Has anyone has have their spark plug terminal stud broken inside the well before? I caught it early coming from work, oil was dripping out (on to the Lower manifold) and had smoke coming out the exhaust (unburned oil). I looked inside and thought That was was weird. Usually breaks by the electrode or by extracting it. Please educate me, I am looking into my finding of what else happened

.
Camera is broken got it off my laptop.

 

Which engine?

Removing the spark plug for inspection will tell the rest of the tale. I've seen something like this before and it wasn't pretty. I hope this is not the case here.

 

If not 100% sure you can tackle it, get a good mechanic immediately. Unfixed it is damaging the cat. conv.

 

I'm really upset it is turning out to be more then spark plug. I am finding sand and a small spring near the thread, and rest of my spark plug wells. It was before they change the cylinder numbering 1-6 . I'm starting to think someone use a leaf blower near my exhaust when we were cleaning the parking lot (like in the army) not sure. Worried about my pistons, but not concluding to that. Don't know were a small spring came from or the other side. Gotta redo my valve cover gaskets.

 

Get one of them horoscopes such as this and have a look inside the cylinder. It will show you if there is any other damage on the piston etc.

hmmm I need one of those scary. Here is the spring I found.

 

Don't quite follow this.................

 

It's really bad misfire with a broken terminal stud broken on spark plug. I found a spring near the thread making it worse. I'm sure it's not leaf blower incident. Originally tried to see what caused the terminal stud to break, still working on it.

 

Okay guys/gals listen carefully if ever break a terminal off a spark plug. Chances are you might stumble on a small spring (sometimes in other wells). So it is not from the piston chamber. Got to redo my gaskets boring.

 

The small spring is from the inside of the tip of the coil (COP),
Looks like some one was ruff when fitting/removing that plug , the sand I don't know about .mystery
