Trouble Installing Intake Manifold

[likeold]

So I got everything cleaned up, painted, new studs and gaskets ready to install my intake/exhaust manifolds on my 38 special but they will not pull in tight. Seems the intake ferrules are causing the problem. They are all clean and mounted on the engine tightly. I thought maybe they were tapers but does not seem to be the case. I tried moving the manifolds around while pushing they just will not seat into the manifold? Any tips? I was thinking of a minor bevel on the ferrule with my dremel tool and some grease not sure though.

Has the manifold been disassembled.?

No

Yes, that's what was in there

I'm wondering if I really need the gland rings if I'm using copper gaskets

Yes, at least on the exhaust ports.

That's what I would think but the engine only has four on the intake manifold.

Did YOU remove the manifold?  Did you do anything to the manifold or the head? The intake is normally NOT a problem.  The exhaust is .  Sometimes.

This is a replacement intake/exhaust manifold, alignment could be slightly different.

What type of gasket, if any, are you using between the exhaust manifold and intake manifold? If it is too thick, it might make it difficult to get everything lined up to bolt together. I would try loosening the bolts between the intake manifold and exhaust manifold so they can move slightly and see if you can get the exhaust manifold to start to snug down around the gland rings with the two manifolds able to move a bit. I would recommend using the gland rings, but if you can't get the assembly to seat around them, you might try without the gland rings. I would suspect that the alignment of the two manifolds is just enough off that the gland rings are not lining up correctly with the intake manifold when the exhaust manifold is lined up with the studs.

copper gaskets

Try removing one of the end rings and see it it will go on. As stated, not usually an intake issue, but manifolds can warp a little over time.  If it appears close to aligned, just go with the gasket on that one.

Also make sure the gland rings are fully seated in their slots and even across the length of the manifold.  If the gland rings are new, you might also measure the width of the gland rings to make sure they are the same as originals.

Are the "ears" of the intake and exhaust flaanges the same dimension? If not you'll never get the 2 manifolds to bolt up properly

Okay guys got it all together. I put a small bevel on the outside of the gland rings then tried inserting one at a time and found the culprit. I ground a little bit more off that one. It went all together tight, no leaks and runs great. Thanks for the help!

See pic, reason for intake manifold replacement, rusted from the inside out.
