What happens when a spark plug cracks in the engine? (pic inside)

[DrSzSoLDIeR]

So umm...

im guessing i need a new engine cause i dont think the part that snapped is coming out... :-/

[93Frost_cb7]

damn. if you can't take the head off and shit and get it out then your fucked. h22 time!

[Leung]

how the heck did you do that?

[champagneaccord]

Just use some gorilla glue on it and put it back on, good as new...

jk... looks like someone has to take their head to a machine shop... that's what i'd do.

This just happend to me except for mine broke on the white ceramic part. Luckily it did because all I had to do was unsrew it like normal. It scared the hell out of though. I thought I was going to have to buy a new engine or spend alot of money repairing the one I have.

A lesson for next time....


Lack of this ^^^ and/or over tightening can/will endup with what just happened to you.

[jaymck7]

Man, ur screwed. Taking it to the shop is your best bet or get another engine.

Extractor time.

Can you provide pictures of what the engine looks like with the spark plug piece?

I would say weld a piece of metal so you have something to grip and loosen that S.O.B.

If you can find some Schaeffer's Penetro 90 ( http://www.schaefferoil.com/specialty/190_Penetro.html ) to spray it down with and the a spiral type easy out you should be able to get the broken piece of plug out . The Schaeffer Penetro 90 is a penetrating oil that works better than PB Blaster or WD40 . It was recommended to me by a guy that works at a shop the sells Schaeffer products when I was taking the suspension off my Accord . I had to cut the bolts on the lower trailing arms and didn't want to have to do the same at the junk yard with the rear disk stuff I was buying . I sprayed all the bolts on the car when I got to the junk yard and let them sit while I took the harness and the 5 speed stuff off . When I started taking off the rear disk stuff every bolt came out with just a wrench and 1/2 in drive ratchet . After the bolts were out I could see the dissolved rust on them . I have no doubt that they wouldn't have come out without the Schaeffer's . I have since used it on exhaust bolts/studs , rusted bearings and to loosen up seized cables . I haven't used it on anything that didn't come loose . It's costly and hard to find , but saves allot in the long run . Make sure that none of the porcelain drops down into the cylinder because it will scratch the cylinder walls and cause the rings to by-pass .

the cylindrical hollow threaded part is still in there.

idea #1 (cheap)

take one of your existing plugs and rip it apart so you can measure the internal diameter of that hollow part, then take bolt of the right diameter and carefully slather it with jb weld and stuff it in the one that's still stuck in the engine. Do a test run on the one that's out of the engine to make sure JB weld doesn't scooge all over the place when you do this. See how the JB weld behaves, then if it looks safe do it on the one in the engine.

Spray the inside of the stuck spark plug part with brake cleaner first to get as much oil as possible off of it for good bonding. (don't get any on the head, and don't drip any in the engine for gods sake) just put enough pb to stick the rod into that cylinder part) Now let it sit for one whole day or however long jb weld takes to set full strength.

now take an extension and socket of the right size and take the bolt, and the attached hollow cylindrical part of that spark plug, out of your car.

Then jump around ecstatically holding it up in the air and singing like a madman.

Spray some pb blast and some squirts of motor oil into the cylinder you got brake cleaner in to relube it before starting the car again.

Idea #2

take one of those wall anchors that you use to put things in drywall and put it in the spark plug hole and tighten it till the metal arms press out against the hollow cylinder of the dead spark plug. Grab against it with vise grips and rotate it counterclockwise, it may hold strong enough against it to rotate it out.

personally I like idea #1 better.

idea # 3

lik dksix suggested, use a spiral type ez out. the danger here is you eat thru though spark plug section and into the spark plug threads. Again, do a dry run with a spark plug section that's out of the car, and see how it goes.

Also, whichever methods you use, use a penetrating oil first to loosen the grip on the threads. Then clean the inside surface with brake cleaner, being very careful not to wash dirt and crap into the cylinder. This danger is perhaps one reason that using a screw extractor might be a better idea, because you can do that without cleaning the inside surface of the broken off spark plug part with brake cleaner.

good luck, ingenuity will get that thing out.

edit: someone suggested gorilla glue. I hear that that stuff expands as it cures. If it bonds metal, then gorilla glue instead of jb weld might work to bond a bolt to the inside of that spark plug section. Again, test first, then do it on the car.

id imagine since you have an available bore hole in the center, you could use a properly sized screw extractor on a long extension and just unscrew the threaded part.

[batever]

Before you start messing with it, plug the spark plug hole up and clean the spark plug hole as clean as possible, maybe by using compressed air.

X2 no biggie
