Re: Cross Threaded Spark Plugs

["David Teitelbaum" <jtrealty@xxxx>]

There are 2 choices. The first requires you to remove the head and
take it to a machine shop and have it welded and retapped. The other
choice is to go to an auto parts store and get a special thread insert
for just exactly this use. They come in a kit with a drill, the
insert, a tap, and a tool to install the insert. Take a spark plug
with you so they give you the right kit. You have to be careful when
threading steel things into aluminum, the aluminum is soft so if you
cross it it is the aluminum that gets ruined. If things don't go easy,
stop and try again. Forcing things with aluminum is not the way to go!
BTW you must be very accurate when drilling for the insert. If you do
it crooked the insert will be crooked and so will the the spark plug.
