Re: Cross Threaded Spark Plugs

["content22207" <brobertson@xxxx>]

Are helicoil type inserts with spark plug thread patterns. Most parts
houses should have them. You'll find tapping aluminum very easy. Be
sure to vacuum all metal shavings out of cylinder before turning
engine. I'd recommend gluing helicoil in for 24 hours before threading
a new plug (old fashioned gasket adhesive -- the stuff in a can with
brush in lid -- dries like super glue. Made mistake of using to hold
upside down GM starter bolts once. Had to drill them out).

To avoid cross threading in future, never turn spark plug with socket
wrench until it is well threaded by hand (use extension like a nut
driver). Never force the plug. If it doesn't find threads in head,
lift up and gently try again.

PRV intake rails can make threading difficult. Use other hand to guide
extension closer to well.

I've found plug #6 easiest to install by not locking socket onto
extension. Just rest in square drive recess and it'll move like a
wobble extension.
