#1: Exhaust manifold no longer made- option?

Posted on 2008-03-04 06:46:31 by Bubba

I've found it nearly impossible to find an exhaust
manifold for my '79 Ford Granada with the
250 ci six. Mine is cracked in two.

No major auto parts stores carry it and Ford says
it's no longer made.

I've searched every junkyard in a 75 mile radius.

What are my options? I've heard they don't weld
up too well. I've heard of "brazing". Does this
work?

Thanks for any help....

You can get a used manifold for about

These things CAN be welded too, it's just the welder needs to build a little
jig to hold everything in position while it's being welded, which makes it
a more expensive job to do right. Then it needs to be re-annealed after
welding or it will crack at the weld.

I'd be a little wary of brazing something that gets that hot, but the braze
will be much less brittle than a rough weld.

And you can't find a fox bodied ford with a 200 or 250? crappy yards.

If I remember correctly there is no exhaust manifold difference between
the 200 and 250. The only thing is that later versions like yours have
the tubes for the air pump while earlier versions do not.

What part of it broke? The actual casting or one of the air pump tubes?

Maybe someone local to you can help you find one, try
<a href="http://www.fordsix.com/" target="_blank">http://www.fordsix.com/</a> in the forums.... Or you could just buy a header
for it ;)

Regarding the lack of Fox bodies, and older cars in general in salvage
yards.... I am the office manager of a salvage yard, and it is a shame
that the older stuff is just being crushed. But with the price of scrap
metal being at record highs, the yards don't have much choice. If the
yard pays $180 per ton, as is the local price now, a 2 ton car or truck
brings the scrapper $360. Now, the yard can sit on the vehicle, hoping
to maybe sell a couple of parts off it, or strip and crush it. We rip
out the motor/trans, which can be scrapped or sold to core buyers for
nearly as much as we could get by selling to a customer. ( which also
entails more time to pull gently, and a warranty that must be honored )
We can process the car in less than half an hour. With so much money
tied up in an old clunker, that may or may not ever sell a part, when it
can be turned into scrap doesn't make sense to keep around. Also, the
aftermarket is producing more and more items, many of which sell for the
same as we would have to charge to pay the yard guys to pull off the
cars for the customer. As a car guy, and a circletrack racer, it makes
me sick to see what gets crushed, but I know it must be done. I
pesonally think that there will be alot of regret in 10 years by
everyone that so much was crushed, but as long as the price of scrap
stays so high, crushing will continue, and many parts will have to be
bought new or not at all. Big E

Thanks for the leads and help.

Through Car-parts I found one 58 miles away but
the guy said it was very warped, almost 1/2&quot;.
Buying from an out-of-state junkyard is a last-resort
for me... not everyone is honest and I'll need lots
of luck to get one shipped that is crack free and
straight. I'd really like to see it in person, even
if I have to travel.

The new header option is a good possibility.
I called 'classic inlines' today and left a detailed
message (as they said) but never heard back
from them. I will see it there are others who
could provide a header for this motor.
According to the header websites, the 200 ci
and 250 ci are not compatable, I think because
of the starter location. I have the original A/C
so that will be a problem too maybe as they say
it will have to be re-routed.

As the last poster said, it's a shame so many of
these old cars are trashed, but I understand.
Wish they'd pull the exhaust manifolds off first :)

Thanks again and I will pursue these leads.

In the old days, people used to cut out templates and weld up their own
headers.
It can still be done if you are clever with cutting and welding equipment.

I plan to go to my local pick and pull on Saturday. We still have a

Thank you for the kind offer to look for me.
Using a nationwide search with CarParts.com I found
a NEW original equipment one. The guy claims it's
brand new so I bought it today and it's coming UPS.
I will post here when I get it.
Thanks again to all. These forums are extremely

Got the new exhaust manifold and yes, it
is NEW! I just can't believe it. The holes
match a gasket I have so it should work.

I have a question though.....
It has port holes in each exhaust port,
they look like spark plug holes, about the
same size and threaded. Must be for some
pollution control stuff, which I don't have.
How do I plug these? I could come up
with my own ideas but there must be a
correct way.

THANK YOU to all for helping me find
an exhaust manifold. It was really wearing

Your '79 should have an air pump or at least it did from the factory.
That's what I was asking you about earlier, the tubes that go into the
manifold for the air pump.

I'll guess it's just an NPT thread and you could probably just use a
cast iron threaded plug from the plumbing isle... just put some high
temp anti-seize on it first so if you ever need to remove them they'll
come out.

thinking about it some more, maybe a thin coating of high-temp
red exhaust mainfold RTV might be better than anti-sieze to just to
prevent an exhaust leak.

maybe someone else will have a better idea....

Maybe, or they might be flare fittings. In either case plugs should
be available, although flare plugs will be a little harder to find.
I'd use brass rather than cast iron, but that's just my prejudice,
either should work.

Go to an industrial bolt supplier. Get some bolts that fit the holes.
Grind them down so that they don't protrude into the manifolt at all,
but are more or less flush inside.

The existing cast iron manifold doesn't have these threaded holes,
it's cast without them. There's no sign of an air pump or brackets
for one. I guess if there was one, it's long gone.

I looked quite a while for a correct bolt today. It's the same
thread as the spark plugs on my Yamaha 650- BP7ES.
It's like a 9/16th with a fine #18 thread. I don't want to use
spark plugs because everything looks so good and original,
so I'll keep looking.

Somebody modified something I would guess. The thermactor(sp?) system
(the air pump) was added in ~1975 and as far as I know was present on
the 6cylinder for the rest of its run (to ~1984). I haven't seen a 75 or
later one in a junk yard that didn't have it. Either someone removed
it and replaced the manifold with an earlier one or swapped the engine
for an earlier one. Sadly, my 1978 shop manual does not have a picture
of the exhaust manifold side of the engine.

&gt; &gt; &gt;I have a question though.....
&gt; &gt; &gt;It has port holes in each exhaust port,
&gt; &gt; &gt;they look like spark plug holes, about the
&gt; &gt; &gt;same size and threaded. =A0Must be for some
&gt; &gt; &gt;pollution control stuff, which I don't have.
&gt; &gt; &gt;How do I plug these? =A0I could come up
&gt; &gt; &gt;with my own ideas but there must be a
&gt; &gt; &gt;correct way.
&gt;
&gt; &gt; &gt;THANK YOU to all for helping me find
&gt; &gt; &gt;an exhaust manifold. =A0It was really wearing
&gt; &gt; &gt;me down.
&gt;
&gt; &gt; Your '79 should have an air pump or at least it did from the factory.
&gt; &gt; That's what I was asking you about earlier, the tubes that go into the
&gt; &gt; manifold for the air pump.
&gt;
&gt; The existing cast iron manifold doesn't have these threaded holes,
&gt; it's cast without them. =A0There's no sign of an air pump or brackets
&gt; for one. =A0I guess if there was one, it's long gone.
&gt;
&gt; &gt; I'll guess it's just an NPT thread and you could probably just use a
&gt; &gt; cast iron threaded plug from the plumbing isle...
&gt;
&gt; I looked quite a while for a correct bolt today. =A0It's the same
&gt; thread as the spark plugs on my Yamaha 650- BP7ES.
&gt; It's like a 9/16th with a fine #18 thread. =A0 I don't want to use
&gt; spark plugs because everything looks so good and original,
&gt; so I'll keep looking.

it's probably either a 14mm or 18mm thread. since you say &quot;9/16&quot;
sounds like 14mm (1/2&quot; is appx. 12.7 mm)

Chances are it is original.
While I am not at all familiar with Ford products, I do know that back in
that era 49 state trucks over about 6000 pounds GVW were exempt from
emission controls, and were designed to be operated on leaded or unleaded
fuel.

So while I can see someone going to the trouble to remove an air pump and
all it's plumbing, I cannot see them going to the additional trouble and
expense of changing out the entire exhaust manifold.

I purchased a new 1978 GMC heavy half ton pickup with a 350 gas engine that
has no emission controls at all. No air pump, no catalytic conv., no EGR.
It does have a preheat air cleaner and a coolant temperature switch for the
distributor vacuum advance.

&gt;
&gt; Somebody modified something I would guess. The thermactor(sp?) system
&gt; (the air pump) was added in ~1975 and as far as I know was present on
&gt; the 6cylinder for the rest of its run (to ~1984). I haven't seen a 75 or
&gt; later one in a junk yard that didn't have it. Either someone removed
&gt; it and replaced the manifold with an earlier one or swapped the engine
&gt; for an earlier one. Sadly, my 1978 shop manual does not have a picture
&gt; of the exhaust manifold side of the engine.

Please disregard my reply, I forgot he was working on a car and not a truck.

He's driving a '79 fairmont with a 250cid 6. Ford truck sixes are the
230 and 300 and a different engine family.

The '78 fairmont my parents had, had an airpump. The '82? mustang the
neighbor kid had, had an airpump. Every '75 and up ford small six I've
seen in the junkyard has had an airpump. My '75 maverick with a 200cid 6
had an airpump. My'73 maverick does not have an airpump, the change was
in 74 or 75. The picture in the '78 shop manual shows the airpump, but
it's a picture from the driver's side so only the pump itself is
visible.

&gt;So while I can see someone going to the trouble to remove an air pump and
&gt;all it's plumbing, I cannot see them going to the additional trouble and
&gt;expense of changing out the entire exhaust manifold.

If you have an old manifold laying around it's cheaper and maybe
even easier than screwing around with plugging the lines. Having worked
on these engines with and without the thermactor system, removing it
entirely and replacing the manifold is the best solution. The damn
thing is always in the way. It blocks access to the front and much
of both sides of the engine.

What I have is a '79 Granada 250ci.
I should have mentioned that the new OEM exhaust
manifold is tagged to be for a '75 Granada 250ci.
It's official part # is D5DE-9430-CA.
I wonder if the CA means california version which
seems to me would have a higher emissions standard.

CA is just the revison as I recall... Ford doesn't change the year on
the part number unless the part actually changes, so it would carry D5
in '79 if it didn't change.

I finally plugged the manifold ports because I'm
installing it tomorrow.

The best I could find to plug the emissions holes
were tractor wheel lug bolts at Tractor Supply.
They were too long so I cut them shorter.
The threads were a hair off. After 3/8&quot; of
screwing in they would start to cross thread.
I cut them to 1/2&quot; long and tightened them in until
they bottomed out agains the tapered head.
I used high temp threadlock also and they are
very tight and seated well.

The farthest hole to the back was different.
My old manifold has this one emissions port
which is jury-rigged plugged.
I found that a standard cast iron pipe plug
fit this very coarse thread perfectly and
I installed it into the new manifold as above.
I don't know how they'll ever come out,
but with my luck they will.

Thanks again for all the great advice. I still
can't believe I found a brand new manifold
using the recommended links.

Bubba.
