removing stuck spark plugs?
I was trying to do a little work on Bec's Sequoia this morning but got stymied but stuck spark plugs. I didn't want to crank on them too hard for fear of breaking them off. Can I spray some Liquid Wrench down and let it penetrate? What else can I do to break them loose?
On new plugs, I've always added some anti seize but I was just reading some stuff about not putting it on the denso/ngk iridiums. Is that really an issue?
