    Spark plug difficult to install

    Hey guys. Usually when I install my spark plugs I can just use my fingers to screw them in, then torque them to 18 ft/lbs. For some reason though on cylinder 2 I can only get a few turns in by hand and it's becomes tight to turn. I can screw them in with a ratchet but I shouldn't have to. I tried cleaning the threads of the plug and adding anti seize but it's not helping.

    Anyone come across this before?

    I don't think I'm cross threading because it goes a few turns before getting tight.

    Can I chase the threads to clean them out? Would that get crap into the heads? Anyone know what size those are?

    Never heard of that either, sounds like a handy tool. Make sure you post how it works.

    to me that thing is scary.... I would be worried about cross threading it from the under side??

    Spark plug difficult to install

    Worked like a charm. You slowly increase the tension through several passes, it really saved me some $$$
