    I had a plug seized years ago in a different engine but the results were similar... the head going to the machinist.

    I've heard different arguments over the years about whether or not to use anti-seize when installing new plugs. I'd make sure the shop follows the Jeep service manual's recommendation to try and keep from having a repeat experience.
    In over thirty years wrenching professionally, I've never seen steel sleeves for spark plug threads unless someone messed up and installed a heli coil. Are These heads different?

    Fair? Not fair? Cracked sleeve...

    I've found anti-seize to be a friend on motors with aluminum heads. Hell, I've shot a spark plug out of a cylinder head, taking the threads with it. That required an aluminum plug to be welded in and then a new spark plug hole to be cut and threaded. Weee...

    If you would pry your sorry arse out the Scottsdale Fashion Square once in a while you would know more about the BLM and the USFS (you do know those acronyms, right?).

    I coulda sworn that someone told me they did. Just Googled and couldn't confirm. I should've done that first. Thanks for the correction.

    If it didn't then you get into a lot of grey area. Let's face facts, both parties knew pretty early on there was an issue with the #2 spark plug. Chances are any shop would have ran into this issue and you'd be facing the same repairs either way. From here it goes back to communication. If you authorized repairs, pay the man. If you hadn't authorized the work, it doesn't change the fact that the repair needed to be performed. The only thing the shop took away from you at that point was your choice in who performed that work. If you're comfortable with that shop performing the work then I'd pay the bill and go on with life. If you would have preferred someone else perform the work then bring that up and see if they can give you a discount.

    edit.

    For the record, $900 for the additional work sounds like a very good price as well.
    I'm going with this. Many times mechanics will encounter problems while trying to make a simple repair. It sounds to me like they put your vehicle ahead of others in an attempt to get it back to you as soon as possible.

    **** happens.

    was going to be my first question. But it was the head that was removed and machined. Sooo, what is this sleeve they're talking about?

    Same here. "Sleeve" to me means cylinder liner.

    Either way, it sounds like the shop is trying to do right by you. I've been in a similar situation with another car. Had a Mazdaspeed3 with a bad front wheel bearing, and decided to have a friend's shop do the work since it requires a press to do. Unfortunately at some point the stub axle and bearing had seized together so hard that no press he could get his hands on could split the two, so the job turned into a new steering knuckle and CV as well. Nothing to be done there except pay for the extra parts, because the job wasn't doable without them.

    If they attempted to drill the plug and use an extractor, and drilled all the way through it, then installed the new plug and started it with foreign material in the cylinder, you could have a damaged cylinder sleeve/liner. But it clearly says the head went out for machining.

    My JK threw an error code for a misfiring #2 cylinder. I didn't have the time or patience to work on it, so I took it last minute to a shop while on my way home from work the night before leaving town on a camping trip.

    The mechanic squeezed me in 10 minutes before closing to replace plugs and wires.

    When they got to the #2 plug they stopped because they couldn't remove it. They asked I leave the Jeep overnight, so it would cool down and they would remove it in the AM.

    Morning came and hours later with multiple promises, but failed communication attempts, they finally told me they cracked the sleeve pulling the plug.

    Now they removed the head (drivers side only) and are in the process of getting it machined, putting in a new sleeve and putting it all back together.

    I have a bill for $900 for the machining labor, sleeve install, and labor to put it all back together. This is in addition to the $200 charged for all new plugs, wires and labor.

    Fair? Not fair?

    Thanks in advance!

    Not fair. They did the damage and it should be up to the shop or mechanic to take care of that damage at no cost to you.
