Broken Spark Plug at the threads.

HELP! I was checking the hotter Autolite spark plugs that I recently put in. I put down the plug next to the old fouled NGK plugs (Yeah, I still have them). When I put the plug back in, I put in the old NGK, it did not want to go in right, so I took it out and put it in again. I broke the plug below the "nut" where the socket attaches and only the threads are in the engine.

Is there a tool to remove that part of the plug? I tried finding a screwdriver with the right width to wedge in there to remove it, but they have been too long to get any leverage. (At least it was the old plug and not the good new one.)

 

Wow!

What about a stripped screw remover? Is the only thing exposed ceramic? If so, then a stripped screw remover won't work...

BTW... Whatever you, be careful not to knock any ceramic down into the cylinder. It will chew through the walls!

Is there any way you can get needle nose pliers to grab something and twist? If the ceramic is intact, this would be the way to go. Just be careful not to crack the ceramic, because that would cause problems too.

 

I agree with Richard, Wow!
So what is left above the threaded sparkplug hole? Is it a hollow ring with the threads on it or is some of the center electrode and ceramic left?
If a hollow ring is left, a drill bit slightly larger than the inside diameter could be reverse turned in "by hand" and the loose threaded piece removed. At least it shoud be loose with the nut part broken off. If some of the ceramic is left a wooden or plastic rod could be glued to the remaining piece and then turned out. Best way to do that is with cyanoacrylate ( superglue) and acetone. Yo won't have much success drilling into ceramic. Place cyanoacrylate on the end of the plastic rod and drop acetone on it as soon as it sits on the remaining piece like you want. The acetone will make the cyanoacrylate set almost instantly. Keeping it from getting on the threads. Or you could use a reverse drill bit on the center electrode.
The piston can be rotated to TDC to and therefore minimize any damage if foreign matter gets in. Once the part is out a plastic straw can be taped to a shop vac and inserted into the cylinder to clean out foreign matter.

 

It is the hollow metal threads only. All of the ceramic came out intact. I will try these tonight.

 

If you don't have a "Screw Extractor" or an "Easy-Out" to bring those threads out ... you can fabricate a tool to fit in there "Snuggly" to bring those threads out. You need to grind sharp "Cutting-edges" on the tool you make ... to "Grab" the inside diameter of the threads ... which should NOT be under a torqued-load and NOT resist coming out.

The Vacuum method is a good idea. I'd add this to using the Vacuum. Use the home Vacuum cleaner. The ShopVac will collapse the straws. Stop-by 7-11 and grab a dozen of the long "Slurpie" straws. Place two (2) straws ... side by side. One to attach to the vacuum hose ... the other one NOT attached to the Vacuum ... but, used as a "Vent" to allow the vacuum to be effective at the end of the straw hooked-up to the cleaner.

The second straw will help draw air toward the straw hooked-up ... instead of drawing air through the sparkplug hole ... which will cause turbulence and allow the fragments to escape being sucked-out.

If you get into a situation where the vacuum doesn't get all the fragments ... get a ball of twine and grease the twine as you push the Loooong -- never-ending -- length of twine in there.

Then, ... have good light ... needle-nose and tweezers ... handy as you draw the twine back out. Pick-out any pieces you think might fall-off before being pulled-out of the sparkplug hole.

 

I DID IT! I finally got the threads out. I found a small wood chisel that would fit inside of the threads. The sharp end bit into the metal and let me screw it out. I tried an easy out, but they are too short to fit in the hole.

Riding resumes TODAY!

 

Chalk-up another one for "The Old School Method"

Now, tune-up that baby 'til it's on the racers edge of performance ... and, go out and get yourself a big, fat speeding ticket.

 

Bravo and good show!!! Just goes to show thinking outside the box can save the day!

 

"Is sarr rite?"

"Sarr rite!"

"Is OK?"

"So-kay ... shud duh box!" : )

Who's old enough to remember where you heard that before???

 

I don't think I should say but thanks Quickdraw!

 

I remember a certain margarine commercial... I'm hoping that this doesn't date me!

 

Ed Sulivan, can't remember the guy who did that act, but was always funny to watch!

 

Bingo!!!

We have a winner!

The ventriloquist "Senior Wensis" ... a very funny Ventriloquist who regularly appeared on the Ed Sullivan Show. Not just funny -- but, great; too!

(He'd let the dummy tell somewhat of a long joke ... and, while he was listening to the dummy ... he'd light and smoke a cigarette!)

Goodnight; Gracie

Monday starts Ventriloquist Week back at The Ed Sullivan Theater. David Letterman is having a quest ventriloquist each night!

 

Blackhammer , do you "noemally" bench press 300lbs and on a good day 400? , take it easy on the spanners....
