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.
