For years I have wrestled with trying to fit old bent exhaust manifolds to various T's. Today I fitted a new one from Langs on my Fordor. From start to finish the job was done is less than an hour. No more leaks and nice and quiet. The manifold I took off had warped nearly half an inch from end to end. It was one that had previously been straightened by heating and bending on a jig. It seems it has reverted to its old shape?? With the Aussie dollar conversion and international postage the manifold comes to around $150 but still a great investment. I highly recommend it,
I can't agree with you more! Fortunately I can get them closer to home with a bit less shipping, I'm actually only 2 hour drive from Snyders, so once in a while a friend and I make a "road trip" and take our list with us, have a nice excursion, see some nice people, and save the shipping (so to speak, at $4 a gallon?) Anyway, yes, nothing like a new, straight exhaust manifold. And I use those albeit a bit more expensive copper rings with the gland "built into them"...they really work nice.
Also agree. Those new manifolds seem to be top quality and the copper O rings make it even better. I'll save my cost saving repair efforts for other parts of the car.
Hi Warwick, is that your Fordor (now with a new exhaust manifold)for sale recently??

If folks would have used the steel glands like you are supposed to, they wouldn't have warped in the first place!
Larry mine had steel glands and crush rings and it warped. I didn't know it was warped because I didn't have any kind of exhaust leak. But, once I took it off it absolutely refused to go back on. I ended up getting a new one with the one piece copper tube/ring combos. Went right on with no problem and I have no leaks.
These solid copper combo glands are the way to go provided your exhaust manifold is straight. You can take your manifolds off an on as much as you like without having to replace the copper glands. They are a more expensive, but their long life more then makes up for the price.
Those are what I was talking about Jay, those babies are the business. I've had my manifolds on and off a few times and there's been no damage to those. I like how thick and substantial they are.
I recently spent a couple hours struggling with the all copper rings on a new manifold and a freshly machined block that had been re-ported in the machine shop. The rings are very unforgiving if there is the slightest mismatch. All machinists need tolerances to work with and the all copper rings are close enough to an interference fit to create problems. I ended up taking a file to chamfer both sides of the rings to allow the ports in the block and the manifold to start. Once started they went fine.
Jay; I was told those can damage an aluminum intake so I've not tried them, but I have a set. Have you used them with aluminum, iron or both?
New manifolds are the way to go. I put a new one on my rebuilt engine and gave the old one to a blacksmith friend of mine to play with. For around $100, it wasn't worth the aggravation to deal with an old one that didn't fit correctly.
Thanks for sharing your comments on the new manifold and copper all in one gaskets. Hope you at least got the gaskets here. You probably already know they shrink a little with heat, so you need to check and re tighten. I put mine in with a new manifold in 2010 and haven't looked back. I also had file my gaskets like Mike and it took awhile, but it was worth it. Ordered a few more sets as spares.
The Fordor for sale here on the Forums, is mine.
Always good to hear from you Tom! I want to see you on our 2016 Tour , maybe in a Mercury???. I will be testing out the new manifold installation on this weekends 3 day Winter T Club Tour.
Gary, did you ask what the problem was with an aluminium manifold?
I think I would want more than one persons opinion before I dis regarded something like that. Anyone else heard of this one???
I have these with my aluminium manifold, no problems.
Peter, Warwick is in Australia different Fordor.
Gary, The copper works fine with my aluminium intake.
Can anyone give me the outside diameter of the part that goes inside the manifold and block recess? I'd like to see if these will fit my Maxwell.
1 1/4" ........
If you plan on using those handy, dandy, one piece jobbers they would probably do a good job sealing even if the holes in your Maxwell were a sixteenth larger.
Thanks Craig, unfortunately the Maxwell's roughly 1 9/16".
Howard......does the Maxwell use the "tubes" between the manifold and block too?
I have an idea.......maybe........
I used the same old rings with a new gasket and some high temp gasket seal. The front port has a slight leak so I will fit new copper rings after this weekends tour. Ran out of time to fix properly. It seals up after it heats up so will have to do for the weekend. Thanks for all your interest and comments. Still think it is the best money I ever spent on a T part. all my original manifolds are rubbish!
