While the intake is off...?

I'm thinking that don't go to a/c I'm thinking it's smog pump or something else. I only had 2 tiny lines like that on mine one was to the smog/A.I.R. pump under the a/c compressor, the other goes to the egr solenoid.

That may very well be. I'll check it out and see what it is, but in the meantime, I'm more concerned with my rusted manifold bolts and getting everything squared away. I'll make sure to post back about what that little tube was.

You should change that heater hose fitting while the manifold is off... i didn't on mine cause i was in a hurry, now i know im going to be doing the whole job again someday when that fitting leaks.

Good point on that fitting. It's definitely a piece.

Well, I had to buy a pry bar, but I finally got the intake off last night. Besides some rust in the coolant ports, it didn't look too bad. Some crap that was around the edges of the manifold fell into the engine, so I'll be taking a shop vac to it.

So I pulled out my FelPro gaskets for the intake and realized that the rear coolant ports are almost entirely blocked on the gaskets (there's a small hole), but the ports are open on my block. Is this correct? I had the engine rebuilt by an engine shop about 8 years ago, so I don't remember whether the rear ports were originally blocked.

EDIT: And I do have the stupid heater hose fitting coming off the rear that goes to the heater core. I'm not sure if that changed through the years, but there it is

Sounds right to me.

Thanks, I forgot to reply back, but I found the answer after much research on Google
