Hi Hoping for some help from knowledgable eyes. I have a Subaru GL 87 1.8 Carb.
**I recently replaced the overcharging alternator (bad regulator). After timing belt procedure it decided to quit.
Overview of this engine-

1. Here is the biggest problem, rear of motor and of alternator area: This hose (below) is broken the engine shakes a little more after, and when i cover the hole it calms down. I found the possible piece ( top) Not sure where else it was connected to?

2. I also found this guy hanging around, looks like it should be bolted down, but what is this?

3. I'm pretty sure those are plugs for the A/C compressor. Looks like you don't have A/C, so that's why. I deleted my A/C, and I have those two plugs. Can't recall if they were plugged into the compressor or not though.

 

4. That plug looks like one of the CEL checking plugs. You plug it in when you wanna check the check engine light.

Cars usually only have a couple wiring harness made for them, regardless of the combination of options it actually had. So extra plugs aren't a bad thing. They could be for A/C, cruise control, and a host of other things.

 

 

Yep, that larger black connector by the strut tower is the diagnostic connector. It can be used to test a number of systems, but under normal circumstances, unplugged is fine.

 

Looks like that hose by the washer pump is just a drain.

 

 

Hopefully someone else can help you with those vacuum lines. Carbed EA82s are a nightmare in that department......

1 and 2 are parts of the Evap system.

 

1 shows the open port.......2 is the solenoid that should be connected there.....And should be bolted down to the open bolt hole in #1.

 

3, 4, 5 are unused connectors for A/C and a test connector.

Thanks, glad to have some idea on it all.

since 1 definitely promotes a better running engine when it is plugged, I'd like to connect or plug it, to be sure: #2 attaches via hole by #1, and then connects to 1? or 1 port remains open? There is nothing unhooked from 2 to be able to connect these together.

The solenoid should have 2 ports on it.  3 really....but the 3rd is open to atmosphere(the little capped end)

 

Look in the bent tube in the #1 picture.....I'll bet you find the broken piece of the second port.

 

That solenoid should connect the port on the intake to the Bowl vent valve  (UFO lookin thing in the pictures) and the T goes from there into a hardline that connects to the ACVV (UFO thingy on other side of intake not pictured).....

 

You can bypass the solenoid.....it will just vent the bowl and run the air bleeds at full open all the time....might affect warm up idle/throttle but not much.

 

Or you take the middle line off the "T" and connect that line to the open vac port.  Install the check valve between so that it can be sucked through by the intake....Leave the bowl vent valve hose open.

 

 

It's a simple solenoid.....and can be replaced with one from any number of newer imports......just gotta take a wonder around the pick n pull yards look for one with 3 ports one to atmosphere.

in 1.  the small hose is off the manifold I think. hence you cover it you stop vacuum leak. Think you connect that hose to it and it goes under the carbie base.
