Quit being lazy and pull the head to do it.. a lot safer.. unless you want a bunch of shavings sitting on top of your pistons and then scarring cylinder walls go for it

^ Sad but true. Less shavings, more room, the ability to CLEAN the shavings. Metal shavings in the CYLs are NEVER a good thing, but aluminum against steel? I think steel would win. But still not a good thing at all.

And if it wasn't threading right you went the completely wrong way by keep going. If it won't thread in by hand, there's something wrong. It's a 50/50 chance if the threads can be fixed. Worse comes to worse, you'll end up heli-coiling the head.

don't use too much force on a spark plug.

^ Right.. There's a TQ spec, but I've just always went by; hand tight till it seats all the way, then snugged down with the ratchet. A Tight-snug thing. You can do anti-seeze thing.
