Just looked at the spark plug after turning the vehicle on, theres a lip in the interior wall, so Im sure when I turned the engine on the insulator/electrode blew out instead of being sucked into the cylinder. Thanks for all the help guys. jeep will be towed to a shop 4 miles away and they should have it done by tonight or early morning. I'll tell them to use antisieze on the other 3 I havent installed.

edit:

this piece that I found laying on the floor confirms that there's nothing in the cylinder head

Yeah that was the first thing I was gonna mention. If the porcelain fell in the cyl, you're s o l. The head would have to come off. U got lucky on that one. Hopefully the extractor can get it out in one piece. Heli-coiling it would be a bummer. Hope it works out.

Just picked up the Jeep this morning from the shop, were back online

They heated the engine till it was hot, and put an extractor to it, the other two spark plugs they replaced were also hard to get out. all I can say is Im pretty lucky.

Why dont they put antisieze on there to begin with. Should be a "snap" to get out next time around. LOL

Glad it worked out for you, I learned a valuable lesson on using anti-sieze.!

I know from being a tech they say not to pull plugs outof a hot engine but i always let it run enough to get it warmed up a bit , not full temp but about 5 min of running it helps to get plugs out with out that problem. Of course antiseize before going back in with new plugs.

So, couple lessons learned.
1. Have the right tools, extensions, pivoting wrench
2. Use 5/8 deep socket to loosen and tighten instead of spark plug socket
3. Have engine warm before pulling spark plugs
4. Anti seize
5. Anti seize
6. Anti seize
7. Let a shop do it, if they break it they fix it! (should be #1) lol
8. put back the hose to air filter, genius shop tech. forgot that.
9. Look back and laugh at it...enjoy Jeep

Glad it worked out!

How many miles are on the motor? And are those factory plugs?

Going against the grain - Personally I'm against anti-seize on plugs. I've used it in the past, and all it really did for me was coke up on the threads. BMW (wifes car) does not recommend it; says it can cause the plugs to have a poor ground to the head.

One more thing -- everything I have heard about aluminum heads is to never remove plugs hot! You stand a much greater chance of pulling threads out with the plug. I always attack plugs cold.

This is true but I have had no choice but to pull them hot (customer just drove in and is waiting for car) and have never seen or had threads pulled out. If I have the option I will warm up engine but not to full temp. Plus repairing damaged threads is way easier than trying to get porcelinout of the cylinder without removing the head.
