 mani, you can just plug the y8 iacv or just leave it unhooked(with itself becoming the plug). if you swap the y7 body, just rehook the three wire plug(i think the wires are orange black and blue) back up. then you swap the throttle spring and rotor from the y8 onto the y7 throttle body. and im not sure how yours will work, but in my setup(z6 mani) i had to purchase a y8 throttle cable since the throttle is now setup differently. oh and if you bought a 99-00 y8 mani, it probably has air injection holes, i think they need to be plugged. i know im forgetting something else, but i cant remember it. really just sit and think about it, maybe mock up the lines back on the y7 mani and compare to the y8 mani. you know find out what every line on the y7 is and does and then put it on the y8 mani. i literally put mine almost side by side when i worked on it. came out nicely. lastly, calm down a bit. i can literally picture you banging your head on the keyboard haha. you cant work without a level head and expect things to go smoothly. speaking from personal experience haha.

 

Y8 IM Hose Connections

1 - Fuel pressure regulator
2 - PCV valve
3 - EVAP purge control
4 - Brake booster
5 - Cruise control (It's capped cause I don't have it.)

This is a 98 Y8 IM.

^ BTW - What's a camera film cannister? :wink:

 

Diagram of PCV

A diagram is worth a thousand words.

 

A diagram is worth a thousand words.

see where the #11 is? that box right there. it's black, and the y7's do have them.

 

There's still tow more hoses... IACV, but those are pretty obvious.

 

is #11 the pcv valve? thats shaped like a 90' elbow?

 

pcv valve is #3.

 

Aye its right under where the inlet manifold is.
I had to chop my brake servo line to fit, but I've got a RHD car so it comes from t'other side of the engine bay.

 

oh ok, it just looks different than the y7's pcv valve

 

yea, it does the same thing. we happened to have a y8 one when me and my bro did this.

 

well im back to work on it, thank you everyone that helped and i left some reppage.

 

good luck! :TU:

 

fuck

man im still confused.....ok i looked up what the evap looks like and i got this

if im correct that connect to SQL CIVICS #3 and then the evap goes to a big black canister mounted on my firewall.


but im still lost on sqlcivics #2 I CANT FIND A BLACK BOX on his pic he has a big black box across his fuel rail, and i dont have one. is that the black box? because ive searched and searched but cant find one


and then the iacv...one is coolant, but what is the other

 

anyone?

 

#2 connects the hose to the pcv, which connects to a "black box" which is under the manifold and it's called the breather chamber

 

i dont see a black box!?

 

its pentagonal shaped @ the back of the block, near the water pipe....

edit: #1 on the parts catalog diagram....

 

ill report back in a minute, ive been searching and searching

 

the water pipe runs from the thermo housing right?
