Hello,
I have an eg with a usdm b18c1 swap. I just got it so i don't know the history of how it was put together anyways, the throttle body doesn't have the snout for the line to the evap canister and the evap canister doesn't have the dome with the snout that connects to this line. The canister only has the purge and the vapor return line on top and the fresh air in on the bottom. Please see image. Does anyone know why there isn't that line that goes from evap canister to the TB? I have a leak in my evap system which is why i looked in the manual and the manual says there should be a line connecting the two.
The picture attached show the TB with no snout circled in red and the green square indicates the evap canister with no dome. The cannister says tennex on it.

Please help.

 

Is the MAP sensor just unpluged?

^^ yes the map sensor was just unpluged so you can see the missing snout on the throttle body. I've noticed on that link that you sent, the snout on the TB appears to plugged up. Is that correct? Also, where is the 3 way valve? I don't believe 1992 civic have this. I know the 2 way valve is by the gas tank.

 

it doesn't have one because obd2 cars have a different evap setup. you probably don't have a fast idle valve under the tb too, correct?

 

^^ Acutally I do have a fast idle thermo valve. You are right, i think OBD2 cars have the 3 way valve whereas the EGs have 2 way valves.

The link that was posted mentioned that, that was a typical diagram for 94-95 integra and 1992-95 civics however it also mentioned 3 way evap which is odd.

 

92-95 Civics with a B18C1 swap, meaning you swap everything you need for the B18C1. 94

 

Hrmm i'm not sure what you are tyring to say here.

 

Correction!

I just went outside to check and my car does NOT have a FITV. But it does have coolant line going into something below the TB. however it doesn't have the big dome like the ones i see online. So i take it my throttle body is off and OBD2.

 

So the question now is what evap canister is that from? It doesn't look like an integra or civic or OBD1 or 2.

 

The link assumes you are doing a "proper" swap, swapping everything that is needed for the B18C1 engine and not "jery rigging" or bypassing anything. 94

 

I see... Hrmm so why did they show a picture of an OBD2 GSR manifold? Weird. Ohhh well...
