Hi i have a 94 civic dx i just recently bought and the intake manifold had been rebuilt and replaced. when the previous owner put everything back on. not all the lines were put back in the right spots like the pcv line and the vaccumm lines. i have replaced and fixed those line but i have two lines that are cut that go somewhere and im not sure where they go. one liine comes off the throttlebody and it is a coolant line and its right under the intake connects to the manifold . i found a line behind the evap canistor that the linealso looks cut that goes down to a line that splits just beneath the firewall and the other line that is connected to it goes and connects to the bottom of the evap canistor and then i have a line that comes directly out of the firewall. looks like a big coolant line . its real flimsy and loose but i can seem to find where it goes. i will have pics of soon. please if any1 has any answers let me know thanx.

...you can click on enlarge or zoom and then print them out if it makes it easier.

 

hi thanks for the reply with the diagrams but my engine is a d15b2 do u hav any diagrams of that motor and how much similar is the d15b7 to the d15b2 ?

 

What engine is the D15B2? Is it a 16v or 8v? Also is it vtec or no? Is it MFI or no? Also, same with the D15B7? Once I know I can look it up because they dont have the engine codes listed, just what size and how many valves and if its vtec or not.

 

ok nvm I looked them up here:
