Manifold question

Was a cold but good day today. Put new gaskets on the carb, the new coil arrived from YT, and I installed a new manifold on my 1947 8N w/front dist. Had one surprise.

When I removed the nuts from the old manifold, three were nuts only. The 4th was a bolt with two lock washers. The surprise was that WATER / ANTIFREEZE came pouring out of the hole in the block!

Should I have expected fluid to come out of that 4th hole? It is the hole nearest the radiator. I think it emptied the amount of fluid contained in the upper radiator hose.

Any thoughts (hoping for no bad news)!

When I changed my manifold,

I took the bolts out, if the nuts were stuck to the
bolts, took the nuts off on the bolts that stayed in
the head.

I cleaned the threads good, bought new nuts for all
studs. Put plenty of sealer around those studs that
leaked coolant.

Be sure the head and manifold mating surface are
clean before you put it backed together.

Take your time and be sure you know the proper
torque numbers as you put the tractor back together.
 
Nothing jerks my chain more than someone recommending
a "good", whatever. It begs the question, What
is/are the good ones, what are the bad ones? If you
mean just, "apply a sealer...", then why do not
people just say so? Are there "bad" thread sealers?

How about suggesting "a suitable sealer" instead. And yes - that implies there are unsuitable sealers in that application. I'm sure we could get a lively debate going as to which ones are and are not "suitable" ;-)

TOH
 
that is to say, that if someone says to use a "good" something, that implies that there are some to be avoided. How are we to learn, if they (or the good ones), are not posted. If you mean "any" just say so please and drop the superfluous, "good".
 
Permatex high temp Red sealant is one of my favorite and Permatex Ultra Grey.Two of the best I know about,.Everyone will have preferences..I know these two have never let me down..
 
Gunny, before you dig in to far you may want to
read this in the archives both are Bruce (VA).
Date 04-03-2014 Exhaust manifold. 2nd one is 06-
12-2012- 8N exhaust leak. They will be a big
help. The brass nuts- studs- and torque are very
important on this repair

Well, consider yourself jerked!

Every one has their own idea as what is good or bad. When I said good I really meant one that was designed for that application.
 
I think that a lot of folks are just short and
picky about stuff cause of daylight savings and
less daytime as it seems like midnight at 730 pm.
I miss the long daylight and being outside
myself. Just an uneducated guess.
 
I think that the person recommending the "good sealant" is actually complimenting you by assuming you know or will find out what it means, yourself.

If that can't happen then you ask the person who assumed you'd know or research it, what they would recommend.

It's up to me to ask
Nobody owes me their experience or wisdom.
I try to not bite
The hand that feeds me :D

Mr. Geiger was the first to stress a "good" sealant.
then he later gave a great research tip for impatient searchers.

"Good" means a sealant designed for the application."
Perfectly said!

You can always count on the Loctite people in my experience.
 
" Well, consider yourself jerked!

What "thread sealant" is not designed to be a thread
sealant?
 
In this application,the old reliable Indian Head
gasket sealer has always been a good thread sealer.

take the time and go to a auto parts store and check out all the sealants they have, In this case would you use teflontape? I would not! there are thread sealers for fuel, for water.

Like one said, do your own research!
 

Was this the stuff that came in a little brown bottle? I think that it also went by gasket shellac.

I used the stuff when I rebuilt mt first pontiac engine 35 years ago cause dad had it laying around. Stuff was like gorilla glue.
 
I did that today. Went to two stores, and checked out all their sealers. Using common sense, I theorized that the stud has two ends. One is inside the block and has water against it, The other end is dry and hot, being against the manifold. Water boils at 212*, and a coolant needs to be less than 212* to work.

So, I choose a gasket sealer that is good up to 600* +. The manifold probably will be much hotter that 600*, but that is not the end of the stud that is against water. It should seal ok.

After buttoning things up, new coil, new fan belt, sealed stud, new manifold with stud bolts tightened to 50 ft pounds, I started her up and graded a road. NO LEAKS! She purred like a kitten!

Thank you ALL for your comments & suggestions! Hope I didn't Pi** anyone off, if I did, my apologies in advance.

What is the boiling point of water when it's under pressure?
 
Depends on the pressure. As the pressure goes up, so does the boiling point. How much pressure is in the cooling system of a 8N?

I think I read in a forum somewhere, that water in a 8N is NOT under pressure. True or false?

I believe the 8N's are 4 pounds. That is if you have the correct radiator cap.
 
At 4 pounds of pressure, the boiling point of water is 224.5*. My 600*+ sealer should be just fine.
 
(quoted from post at 17:45:24 11/07/14) Me too--I hate this time -- hadn't had a decent nights sleep since it changed.

What's weird for me is that it seems like it's getting dark a lot more than an hour earlier.

Must be that global warming crap.
 
I agree...I wish it was never changed(like it use to
be).. I really don't see that it accomplishes one
thing by changing it..leave it alone and it
works....
