TIME-SERTM14x1.25 Spark Plug Thread Repair kit p/n 4412E-111

This is my second time using TimeSert (did my caliper bolts a few years back and have had zero issues) and it's been no different than my initial experience. While the price may seem high, it's worth every single penny.I used this on my 05 Acura TL and it was the perfect tool for the job. If you're not taking the head off, I would HIGHLY suggest getting some grease. WD-40 will work, but it fails to catch all the metal from cutting. Before you start cutting, make sure your engine is on the compression stroke for the cylinder you're rethreading. You want the valves to be closed for when you blow any potential shavings out.Liberally fill the gaps on the step tap with grease and put a decent blob on the tip as well. Cut 4-5 quarter turns and back it out. Clean the tool, re-grease, and do 4-5 more quarter turns. Repeat these steps until there's no more cutting resistance. Doing it this way will ensure barely any metal gets into the cylinder. If you need a video demonstration, look up realfixesrealfast on YouTube, he's got a great three part series. Given the clearance in some engine bays, you may have better luck using a ratchet with a 13mm socket to turn the bits. After cutting is complete, use a rag to remove any excess grease from the hole. Use compressed air with a very small hose to get down into the cylinder and blow out any loose shavings. Use a hose that is about half the size of the hole so any potential debris will have room to get out. Be very thorough with this step. If you used enough grease and didn't get too greedy with the turns, there should be very little metal in the cylinder.Go slow, be patient, and this will fix your problem 100%. Best of luck!

Works awesome. Way better than replacing the cylinder head

Successfully repaired a '11 Honda Fit with the head in place. Saved heaps of time, money, and aggravation.The job went very smoothly. Filled the tap flutes with grease and then cleaned the hole with acetone soaked rag squares held with flexible grabber tool. The starter threads on the tap make it almost foolproof.If you are new to stuff like this, take your time and triple check everything as you go - the tap angle, the valves are up out of the way, the threads and seat are fully cut, etc. With time-serts the biggest worry is that the insert won't screw in all the way, but will catch and expand before bottoming out. If this happens at the bottom of a spark plug tube you're going to have a heck of a time removing it and trying again.This is a highly quality set, but for the price it should come with the high temp thread locker.

Blew a plug out of my Toyota Sequoia 4.7V8. Total repair time about an hour. The TineSert set is expensive compared to the cheap knurled top inserts but they work and don't come out. I've had the knurled- top inserts come out.It's still cheaper than pulling the head!Only issue is that on the deep plug wells of this motor, the seat cutter is almost impossible to remove from the stem of the tap. You can't reach far enough down to get it even with a magnet tool. The supplied driver tool can't unscrew the tap because the seat cutter is on it. I used a 3/8 drive 6"extension backwards. The female on the extension fit over the male square of the tap and I was able to unscrew the entire thing and remove it.Make sure your piston is all the way down before you start so you don't hit it. Use lots of grease on the tap to lubricate and to catch the metal chips, take the tap out a couple times during the threading process to clean the chips and put on new grease.I used red loctite on the insert even though it didn't say specifically to do so. Make sure you oil the insert installer. The insert only screws on the installer a couple turns, that's normal. Once the insert bottoms out on the head the tool will thread through the insert and expand it to lock into the head. After it starts turning easier stop and remove the tool so you don't drop it into the cylinder.

I ordered this st 2;:40pm on the 24th and it was delivered to my door at 9:30am in south Carolina from Pennsylvania!!!! Holy cow I thought I wouldn't see it until Saturday, well needless to say my Mini got fixed today 2 days ahead of schedule!!!! The Time Cert was complete, packaged properly and had 5 inserts as described, QUALITY TOOL!! worth the money saved 2k on a repair for a new cylinder head instead fixed for 300 bucks abs 20 min. WILL BUY AGAIN FROM THIS VENDOR!!! THANK YOU FOR SAVING MY CAR & 2K!!!

Rethreaded spark plug hole number 2 on a 2007 Honda Fit at 257000 miles. I was driving on the freeway and the car started sounding like a motorcycle and it was because cylinder number two popped out the spark plug with the coil. Purchased the timesert kit 4412e-111 from Amazon. Made sure that the Piston was down by putting a hanger into the spark plug hole and turning the motor by hand clockwise (never turn counterclockwise or you will damage the engine). Once the hanger went all the way down then I knew that the Piston was down. I was concerned about the valves being open or closed but the Honda mechanic said it really doesn't matter as there will not be a lot of damage but try to blow out as much of the aluminum chips thay you can. 1. Put WD-40 grease on the tap, inserted the tap into the hole and kept turning until I could feel no more resistance. 2. I placed the seat cutter and began to clean the seat for the sparkplug, I did about 10 turns. Then removed the seat cutter and the tap. I blew out and vacuumed the little aliminum chips as much as I could out of the cylinder head. I placed the driver into 30w oil then screwed the insert into it and then screwed it into the spark plug hole. I was met with resistance but the instructions say to keep turning until you no longer feel resistance but not too long because you don't want the driver to fall into the cylinder head. I turned it three or four times after I no longer felt resistance. Put some anti seize on the spark plug and put it in, torqued at about 15 lb then put the coil on. I have put a thousand miles on the car and it's running like brand new!
