[DML] Re: Spark plug replacement

["content22207" <brobertson@xxxxxxxxxxxx>]

Care to reopen the ever popular high voltage ignition controversy
while you're doing your tuneup?

Use a very long socket wrench extension (10"-12") and rest it against
the intake rails. You should then be directly above each spark plug well.

Remember that you're dealing with steel spark plugs in aluminum heads
-- they'll probably put up a fight. Be firm but not too aggressive --
you don't want to take any aluminum threads out with the plugs. Some
people claim warming the engine up first helps, others claim that
actually increases the risk of stripping threads out.

Helicoils are available for damaged holes, but here's a good question:
aluminum is non-magnetic, so how do you get tap shavings out of the
cylinder? At least the helicoil itself is steel (usually stainless).

You don't need to tighten the crap out of the new plugs -- they will
seize just fine on their own.
