This is a Big Sert (Time-Sert's name for over-sized) kit which works when previous repairs with Heli-Coil type inserts fail.
This kit is not recommended for holes larger than .663" (16.8mm). See the Time Sert 5600 for holes up to .73".

The 51457 is the most popular fully threaded one which is 16.8mm long with a taper seat (requires 51484A to be used on setting tool). They are sold separately. Check to make sure the valves are closed without removing the valve cover with the 389-4000 Leak Tester.

Question: Will my fully threaded spark plugs (all the way up to the taper) work with the inserts that come in the kit which have threads only about 1/2 way?

Answer: Yes they will. If preferred, we also have fully threaded inserts (PN 51457) which have twice the number of threads for more holding power. *Note that partially threaded plugs will NOT install properly in the 51457 fully threaded insert so the inserts included in the kit have to be used. These inserts are still much stronger than the original aluminum threads.
