Re: Manifold Gland Rings
From Bratton's on-line catalog; The 4 rings that seat into the manifold and block to prevent leaks. Ford discontinued using these for a brief time in early 1929. If the manifold or block has been resurfaced, the width of the gland rings will need to be reduced by the same amount.

Re: Manifold Gland Rings
Yeah, I am definitely not an expert but I AM staying out of this one even though my opinion aligns with what has been stated above!

Re: Manifold Gland Rings
The "Green book" show 1928 to 1934 with a B part number. As of it's printing in 1948 they had been discontinued being supplied thru Ford.
Ruth thank you for the correction on the year.

Re: Manifold Gland Rings
If gland rings are not used it will usually just be a matter of time before the exhaust manifold will begin to sag at the rear and need replacement . I'm fixing to install a new exhaust manifold on our roadster . From now on , I will use gland rings .

Re: Manifold Gland Rings
New exhaust manifold..use the rings. Old manifold..maybe not. Particularly if it has been milled, etc. The engine block side will be deep enough, old manifold, maybe not.

Re: Manifold Gland Rings
Here is a third recommendation from a third vendor.
A9440 GLAND RINGS THESE RINGS GO IN THE EXHAUST PORTS TO HELP WITH MANIFOLD GASKET LEAKAGE. WE RECOMMEND THAT ONLY THE 1ST AND 4TH HAVE THESE INSTALLED Units per Quanitity ( Set ) In Stock

Re: Manifold Gland Rings
The timing for this thread couldn't be better. I'm was just in the process of reassembly when this thread started. Didn't even know "gland rings" were a thing. Since my manifolds are new (400 miles on them), and after reading all the comments, I decided that these rings are a good idea so I made some up on my lathe. Henry Ford wasn''t one to spend money where it wasn't necessary so if he thought they were not needed, he wouldn't have included them. Plus, the concept seems sound to me. Time will tell I suppose but pretty easy to remove if, for some reason they don't pan out. The reports of them ending up in the muffler are baffling to me. Unless they had a WAY too big of gap, it doesn't seem possible for them to come out that I can see. I WAS going to just make them solid with a snug fit but decided to make them a few thou oversize and cut them with a hacksaw to give me a little flex for ease of install and still have a snug fit. Ended up with about a .0010 gap. I read somewhere that without a gap (1/16" IIRC) they will expand and buckle and end up in the port. I'm not so sure about that since it seems to me that any pressure would be equal (due too them being round) and if they DO buckle it would be at the gap. If this happens, I can always make new ones, either with more gap for expansion or no gap (Make them a snug fit without cutting them). Anyway, thanks to the OP for starting the thread and thanks to all that responded.

Re: Manifold Gland Rings
I suspect someone here has the Ford drawings/specs.

Re: Manifold Gland Rings
I'm with Steve Becker..no modern application uses them.If your worried about your manifold drooping you need to rethink your priorities,that shouldn't even register on the list of worries driving a model a..
high temperature silicone sealant will help those with manifolds that aren't perfectly flat,tightening the nuts a few times,like torquing a head after a head gasket replacement, helps too. |

Re: Manifold Gland Rings
I can think of no modern application where 4 bolts hold both the exhaust and intake manifolds in the center and leave the end (with no support) to hold up the weight of the muffler and pipe.
And where did Steve state that "no modern application uses them".

Re: Manifold Gland Rings
"I'm with Steve Becker..no modern application uses them.If your worried about your manifold drooping"
Steve said Ford only used them in 1928. Modern applications used more bolts/studs through holes in the castings, not 4 studs and washers to support both manifolds leaving the tail end of the exhaust manifold more or less hanging. If there is something in the Service Bulletins or the archives about them not being used after X date between 1927 to 1934, besides the info later in the 1948 Green Book, that would be different story. Re the rings found in the exhaust pipe; there were some poor copies made years back that just kinda rolled themselves into a ball when got hot and dropped down in.

Re: Manifold Gland Rings
If that were true, why is my brand new manifold ported for them?.

Re: Manifold Gland Rings
Easy boys its just my opinion,I tolerate yours...the gland ring does not increase clamping force,it holds alignment.Droop is an issue? Sure, but not a major issue
Silicone is a modern solution to many issues with early engines if used correctly. One of the reasons I raised compression,added fuel,run a header and use a mechanical advance distributor is increased efficiency, my engine and exhaust run cooler than a stock engine.A cooler exhaust doesn't burn gaskets or warp.

Re: Manifold Gland Rings
Don't misunderstand. I wasn't offended or meant any offence. Just asking for clarification on your statements.
