    The only thing I could add to this would be to stop right there if they are that hard and blow out the spark plug wells with air. Then spray in some penetrating oil and wait a few minutes. Then turn in a few threads and then out again. That should free them up.

    The other issue is the torque setting with 'wet' threads. If you are using lube on threads, the torque rating should be lowered about 15%. Putting any lube on threads increases the clamping force of the item being threaded.

    This is what I’ll do if it happens next change. Plus clean/chase the head threads. Maybe the old anti seize needs to be cleaned off each change because the old dries and bakes on?

    As I mentioned before...I don’t use antiseize. I also use NGKs. Might explain why I don't have issues.

    On a side note. This spring I did a plug change on my FIL's '04 Sienna. 17 years old and 127k miles....on original plugs. What a complete pain in the ass that was. Google plug change on a 3MZ V6. About as much fun as chewing your own testicles off.

    One saving grace? Those OE plugs came out as if they had been put in there yesterday.

    Say no to antiseize

    Yep, just did my wife's Sienna plugs for the third time a couple of months ago. You gotta pull the entire top end off that damned thing.

    My wife's '07 Pacifica was the same. Whole top comes off what a pita. But eventually she blew the motor so I win. Now I leased her a Kia Sportage that she likes and I gotta admit I like it too.

    I’ve done mine 4x and staring the 150k service in a few months. The first 3 times I used nickel anti-seize. The last one felt like the plug was tacky coming in and out so I felt it already had enough on it. I tightened them down each time with an inch-pound wrench to 168in-lb (14ft-lb). IMO pulling the plug out every 30k miles eliminates the fusing of plug to the head unlike some engines have with replacing them every 100k. I’m going to do the iridium plugs in my wife’s Honda at 50k because it’s easy to do and will prevent that.

    I change mine every 3 years regardless of mileage(average 24000 km.). When I did them at 3 years I used anti-sieze. I didn't like the feel of them coming out when I did them at 6 years - I worked them in and out and got them out fine. The first time I changed them they turned out with my fingers on the extension after loosening a 1/4 turn - as it should be. That is the last time I will use anti-sieze on plugs. I even ran an old plug in and out of each hole to clean as much off the threads as I could. The new plugs went in dry.

    Well that is what the book says...

    I did my wife's Sienna V6 and used several short extensions and universals and then a longer extension. I fed them back under the intake attaching them as I went in and managed to get the hidden plugs out and in with no issues other than some scrapes and bruises on my right arm. It took a while, a bit of cursing and a six pack, but a lot easier than removing the intake. You just have to make sure that the plug socket has a firm grip on the plug before you try it. I'm sure it would suck if it dropped the plug down in the hole. :eek:

    Morrow of the story: Sometimes the book isn't the best way.

    Yep, on 98 Sienna, I used a combination of extensions to remove/replace plugs without having to remove intake or air box. New Sienna's may be different. On 07 Lexus ES350, I had to remove the intake plenum and air box to access the rear plugs.

    I always use a light coat of anti seize on spark plugs if they're going on aluminum cyl head . In fact my $2400 AFR cylinder heads that are on my sbc in my Camaro require anti seize on spark plugs . It is clearly listed in the AFR assembly / instruction manual

    I always use a light coating of never-seez as well. I know the plug manufacturers say not too, as do some of the auto manufacturers, like Ford, but with the 100K mile plug changes on iridiums, most of them are very difficult to get out. This is one of those "religion" type topics where everyone has an opinion they swear by, but I've never had an issue with never-seez. This is what I use:
