Gland rings
Some people don't use gland rings anymore. I have always tried to use them if I could make them work on a used manifold. I was wondering if anyone could tell me what the right depth of counter bore is for the gland ring to fit in on the engine block. Do the rings fit loose in between the manifold and the engine block when tightened or do they crimp, or do they exactly fit? I'm building a new Burtz engine and they're not machined for gland rings. I'm putting a new manifold on and what is everyone's thoughts on machining this into the block to keep from warping it.

Re: Gland rings
They don't crimp unless the groove in the block still has carbon in it. But I know you are wondering about the burtz block. I always try to use the rings. I was a little disappointed that the burtz block was not counter bored for the rings. I seriously considered doing it but in the end let it slide. I also am using a new exhaust manifold with no leaks at this time. As to the rings I just purchased I think they are crap. Too loose because the strip of metal was cut too short before making it round.

Re: Gland rings
Spread the rings at the gap, squeeze the ring when installing, thusly holding in place. If your rings aren’t springy buy new ones ! As for your new block’s not having bores for rings………call Terry at Burtz

Re: Gland rings
In always use them and keep a few sets on hand. They keep the exhaust manifold from sagging from heat over time.

Re: Gland rings
I don't use the gland rings. If my manifold ends up warping because of it, it means I've had many, many miles of fun to make that happen.

Re: Gland rings
The gland rings I got are dead soft and too short leave an 1/8" gap, useless. They do help with less than perfect manifold. I don't know about keeping a manifold from sagging but If i can only get the rear one in that is what I would do. I bought an otwell health heater for my 29 Briggs and it fits on the block perfect with all four rings.

Re: Gland rings
Whether you think the original purpose of the gland rings was purely to seal the gasket away from the exhaust gases, or also to assist with indexing the manifold on installation, or also to prevent manifold warping, in any of those three cases the rings must be snug to the counterbore, with almost no gap in the ring, in order to be any help.

Re: Gland rings
I found my gland rings in side my exhaust pipe.

Re: Gland rings
In operation, the gland rings expand diametrically to fill the counter-bores, so make sure you have a gap when fitting them at room temperature. It has been my experience that the gland ring at the back manifold port has little to no ability to prevent the exhaust manifold from eventually sagging.

Re: Gland rings
Yeah, there’s a reason that, when Ford discovered the manifold warp problem in ‘31, they didn’t say “make sure you use those gland rings,” they changed the manifold design.

Re: Gland rings
The manifold support bolts are only one of the support system holding features. The other is the exhaust pipe clamp in the rear of the system. Ford really should have used another support closer to the manifold. All that pipe & muffler weight has a forward CG moment that hangs a good portion of the total weight off the manifold. It doesn't seem like lot but it's enough to have an affect after many heat up and cool down cycles.
If a person installs the stainless pipe & muffler assembly then it has even more weight hanging on there. |
