TIME-SERT 5600 Triple Over-Size For Spark Plug Thread Repair Kit

This was really easy, it took some time but by following the youtube video that WiseAutotools.com posted, it went smoothly and perfect. I used a snake camera to check that each step looked good down in the port and it all went perfect. Saved me thousands.

Excellent quality tool kit. Purchased to fix spark plug threads on a 2008 4.6 F150 after a previous repair from the parts store failed. A lot of reaming but I am confident in the end result. It's definitely NOT coming out! I also bought the 5678 add-on kit to be able to install the smaller of the two inserts by itself. I know a lot of guys with F150's so I think these kits will be used more in the future.

This tool worked flawlessly! Well thought-out design. Instructions were easy to understand, no guesswork. Saved a low income single mom from having to deal with an expensive repair.

Pricey kit but works as advertised. My Lincoln was fixed once and it didn't hold. I watched the videos and took my time and it took about an hour. The next one I do will probably be done in 20 minutes.

We had a 2004 Toyota Sequoia come in with a helicoil insert in the spark plug hole that had burned through the side of the insert and the threads of the spark plug. We were worried that we might have to pull the head off to get it fixed. After doing a little studying and speaking to Wise Auto Tools we decided to give it a try. It worked great and now we have the confidence that we can fix most any spark plug insert problem especially the extra big holes. We do own a different brand to fix the smaller holes on the Triton engines which we also bought from Wise Tools. The product is great and the technical advise and service far exceed any type of internet based company. We will continue to look to Wise Tools and Denlors Tools for our specialty tool purchases. They are even very competetive in their pricing. Thanks again.

First looked at the Time Sert 5553 but realized my spark plug hole was going to be a little too big. Used painters tape on a 3/8" extension, slowly building it up until the size of the hole was reached. Measured it with a digital caliper at .67". The 5600 works on holes up to almost 3/4" so it was a no brainer. Great kit. Was done with the repair in about an hour! Would have given this kit a 5 star but you can't use it to install "just" the smaller of the two inserts without the 5678 add on kit. Also should come with the 389-4000 valve closed checker. Would like to be able to install the smaller one by itself if I ever have another spark plug blow out.

Used a parts store sav-a-thread kit and that blew out. Took it to a shop and they fixed it. Not sure what they used but that blew out. Researched on the interweb and found the 5600 last time kit. Easy to use and great quality repair. Wished I would've found timesert before settling for the parts store crap!

My shop had an 02 Ford E-150 Van with a blown out plug on cyl. #5. Put a repair kit made by Napa and it came out also. I did my homework about this issue and found this kit and ordered it. When we got it into the shop I had my Shop's Top Tech look it over then we installed the inserts from Time-Sert 5600 thread repair kit and my customer is a Happy Camper. And so is my shop Husk & Son Complete Car Care Evansville, IN 47714.

Bought this like others to fix a spark plug hole that was repaired before by some other kit. This kit #5600 worked great. You can really sense the quality of the tools when you're using it. Thanks!

A shop repaired one spark plug hole for me and charged $700. They said removal of the intake was necessary. It blew out after 2 months. I found The Time Sert 5600 online. It worked great. It was for the #5 cylinder. Great laminated instructions. This was on a 2008 E350 van. I also have 2004 E250 van and it blew #3 out a week after purchasing the 5600. Again, it worked great but sure is a bear working on vans I would highly recommend this kit to anyone, the quality of the kit is great. Thanks again, also customer service is A+
