Is there a hi-temp expanding foam on the market?
Is there a hi-temp expanding foam on the market?
Hello,
I have a small hole in the exhaust manifold right where it attaches to the
engine -- actually a small piece of the gasket is missing. There's a little
space in there that would seem ideally suited to accept a dollop of foam.
The foaming insulation at the hardware store can only deal with temps below
200 degrees. Is there anything out there with a higher temp rating?
(JB Weld works okay, but doesn't seem to last)
Thanks!!!!
Fred

Anything but replacing the gasket will be short-term.

What Brent said. If the manifold is warped it should be surfaced, or
if you're chea^H^H^H^Hfrugal I have heard of people using fine solid
copper wire to "o-ring" the gaskets.

No. A foam would not work well over a wide temperature range, because the
gas inside the bubbles would expand and contract a lot.
You might consider red RTV, but really the solution is to replace the gasket
and do it right.

Unfortunately, everything is so rusted that it would be a massive
undertaking to do it right. Not worth it to me.
I may try the red RTV though. Thanks!

If it's severely rusted, any filler you put on is going to adhere only
to the rust, not to the metal underneath. And the rust is not a solid
substrate and will not hold it on very well.
That is part of why the JB Weld is not working.

Start soaking the hardware with penetrating oil now (NOT WD-40) and
invest in a MAPP torch (or oxyacetylene, if you think you might be
doing this a lot.) also some 6 point sockets and bolt-outs if you
don't have them.
Is the manifold held on by studs or bolts? If studs, run a die down
the threads before you try to remove the nuts. Use the die
"backwards" so it cleans the threads right down to the nuts. If the
mfgr. of your vehicle was throughtful, they used copper or brass nuts
which will burn right off with a hot enough torch without damaging the
studs.

the only way anything will hold is to get it into the crack. JB weld
will be your best bet, if you can get a vaccume in the exaust using a
vacume cleaner or better a vaccume pump and pull the stuff into the
crack using the internal vaccume. anything else is a waste of time.

Furnace cement ought to work. Get it from a place that sells wood stoves. Follow
the instructions for filling cracks. Give it a full day to dry. You have to make
sure you get all the moisture out before you get the temp above boiling or it
will crack.

Yes I hesitated to offer the advice because it probably won't work if not
done correctly. Furnace cement will definitely take the heat - a lot more
heat than a car exhaust usually gets. And it expands at the same rate as
iron so heat and expansion aren't a problem even if you get the exhaust
cherry red.
It won't work on tin exhaust parts that flex but for filling a crack
where it is rigid and there is no flex it shouldn't be a problem. Of
course there is a bit of skill to applying it correctly so that it adheres
and locks itself in. It won't work on furnaces and stoves either when not
applied correctly.

I think I'll try this next ... if there is a "next" . I JB welded it a few
days ago ... maybe it will hold more than a few months. I don't drive that
much.
And by the way, the car is a 1983 VW Rabbit GTI. And the rust problem is
limited to the nuts and bolts - the manifold seems to be fine. The nuts are
starting to look like something off of an excavated sea wreck. I don't think
I have the tools or patience to do it right.
Thanks again for all of the help!!!

Re: Is there a hi-temp expanding foam on the market?
HEAT is the fastest way to attack those nuts.
Sears sells some "rounded-nut" sockets that should work for you.
If you remove the intake manifold, that should give you more room to do it
above the engine. ;-)
Some shops can do this for you and they won't charge that much.
I personally like the studs replaced if they are too horrible. And install
new brass self-locking nuts. <g>

HEAT is the fastest way to attack those nuts.
Sears sells some "rounded-nut" sockets that should work for you.
If you remove the intake manifold, that should give you more room to do it
above the engine. ;-)
Some shops can do this for you and they won't charge that much.
I personally like the studs replaced if they are too horrible. And install
new brass self-locking nuts. <g>
