Come see what I found... 
Come see what I found...
:( ....oh ya FUCKED!!!
How they hell could this of happend? Should I be severly concerned? From what I can tell this could of happend a long time ago. I installed these plugs when I installed my cam, valvetrain, oil pump and timming chain last summer. I have been watching HP Tuners on the car frequently lately and I noticed constant misfire codes at idle. Decided to take a look at the plugs today and check the gaps. Id say this gap is custom at best.. What do you think is going on here?

No others look like that. I am the one who installed the plugs, I suppose its possible that I did it on the way in, but it definitly wasnt done on the way out. Im not a big fan of the foreign object in the combustion chamber theory, but its possible. This is cylinder #4

for a standard tapered seat plug. Is this a non-
standard application, perhaps projecting too far
into the chamber? Any spare heads you could screw
one into and see whether it might break plane?
(Or since it's piston-out-of-hole on these motors,
even close to plane?)

Its supposed to be a TR55

Hi Folks
I would find it hard to believe that happen inside the engine unless something was inside the cylinder which would have damaged values, etc. Somebody might have dropped the plug during installation or something and not noticed the damage. Just my two cents

I am quite certain I didnt do that before I put the plug in the car. I didnt have the exhaust manifolds on, and I was doing it from underneath the car on a hoist, so there was no struggling or weird angles. I wont say I guarantee it, but Im highly doubting I did it during install.
put a plug in it and star it up if its still missing then compression/leak down it. Im gonna gp for the object in the cylinder theory. try fishing in the hole with a magnet. I saw a guy fire up his motor and it was knocking like a bitch from one side. pulled the plug and found what you found got a bore oscope and looked inthere and found a nut hammered into he piston. dug it out with a pick and pulled it with a magnet. hes put 20k on it since then no issues
1) Detonation, thats what I call the chunky stuff residing in the soot.
2) You guess its a TR55ix, or it is? Nothing really in b/w. It either says its one or not (if all the markings are gone, compare to all other plugs).
3) My vote is against anything in the chamber, there would most likely be a very noticeable mark on the grounding strap from the impact, not neatly bent over.
4) possible causes:
a) dropped or banged the grounding strap on install (wouldnt be on removal as there are no clean marks and the would have to be dropped to deform the GS like that).
b) manufacturer defect, having a weak spot in that particular GS.
c) leaned out a little in that cylinder, causing the detonation as well as excess heat deformed the GS.
Thats just my $.02

on a second look I agree with that there is no sign of impact besides being bent and when **** gos wrong in there it usally hits more then once. LIke I said sitck a plug in and see what happens
