Wow.

That's going to be a bitch.

I would highly suggest taking it to a mechanic who specializes in Honda engine rebuilds.

There are a couple of ways to tackle the problem, none of which I would ever attempt. I have heard of people using EZ outs and reverse thread drill bits on busted manifold bolts, but never a spark plug. The problem with the EZ outs is the possibility of breaking one off, then you have an even bigger problem.

The other way I've heard of dealing with this is to weld a new nut on top of the busted bolt. In this case, that would require, at a minimum, the head removed.

Good luck, keep us posted, and remember to use anti-seize compound on your new set of plugs.

 

^Drill it out, remove your cat and watch all that stuff fly out your header (haha this would be so bad).

I guess you could try that bolt-out that sears carries.

 

Take it to the mechanic that did it and tell him it's his problem. I don't see where there is any grey area here.

 

I would do as fjm said, take it to a Reputable shop who's worked on many honda's. There's other things you can try, but they all have risks. Unless you can get ahold of one of these sockets:


Why kind of mechanic leaves you in such a situation???

Keep track of everything you spend getting that plug fixed, and bill him. I would hold him completely liable, especially if he offered no compensation in the beginning. Good Luck!

 

Wow that sucks...

 

From the pics, it looks like the part of the plug with the nut is loose and detached from the thread (?) Heard of that happening on very old cars, never actually seen pics.

I can't tell if that is the electrode with the tip of the plug that is sticking out. If so, there would be a small hole into the cylinder, and the reason why the cap flies around is because the pressure from the cylinder escapes through the hole.

If that is the case I would not drill this out, because particles of ceramic material will end up in the cylinder, and I don't think there is any way to avoid getting them all out and not scoring the cyl. walls. For the same reason, I would not drive it at all.

An easy-out will have nothing but ceramic material to grab onto, so that may not work either.

I think you may have to pull the head, and do it on the bench. Titanium coated drill or a small chisel, then a ez-out or bolt extractor, and even after that you may have to put a sleeve into the spark plug hole because the threads may be damaged.

 

Good luck buddy

 

WTF kind of mechanic breaks something i gives it back to you

 

Based on personal experience, the head is going to have to be removed and a machinist will probably have to drill and retap the threads.
