Reply To: Stripped Spark Plug Hole?

[Bob Wight]

Some folks might put grease on the tap to catch any metal shavings, but I would pull the head off.

Olcah – yes, I think 20ft-lb on the plug torque is too much. I got to 16 at the most or 1/2 turn of the plug after the plug gasket seats against the head when turning by hand.
