First of all, WD-40 is not a penetrating oil, claims to the contrary by
the manufacturer and thousands of users notwithstanding. It's a little
late now, but really, you should have used Kroil, PB Blaster, or one of
the other purpose-made penetrating oils rather than WD-40. Guess you
will remember that next time :/

Now as to your immediate situation - that sucker is broken off in a very
difficult way. I would personally suggest, if you have access, dropping
the downpipe so the bottom of the manifold is open, and then trying to
drill it out with successively larger drill bits. If you are lucky the
drill bit will "catch" and spin the remaining piece out into the
manifold (this is why I suggested dropping the downpipe.) If you are
less than lucky, you'll end up drilling it out to the threads, in which
case a spark plug thread chaser tap should clean them up.

You may find it easier to remove the manifold from the car; I haven't
ever worked on a Honda so I don't know how difficult access is vs.
manifold removal.

Needless to say, put some anti-seize on the threads of the new O2
sensor, and next time you go to replace one, before you get to the point
of breakage, try heating the manifold around the sensor with a torch,
pref. oxyacetylene if you have access to one.

good luck,

nate

Liquid Wrench penetrating oil. Soak repeatedly. Then pull all the
garbage out of the center of the O2 sensor that is still in the
manifold, and use an EZ OUT, or just drill the sucker with a large
drill bit until it spins off on its own.

WD 40 is $hit in a can.

Or you can also use a pipe tool that when you turn it counterclockwise,
will grab the inside of whatever is left in there and will come out. I had
a similar problem with my lawn tractor.... the drain pipe for the oil was
way too short and wanted to lenghten it. Well somehow, it broke off right at
the edge of the engine block and I used one of those pipe tools that goes
inside. I got it at home repo (depot) for not too much.

Good Luck,

yeesh. some options, in no particular order-

junkyard manifold
new manifold
new header
take it to a machine shop- let them get it out and rethread it
you drill it out/rethread it
hammer big flathead screwdriver into it, try to turn
judicious use of an air chisel, big flathead, try to turn

Hmm, I've never seen what you're describing, but it sounds like
something to add to the bag o' tricks. Is this a plumbing tool? I will
have to look next time I'm at Home Despot.

PS - I have never had any luck with EZ-outs. They always seem to break
on me.

Excellent idea. LEVERAGE IS YOUR FRIEND. Long handles are in

That's what I had to do with my 40 year old bathtub drain. I had to
make 2 cuts, one on each side, about 120 degrees apart from eachother,
and then the entire affair collapsed in on itself with a little help
from a screwdriver and a hammer.

Because I have to *anneal* mine first, the big ones, by heating with a
propane tourch and then letting them air cool. It takes the
brittleness out of them.

Yes, they are sold at home depot....when i had this problem, i didn't
know what to do either until I went there and started asking around..... one
of the people there showed me it....and told me it works wonders...forgot
how much it is, but I don't think it was too much.... it comes in three
sizes....well the one i have did...

good luck,

I share your frustration. If they grip, they love to break... but often they
just don't bite well enough.

I had a thought, though. The threads are jammed because they have tried to
weld together, with the "pull" direction being the main force. When the
EZ-out is seated, how about a few judicious taps with a hammer (or whatever
will fit in the space available) on the end of the EZ-out to try to weaken
those welds?

That sounds like a good idea, if there is room to get it.

Soak with PB Blaster an hour. Try an EZ-Out, some tapping
(vibrations work wonders, like Michael suggests). EZ-Outs
often fail, but they often work, too. They may be had at
Autozone. Otherwise, what others said.

In my experience, PB Blaster is superior to Liquid Wrench,
by a lot. They are about the same price. PB Blaster worked
great on my exhaust system bolts last year, though the
closer I got to the manifold, the tougher freeing bolts
became.

Updates are welcome. Good luck.

HEAT. Grab a torch (MAPP or propane will work just take a bit longer)
Heat the remaining part and the manifold till it is red hot and then
spray it with some good lube(Kroil, PB Blaster or the like NOT WD40). It
will smoke like crazy. Let it cool and wipe it off. Now heat it again
and drive a tapered square style EZ OUT in good. let it set a bit and
turn it out. should come out easily this way.
