INSTRUCTIONS
This is not recommended as an "Over the fender repair" Due to the long pilots on the reamer and tap, there is a possibility of the pilot breaking off and falling into the engine.
Before you proceed:
Make sure that the head is raised above the working surface at least an inch or 25mm so that the pilots on the reamer and tap tools have clearance as to not hit the surface below. If repairing on a work bench this can be accomplished by using 2 short pieces of 2"x4" wood to raise the head from the surface then secure the head in place.
Instructions are using a block of aluminum for better viewing. This repair ca be done on the vehicle at your own risk.

- Using the wrench provided, place the reamer into the square of the wrench and tighten the set screw to secure the reamer in place. The pilot on the reamer will keep the newly reamed hole square to the original threads Picture A.
Ream the hole until the black stop collar bottoms out on the hole and spins freely. This will create a countersink for the flange of the insert.

4. Screw an insert onto the driver and into the newly prepared hole. Picture G:
While screwing the driver into the insert you well feel the driver start to tighten up, with a little more power continue through the insert until it loosens up. The driver will cold form the last few threads of the insert locking it in place. Picture H.
Remove driver, repair is complete. The new steel threads are now square to the original spark plug hole.
Note:Technically the spark plug size on the 3 valve head
is a
M15.5x1.5
which
we consider a special M16x1.5.
