Includes Free shipping.  Also included from Wise Auto Tools with this kit is a Valve "Closed" Tester! along with helpful tips compiled throughout the years from our Master Tech that answers common repair questions for this application. Just write tips in the comment section when checking out. TIME-SERT 5600 This is the largest outside diameter spark plug thread repair kit available and installs a Big Sert insert inside of a triple oversize insert making this kit the largest Ford spark plug thread repair kit in the world. The outside diameter (O.D.) is .76". Since this kit uses the triple oversize insert which is the biggest repair insert available, it's capable on fixing even the largest spark plug holes. Holes that were damaged more than usual from a previous repair attempt that failed. If you already have the TIME-SERT 5553 an additional add on kit can be purchased to achieve the what this kit does as a "stand alone" kit. However, the 5600 kit cannot install just the smaller of the two inserts. If you already have a 5553 purchase the add on kit #5588. *Note the 5600 kit does not install the Big Sert alone. Tooling is provided for using both inserts together. If you would like the capability of installing ONLY the Big Sert (smaller of the two) inserts when the triple oversize is not needed, use the Time Sert 5678. The 5678 is the add on kit for the 5600.

Installed over the fender. The repair is done by installing an insert inside an insert to end up with the triple over-size outside diameter. The original (fully threaded) spark plug can then be installed saving the cost of replacing the cylinder head, gaskets and the labor time associated with R&R of the head. *Note that for first time repairs the 5553 kit is recommended.

*Please note that the progress of the depth that the reamer has reached should be closely monitored. In the video at around 7:08, we mention that the tool will not go but so far because of the collar; While this is true in most cases, we advise to be careful and stop once the counter-bore (the widest portion) of the reamer has been reached. Forcing tool to continue cutting may possibly cause irreversible damage to head. Questions please call us at 800-734-8665 x251. Get more free tips emailed when purchasing from us.

    This Saved two engines for me so far. I bought it because I needed it for my own van and then for a friends Mustang. It allows you to make the repair on the car immediately with little effort. The price is very worth the money. You can always sell it after making your repair. I keep this inside the house and may use it once or twice again in my life but boy when you need it you will be so happy.

    Saved vehicle!

    Posted by Gary W on 24th Oct 2019

    2001 Ford F-350 V-10 had two spark plugs blow out from same cylinder. Both times cylinder was repaired with over the counter repair kits. Spark plug blew a third time and while researching this issue I came across the Time Sert 5600 Triple O-Size Spark Plug Kit W/Leak Tester! I wish I had of located this tool previously! It fixed the problem and simple to use. Highly recommend it!!

    F-250 Super Duty 6.8 V10 1999

    Posted by Bill F. on 13th Mar 2017

    I bought a used F-250 Super Duty 6.8 V10 1999, to my horror, found out the hard way, an over the counter repair had failed on a blown spark plug hole. The time-sert triple oversized was my only option if I wanted to do the repair myself. Watched the videos, followed the directions, truck started right up no issues when the repair was complete. (3/8 in drive pneumatic ratchet is a must!) My only complaint, not with the kit, with the directions. Having been an aircraft mechanic for over 25 years, I believe more torque specs should be included. "about 20 ft lbs to install" does work for explaining when the die has completed. It would have also been helpful to know if the spark plug could be torqued to factory specs of 27ft lbs, or if because of the insert, the torque required is less. Maybe that will be answered in follow on instructions. Over all, extremely pleased! The repair went just as described. The kit arrived in a very timely manner and is in an awesome storage case with all the parts being laser etched with their part number. Management: Thanks for the review. Yes, normal spark plug torque spec is fine. The threads are stronger than original. Appreciate the commets and will pass them on to the manufacturer.

    Fixed without issue

    Posted by Kevin G on 23rd Jul 2016

    2002 Mustang fixed the blown out plug without any issues. My sons car, tried the auto store insert first (failure). We took our time carefully reading instructions on each step. Had everything done in about 90 minutes. Borrowed a bore scope to verify that all the shavings were out of the cylinder. Beats the crap out of pulling cylinder head.
