    Any ratchet that clicks,unless it is a torque wrench, must be broken. To take the mystery out of all this, just use a breaker bar, get er done!
    If still a click, replace with new socket!

    Since the plug froze up again but it is about half a turn unscrewed, should I run the engine? This time I got a breaker bar to work with

    Run it. What's going to happen? The plug will loosen up and blow the coil out of the hole? Get it hot again, and try it with your breaker bar. Personally, I think your socket has to be broken, because I've never heard of three ratchets breaking, trying to remove one sparkplug.

    Best to get some better tools. All this "clicking" is rounding the corners of the plug's hex. If you think it's tough getting it out now just wait until the plug is stripped.

    If you can leave two black stripes from the exit of one corner to the braking zone of the next, you have enough horsepower. - Mark Donohue

    I'm 1,000,000% sure it was from the wrench. I got a breaker bar and I'm going to go back at it again today, but what are the chances that the threads or the top of the spark plug break?

    Rare, as I have broken the porcelain off and even stipped threads out the head, but never broke off inside the head.

    Alright, I warmed the engine up to operating temp and sprayed PB Blaster in like I did before. I worked it back and forth with the breaker bar and there was no clicking this time. After working it for a while it came out. I'm waiting for the engine to cool before I torque the new plug but I put the new plug in hand tight before taking it out again and the threads are still good :thumbup: . Thanks for all of the help guys, saved me a ton of $$$

    Okay, then throw away all three ratchets you used, and buy a good one. Ratchets do not click, unless they're broken. Oh, and put a small amount of anti seize on the plug threads.

    Buy yourself a minimum quality toolset, maybe Craftsman, S-K, that contains 3/8" & 1/2" drive ratchets.
    If you want top quality then look at Snap-On, Matco. Those ratchets you're throwing away , sound like cheap Chinese imitation tools.
    Probably bought at your local Walmart, am I right?

    I'd suggest chasing the threads given all the grief this plug gave you.
    Carbon deposits seem to be what does this, I wonder what benefit an "Italian tune-up" might have before pulling plugs out.

    I am having a very similar issue it seems. I went to change my plugs and coils this weekend after developing a misfire after installing the JB4. All plugs except on cyl #1 came out with ease. I had to use a 3/8" breaker bar to turn the plug in cyl #1. After turning about 90 degrees, I sprayed some PB Blaster in there and let it soak for about 20 min. It still wasn't any easier to turn. I tightened it back down and let the car run for a few min and tried again. It seemed marginally easier but after 1/2 turn, it wasn't getting any easier so I decided to tighten back down and not change it at that point in time. The car is a 2008 E92 335i A/T. currently has 93k on it and the service history shows the plugs were changed Jan' 2013 at about 46k. Would you guys recommend I take the same course of action that B00STED did? Thanks in advance.

    Exactly, 30-90 degree turns are fine(30-90out-30-90in-30-90out-spray-repeat)back and forth is the way to go.

    I think I will try this after letting the some kano kroil soak overnight. Thanks!
