Really, I've never seen that happen before, break the porcelain yes, strip the thread yes, but break through the body of the plug no. Wow you must have arms like a lowland gorilla. That must have been really stuck.

It broke off at the red line.... I'll post a pic of it when I get it back tomorrow.

These aren't 2 piece like the old 3V 5.4L, correct? Those were expected to break, but these... Makes you wonder if there was a defect or foreign material in the metal.

I installed the putco lower grill on my ranger. I had ideas for the hidden winch, but I haven't been doing any sketchy offroading as of late, so I closed the gap.

My arms may be as long as a gorillas, but not as strong :p
Sooo, 3 techs tried to get it (#4 cylinder....way in the back) out without breaking/stripping it, but no luck. The service advisor gave me 2 options: 1--Give 'er hell and hope it comes out. 2--Remove the head, extract the plug, then fix and replace it. If give 'er hell didn't work, they'ed need to remove the head anyway.
So, they gave 'er hell and it stripped. Now, they're ordering new gaskets, head bolts, parts, etc, but some are 1-2 weeks out. Most expensive spark plug change ever !!! ~$2400.00
Shit Happens.......

Oh no sorry to hear that, I suppose they won't consider a heli coil, if you put grease on the drill and tap it doesn't drop chips into the cylinder. A lot easier than tearing the head off.

That is almost unbelieveable. Are they replacing the head? Guess never seize is needed. Could that be caused because the plug is steel and the head is aluminum, galvanic corrosion?

Thats what I was thinking, it being the rear plug. Maybe a victim of water leaking into plug well and solidly rusting plug to head via corrosion.

Since it's the #4 cylinder, access is pretty limited, getting a drill, tap and heli-coil in there would be very difficult with cluttered clearance from above. No rust on the plug or in the hole, mine has an engine cover, so it wasn't rust. The galvanic response between the steel and aluminum is the culprit, so anti-seize would definitely help in any future spark plug changes. I asked the advisor if they were going to install a heli-coil, and he said "a what?".....and he had never heard of ARP bolts, but he's just an advisor, so.

It sounds like they will extract the plug, put in a heli-coil and reinstall the head. This really makes me want to pull any spark plugs in aluminum heads, apply some anti-seize and re-install, just to put some of the advantage on my side if they ever needed to be changed.
