So I was bored today and decided to go ahead and change the spark plugs in our 2006 Honda Pilot at 96K miles. First one comes out and new one goes back in just fine. Then I move to the middle plug in the front bank and as soon as it broke loose, I could tell something was wrong. It feels as if it is crossthreaded or something. Makes a very slight grinding noise if I try to loosen it anymore and I can't loosen by hand. If I try to tighten it back up, same thing. I haven't turned it much since I could tell as soon as it broke loose something was off. What do I now? Keep loosening it with the wrench or am I just doomed for a more expensive repair by my mechanic?

Well, I own a 2008. All 6 of mine came out OK.
I have heard around here that our generations' Pilot's may have the ability to spit plugs due to them not being tightened down properly at the factory. I took mine out at 90k and all were tight.
Perhaps you had a loose one, and it cracked due to vibration, and you finished the "cracking."
I would research (sorry you are in Houston) mobile spark plug removal (think the Ford trucks with the plug issues) around you and I bet they can help.

Spray for WD40 and work it back and forth to see that helps.
I usually spray some penetrating oil before I start removing them.

Pour a few drops of oil down the spark plug hole and let it sit, or some Liquid Wrench or something.

Unfortunately this is common on the Honda 6, plug on cylinder 5 gets seized. Probably going to have to get the plug out then helicoil that cylinder.

I'd try the oil. I think there's a good chance there's carbon deposits holding it in. I just the ones in my Liberty and some made some interesting noises coming out, but I just would loosen a bit, tighten a bit till they came out ok.

Thanks. I'm going to soak it overnight and see what happens in the morning.

I always use some PB Blaster on a hot engine before removing spark plugs after engine has cooled down. The grinding could just be a bit of carbon built up on the end of the plug. Oil it a little then remove it.

It looks like most of you were right about it just needing some penetrating oil. Rather than waiting overnight I went ahead and tested it and it seems 3 hours of soaking in WD40 "specialist" penetrating oil was enough to solve the issue. The plug came out smoothly. You could tell a difference in the discoloration and slight amount of carbon on this plug versus the first so it seems that's all the issue was. I broke the remaining 4 loose and are letting them soak now. Thanks for the responses.

Make sure you use anti-seize compound on the new plugs.

Just a dab of anti-seize. It's easy to overdo

+1 and as posted just a little on the threads and tighten the plugs just tight don't wrench them in. Waiting for the never use anti seize gang to chime in. LOL

And its probably a plated plug that got stuck which would be nothing new. thumbsup

I've never used anti-seize, but I cant think of a downside to it, unless you use a torque wrench on your plugs, which I donr.

I'd probably use the aluminium stuff in preference to the copper.
