Lisle Auto Tools manufacturing company was started in Clarinda, Iowa in 1903 by C.A. Lisle. The first tool his company manufactured surprisingly wasn’t an automotive tool at all, it was water well drilling equipment powered by a horse! Subsequent products were not automotive related either, remember old ringer washers? And how about the old style manual push mower? Some twenty years after the Lisle Corporation was first started, the tool company made its first automotive product.

New Specialty tool for handling Ford broken spark plugs!

© DenLorsTools.com If you’re a subscriber to our automotive tool blog, you know we pointed out in a previous post, the need for a less expensive alternative to the Ford Rotunda 303-1398. The SPX Rotunda 303-1203 removes broken spark plugs on some Ford 5.4 engines, 2004 and up. But it only works after the broken porcelain piece is out of the way. That’s where the new Lisle LIS 65600 automotive specialty tool, comes into the picture. The best way to try to prevent Ford spark plugs from breaking to begin with (per a Ford Technical Service Bulletin-TSB) is to loosen the spark plugs slightly and then soak them with penetrating oil. Sometimes the carbon build up around the electrode shield will still separate from the main part of the spark plug. So, in many cases the porcelain part of the spark plug will stay in. This prevents the use of the 303-1203. Rotunda offers the SPX 303-1398 to remove the porcelain or ceramic piece, but the pins included in this six hundred dollar kit can only be used once. The pins are secured into the center of the broken spark plug (where the electrode was) with loc-tite, then the puller is used to hopefully pull the ceramic piece out of the way, so the two hundred dollar 303-1203 can be used to remove the metal electrode shield.

Lisle’s Method, using the LIS65600 auto specialty tool implements a different approach. First, if the broken porcelain is stuck down in the spark plug hole, the first part of the Lisle kit is used to press it down a little further without breaking it.
