*When threading a blind hole, the best way to clean out the chips is to use a ball inflater needle in a blow gun. You can make an adapter using a 1/8-NPT fitting (which is a close thread to a blow gun nozzle) to adapt the inflater to it. | *When threading a blind hole, the best way to clean out the chips is to use a ball inflater needle in a blow gun.

*To keep chips from falling into an engine when rethreading a spark plug hole, put axle/bearing grease on the tap. This will collect most if not all the metal chips from falling into the engine. | *To keep chips from falling into an engine when rethreading a spark plug hole, put axle/bearing grease on the tap.

*Bolts of different sizes are torqued differently. Smaller diameter bolts are generally torqued in one step. Larger bolts are generally torqued in at least three stages. 1/3 of the torque spec, 2/3 of the torque, then full torque. For example, if cylinder head bolts are supposed to be torqued to 90 foot-lbs, then they would be torqued first to 30, then to 60, and finally to 90 ft/lb. | *Bolts of different sizes are torqued differently.
