I posted pics for another discussion, so might as well spread some weirdness
here too. I didn't have access to a TIG welder at the time, or funds to pay
someone.

I actually JB welded an aluminum cyl head on my Datsun truck. It corroded
as the PO had never changed the coolant, and it undermined the metal ring
under the headgasket, allowing the gasket to blow. The hole didn't actually
enter the combustion chamber. I figured i would junk the truck rather than
buy a head, so i used a spot-blaster to clean the metal, epoxied it and
filed it smooth. It's been 4.5 years and still holding. I wouldn't have
believed it, and would never have tried it on someone else's engine.

You tease us, then offer no 'after' pics?

There are indeed things JB weld does really well.


Dave

I just used it to effect a similar repair on my Escort. Same
issue, coolant not maintained. I was losing coolant, but not
getting any CO in the coolant. (there's a neat chemical test
to check for this, a mechanic friend scoped it out for me)
A dropped valve seat forced the issue, and I found the head
has two large openings on the intake side, the sole purpose
of which appears to be to let the core sand out. These two
spots on the intake manifold had deep corrosion with pits
extending to the #4 hole. Which was clean as a whistle....

I expect the repair to last as long as I own the car.


Jon

What would the world be like without JB weld and duct tape?

No, you glued, not welded.

JB Well-Duh is common epoxy cement with a name for suckers.

Epoxy is a modern miracle. But it is not welding.

He didn'd say he "welded" the head, he said he "JB Welded" the head.
If the stuff was called metal putty he would have said he "metal
puttied" the head.

And even prior to epoxy, there were "wonder putties" that sealed up
cooling leaks very well. Things like IronTite and other "boiler
sealers"repaired many a cracked engine block in years gone by - some
which remained in service for DECADES on the repair.

I agree, it's _glued_ . What I really hate is people trying
to fix something
with jbweld and then bring it in for welding. That stuff
produces the
most hateful fumes known to man, very toxic stuff! And it is
a bitch to
get rid of it all to weld, especially when it has been
pressed into the
crack and extruded on the inside. How about that jbquick,
for those
times when you absolutely do not have the time to do it
right.;)

JB Weld is not for when you don't have time to do it right NOW. It's
for when it's fix it cheap NOW or throw it out - don't plan on fixing
it right later.

So you are willing to throw out an expensive component
because of one
mangled feature that could be easily repaired by welding and
re-machining
if neccessary? I see plenty of that in my work. jbweld
didn't fix that stripped
thread so why is it now on my weld table full of jbweld?
Same for this
crankcase, the jbweld had no chance of adhering to anything
on that
motor oily and hot so why am I dealing with it on my table?
jbweld, like you
say, should be left for use on the junk stuff,
only.......;) A better alternative
would be Devcon Plastic Steel, two part epoxy. It comes in
liquid slow
cure and five minute putty too. Great stuff, makes jbweld
look like the
pigeon sh.t it is. Hey, now that I got started on a rant let
me add teflon
tape (rarely appropriate ) and black plastic electrical tape
( it never stays
on ). Thanks for listening, I feel better now......

Stretch the electrical tape good as you apply, don't stretch the last
wrap. Works for me.

I agree on the teflon tape. Doesn't prevent galling on stainless,
tendrils plug small orifices, etc.

And spend the $ on the good 3M Super 33+, not the $0.49 garbage.
