RH exaust on 1984 Blazer

[blazingtools]

Can anyone verify this for me?? I have a 1984 blazer (california model) and I am trying to find a new exaust manifold to replace a cracked on. All the ones I have found have air injection ports, which weren't on my origional truck. Can anyone verify, should my truck have air injection ports on the right hand side or not. Thanks

I'd have to say yes, my '83 non-CA did.

What's the emissions sticker on the core support show? If it shows AIR, then it should have the AIR manifold.

my 87 has the AIR. why not spend a few extra bucks and get some headers?

It does in fact have AIR, but it is plummed into the LH side. My confusion comes from the fact that all the replacements that I can find have it on the RH side, and my origional didn't. Since I'm not the origional owner, I'm wondering if something was changed, or its supposed to be only on the left.

FWIW, the AIR system on my 84 was connected to BOTH exhaust manifolds. I eliminated the AIR pump and simply plugged the holes with 3/8"(?) threaded plugs.

Why not just order the AIR manifold and plug the holes up?

I've never seen A.I.R. on just one side. Get the manifold that fits and plug the offending hole.

I would just plug the holes, but I have to pass smog

Anyone with an 84 have a picture of the RH side with the AIR routing and connection to the pump so I can see how its supposed to be.
