[KCD16Y8]

Hey Guys, I'm new to the forum, I'm an older Honda tech now retired. Just reaching out regarding a head swap I did on my wife's car. Its a 99EX Manual. Sent the head off to machine shop to discover it had a crack. I picked up another used head thinking hey all 96-00 D16Y8's are the same well...….

So I put the 97 head on her car and first fire has a high idle, I can hear a vac leak but cant find it.

Came on this forum and went wth is air injection haha. Here begins my problem haha.

So its a manual 99 EX I used all the OE equipment from the car minus the head is a 97. What should I do about going forward?

Pull intake off and plug us the 5 air injection holes on the 99 intake. Re-use the 99 IM gasket, not sure what else I would need to plug.

Or should I just get a 97 intake manifold?

I don't think the car will pass CA emissions in Comifornia but that's whatever.

I guess my question is what should I do as far as repair goes: It would be nice to not have CEL as well.

What's the most factory replacement program using the wrong year head lol.

Thanks for your Help!

tap the holes and put in some threaded plugs with sealant. should be the easiest thing to do

Thanks for the response. You think that if I pull mani and only plug up those 4 small holes, and the one larger one in the middle (probably just cap it on the top of the flange) everything should run as normal? No CEL's etc?

I should be running the same 99-00 Intake manifold gasket I'm guessing as well.

Thanks Again!

if the 99 doesn't have the holes in it, use it. that will do the same thing with the gasket.
