Spark plug thread broke off while trying to get it out!

Was trying to put new spark plugs in motor. When pulling out old spark plugs one of them was stuck and was very hard to unscrew! Put a little more effort into it and then it broke in half leaving the thread stuck in the cylinder head!

What can i do to fix this problem? any advise is welcome!

I did this today, if you are lucky like i was, the core of the plug came out, just leaving the thredas screwed in.if this is the case, just get a stud extractor (the type you screw in bacwards)
that pulled mine straight out, with no issues.

Their are three options;  A tap of the proper size may clean up the existing threads. The second , is a kit called a Heli-Coil where you remove all the threads , tap it out bigger and instal a Heli-coil to bring the threads back to the original size.  The third is to tap it to the biggers size and then look for an oversized plug. I was able to do this for a lawnmower many years ago and do not know if oversized plugs are still available.

On my 97 Saturn sc2 I changed plug wires and #3 spark plug. Had trouble getting plug to seat correctly and now it runs really rough. What could be wrong?

There may be something wrong with the new plug so I would first try a new plug other than the first new plug that you tried. Baring that you may have bad or damaged threads in the head so in that case the head may need pulled and put in a shop that a professional can fix.

Spark plug broke off in head off 5.4 triton motor can get ez out down to it think of removing head

Try using an eazy- out first . If the plug thread has jammed causing it to break then the problem may be carbon build up in plug threads (wrong length plugs used) In which case you will need to pull the head as the thread in the head will be damaged and you will need to fit a thread insert to get it back to normal size.

Spark plug blew out

Did it come unscrewed or did the threads pull out of the head? If the threads pulled out then there are repair kits that will allow you to repair the hole without pulling the head. If you are not comfortable trying this then many repair shops or machine shops will do it. If the plug came unscrewed then rent a thread chaser, clean the threads and put a new plug back in.

Cant find the spark plugs

Its a hemi head motor remove the plastic plate on the top of the head by removing the 10 mm bolts. Be careful you do not lose them or the grommets under them. The plug wires pull up out of the spark plug well down about 4 in. are the plugs. The easy way to get them out is with a socket that has a rubber insert to hold the plug as you lift it out. Be very careful when putting the new plugs in. They cross thread very easily make absolutely sure they are straight before putting the ratchet on the extension and tightening them. Turn the 6'' or so extension by had till they start into the threads. Be sure and dab a little anti seize on the threads to make the job easier and keep the threads in the head where they belong.

Motor has been sitting for a while changed out old gas put new in drained carb bowl put new spark plug wont stay running

Here is the long answer with everything we learned while using a power washer twice a week for years::

It sounds like could be one of the problems listed below or a combination of those things.
1) The exhaust is partially blocked. Check the screen covering exhaust port for carbon and dirt build-up. High-speed exhaust air must pass freely. We finally broke the exhaust screen out with a screwdriver to get our machine going one day.
2) Gas is not flowing freely to carburetor > under gas tank, find the rubber hose connected to carburetor. Pull off rubber hose and make sure gas flows freely. You can use this hose to drain gas tank of old gas ... and then put in fresh gas.
3) Carburetor is partially gummed up and engine cuts off when gas flow slows down. Buy some gum out, and then don't store power washer with gasoline in the tank. Or put additive in gas when storing machine.
4) The choke is letting in too much gas or not enough gas. Try different adjustments. The choke-lever on our power washer got so bad that we could not set throttle at full open or the machine would die. We still use the machine at 2/3 throttle, and then start it each time using WD-40 as described below.
5) Dirty air filter that won't let engine breath enough air to keep up with combustion. Take off air filter and see if problem persists.
6) The spark coil is going bad?? Change spark plug to see if problem persists. Is spark plug wire pushed all the way onto the spark plug?

Now the nitty gritty: we're gonna start that thing right now
7) Take off air filter. Spray WD-40 directly into carburetor. Yes, we use WD-40 every time to start my power washer, and we use the washer twice a week.
Spray in the WD-40, Pull the engine cord. The engine will fire on WD-40. Guaranteed.
Once it starts, keep spraying WD-40 directly into carburetor to keep engine going.
If engine will not fire and keep going on WD-40, then your spark is suspect.
If your engine fires and runs on WD-40 but dies without it, then your gas supply or carburetor are suspect
8) Carburetor problem >>> try Gum out >>> and then take machine to small engine repair shop
9) Spark ... take out spark plug. Put spark wire back on. Hold spark plug by spark wire. Touch metal threads of spark plug to metal opening where plug came out. Metal to metal. Pull back start cord and look for spark between the metal.
If you have no spark, then spark coil is bad >>> take machine to small engine repair shop

My 5700 watt 11 HP McCullough generator wont start. I'm getting good gas to the plug but no spark.

The spark coil is bad if you have no spark

Small engine repair. Part is expensive.

Have you checked spark for sure?
1) Spray WD-40 directly into carburetor
If machine has spark, it will fire
2) Is exhaust port clogged with carbon and dirt?
3) Get new spark plug
Pull out old spark plug
Put spark wire on plug
Hold spark plug wire with fingers
Put spark plug threads against metal opening where spark plug came out.
Metal to metal
Pull cord or push starter
Look for spark between metal

No spark, then spark coil is bad.

Broke off spark plug

A REALLY good engine mechanic can get the plug out, without removing the head; but he REALLY needs to be a really good tech.

What he needs to do is drill out the old plug, increase the size of the spark plug thread hole, and the insert as "heli-coil" to remake the original threads up. The rub here is that when he drills tout the old plug, metal particles will get into the piston area... Only a really good tech can bypass this. If you can't find a guy, the head will have to be pulled.
