When replacing he manifolds, do you do it in a particular order - such as intake first or exhaust first? Do you take the exhaust loose from the manifold first? All helpful hints appreciated!
For sure, remove the exhaust pipe and its packing nut from the exhaust manifold first. Then assuming that you don't have a vaporizer setup or an after market one piece intake/exhaust manifold, like a Wilmo, it does matter which manifold is removed first. When replacing them. it is helpful to have more than two hands available, or one of the installation tools that the dealers sell.
I think Terry W. meant "...it [doesn't] matter which manifold is removed first."
When replacing them, you do both at the same time, which is why Terry W. recommends extra hands.
I install the intake first using cut-off or turned clamps to verify good sealing and I only use the original ring & gland sets then I install the exhaust manifold and again, verify that all 4 ports went onto the rings visually.
I was thinking about just what Steve said. Last time I did the exhaust first, and that may be what is causing my issue.
I've installed "dozens" of manifolds for myself & customers - I find it much simpler and easy to visually verify by doing intake first - looking down from the top then the same drill with the exhaust - you can see all the ports going "home" !
Yep, Jerry; I didn't catch my mistake before I posted and once done; its chiseled in stone.
I like to help out those copper rings with a little high-temp RTV, especially if there are any rust pits.
FORD Parts 3063 and 3064. See also page 14 in the 8-5-28 parts book.
AHH! Thanks. If this try doesn't do the job, I will order a set of those!
Don't fool around with anything other than the gaskets that Steve has shown. Just about any other style will allow your manifold to warp.
Some people swear by the copper gaskets which combine the ring and the gasket in one piece. I believe they're an import from Oz. They look to me like they would work as well as the stock items, but I don't see how they would be any better. I've never tried them because they cost nearly four times the price of the correct ones.
I agree that installing the inlet manifold first is a good idea. Indeed if you are lucky enough to have a Chaffin High Volume manifold, it is essential as the larger size make installation of the inlet almost impossible once the exhaust is in place. JMHO
Here's how I do it. Hold the exhaust manifold in place with one hand. Install clamps on studs 1 & 4 in a vertical position. Run two nuts on studs 1 & 4 just hand tight against the two clamps. This will hold the manifold in place. Next, install the intake manifold and place clamps and nuts on studs 2 & 3 in the normal position and snug these up. Now you can back off the nuts on studs 1 & 4 and rotate the clamps into the proper position and snug up those nuts. There you have it. Only requires two hands and no special tools or fixtures. Easy as pie.
Just a reminder, after you have fired up the motor, don't forget to retighten all again. Others will have a schedule when and how many times. Don't let a leak start.
Robert H. - that is almost exactly how I finally did it! I was going to say that i did everything wrong and it worked LOL. I didn't even take the exhaust loose because it was not going to come off easily if at all. I applied RTV liberally to all 6 rings, clamped the intake in place for a while so there was a good seal, then took it off, installed the exhaust as you describe, then the intake and it all works just fine. Great to have it running once again. As always, thanks for all the help! If I ever have to do this again, I will certainly use copper washers.
I install the exhaust manifold first, hold it in place with the end clamps turned vertical then install the intake and rest of clamps. Been doing it that way from day one and works fine for me. Only need two hands.
