i need throtle body pics from an 88-91 si... I also need a pic from the hose that comes off the valve cover and goes into the intake. There is a second hose attached to that hose and i need to know where it goes... My MPFI swap has not been going well and it seems that none of the manifolds i have seen look like my manifold... i have been to honda twice and a third time is most likly in order...i just need to see a civic or crx si or even an HF engine bay and i should be able to finish, and get my car running... Thanks

-BTW i have an 89 civic DX 5sp...

 

you can eliminate that pcv vlave by putting a breather on the part that the lower hose connect's to and that way you dont havta wory about it going bad ever agan

 

those hoses aren't really attached, just run next to each other to transfer heat from one to the other, you can elininate that transfer tube and just run a hose from your valve cover to your intake the other line is a coolant line that if I remember right runs from your thermostat housing to the bottom of your throttle body. I'll go out and double check that today, and try to get some pics if I can.

 

if it runs from the thermostat housing to the bottom of the throtle body, what goes to the nipple next to injector #4????
Thanks.

 

just get some 1/4" fuel line hose, about 6-8 inches of it, stick that on there...that's what I did.

 

yes...one line runs from the intake to the valvecover--the other is coolant and runs from the small coolant line on the intake manifold to the TB. i believe that is what you mean by nipple next to injector #4.

 

WOOOOOHOOOOO!!!!!!!!!!!!
I figured it out... i stopped a kid on the street today when i saw him getting out of his 4g hatch started talking to him asked him to pop his hood... He had a ZC in there and i traced his lines to find out that, the line next to injector #4 goes to the throtle body and the extra line goes right below inector #4 to the EACV sensor....
i am way stoked i order a longer hose from honda it should be here tomarrow... I am going to try and start see if any codes show up and leak some coolant on my floor....
Thank you all for you help.
