While changing my sparkplugs yesterday I discovered a multi-use tool of great simplicity.
As ya'll are aware, cylinders 1 & 3 sparkplugs are slanted toward the rear of the car and sometimes make insertion of a plug difficult to get a start on when threading in.
This is usually due to carb linkage interference and/or the interference from the maze of tubes, wires, fittings, hoses, cables, and cable housing retainers (if injected).
Simply pluck the cap off of a Sharpie and push it on to your sparkplug / voilĂ ! Just long and snug enough to not lose the plug assuring no stripped threads and easy removal of the "tool" after use.
Further: While replacing my newly turned vented rotors/hubs to the spindles (which requires removal of the caliper bolts) I used the other end of the sharpie to locate the top bolt holes and to make a tight alignment so as to allow easy location of the bottom bolt hole and threads (first) with the bolt and washer. No more thrashing around fighting the brake line resistance and weight of the caliper while searching for the receiving threads.
A spent sharpie is now in the tool pouch.......
