I have a broken sparkplug thread in the head of my car and can't start the car now.
I just wanted to know if there was anyone out there that has had this problem and was able to fix it without removing the head.

If so how did you do it and did you vacuum any debris left behind from the spark plug threads?

 

E-Z Out removes the broken piece.

 

Whats that it sounds familiar but I can't picture it. I will do that in seven minutes just tell me how brotha.

 

EZ Out is one brand of broken screw extractor. Drill a hole, tap the extractor in, & use a T-handle to back it out.

Maybe the part that's broken off already has a hole in it, depending on where the plug actually broke.

I'd try as best I can to vacuum out any debris.

 

Yeah it aalready has a hole I'm getting that tool today. And a vacuum extension so that I may be able to reach the top of the piston.

Yeah I will try that too. I used the tool yesterday and got some out. But it seems like half of the threaded part fell in there.

I used the magnetic tool and came up empty. I went to start the car and heard something in there so I will try one last time to clean it up. If not I will just have to take the head off.

 

yikes i hope you didnt get the metal threaded piece from the plug smashed between the piston and head too many times

 

if it was me with this problem id take the head off and do a cleaning job in the cylinder and inspect the plugs threds and such, just cause breaking a plug off in the head is a serious thing!

 

i would also run a tap to chase the threads in the head to eliminate another problem

 

Yeah I decided I'm going to take the head off. I am not going to take a short cut I have to much money and time invested to be cut short.

 

I took the head off and sure enough the whole threaded piece was in there and even scratched up the top off the piston and the left an imprint on one valve. I need new spark plugs now. I hope I didn't f#ck nothin up. Its all back together and ready to run. The weather sucks out here in Boston so I had to do it in the rain.

 

My uneducated guess is... In order to leave an imprint on the valve, it had to hit pretty hard. Check carefully for a bent valve, before re-assembling.

 

You probably alreasy know but so far that valve is strong I guess it's a good thing I have stainless
