If the line from the charcoal canister is present and missing its connection at the opposite end, and the solenoid nipple is broken off of your manifold, you should be able to find another loose vacuum hose with a solenoid attached to it... and possibly a vacuum nipple broken off in the hose... There's an electrical connection to it as well, so unless you're throwing ECU codes for it being missing, you're right... it should be in there somewhere.

 

This pic is out of someone else's thread. Notice the nipple protruding from the runner #1 location on this B16 manifold... peeking out behind the brake booster line... that's where the solenoid is supposed to connect.

 

Hmm..odd. My manifold has the bump where the nipple would be, but no nipple. It's compeletely sealed off like that's how the manifold was casted.

 

Bumpskie?

 

The EVAP purge solenoid should be on top of the intake manifold towards the firewall. Should be visible and the manifol nipple is just right inder it. You may know this but the JDM intake manifolds do not have a place for the EVAP purge solenoid. Make sure it's not JDM. I have done many JDM swaps and had to tee a vacuum source for the EVAP purge solenoid. Hope this helps.

 

My old D15B7 engine had the purge selenoid. My B16A is indeed a JDM one so I see now that it wouldn't have the spot for the slenoid. I think I'm thinking of the same thing as you. It's on the right side of the intake manifold if you're facing the engine bay and has the charcoal canister hose hooked up to it, or right under it. But yea, on my JDM intake manifold the spot for it isn't even there. So...what should I do? If that is it. Am I all set? I've been running the engine for about 4 months at the end of July without any problems what so ever.

 

It is just an emissions thing so if you aren't worried about emissions, leave it and cap the nipple on the canister. It has no affect on performance. If you really want it hooked up, grab the purge soleniod from your other motor and T off a vacuum source or get yourself a USDM obd1 B16 manifold. Good luck.

 

If the evap purge canister isn't hooked up, then your car might smell like gas. That's all it does is remove that smell by venting evaporating gasses from your gas tank into your intake manifold to be burnt. When working properly, it's what puts a vacuum in your gas tank.

 

Ok, well I passed emmissions like 3 weeks ago so I guess I'm all set. I'll continue to look into it and eventually fix the problem. Thanks a lot guys.
