Review: Ford blown out spark plug repair made easy - This was used of 2005 Ford F150 with 4.6L engine. It worked perfectly for the blown out spark plug #3. Make sure piston is at bottom dead center. To determine this, I used a big plastic plug that kinda stuck in the spark plug tube and had a tiny bit of a seal. I crawled under truck and turned engine over for what felt like a lifetime, because it is hard to get to the crank bolt with the suspension and shroud...but it is possible. When the engine has both valves closed and the piston is at bottom ready to go up, that plug will pop out loudly. The use of the tap is easy. Fill the end of the grooves of the tap with grease to catch metal shavings. Go in 4.5 turns, take it out and clean tap. go in 4.5 new turns, take out and clean. Wash rinse repeat. Do not do excess turns or more metal will fall into cylinders. When done, use compressed air to blow out. I sprayed a little carb cleaner to get rid of grease. I used the longest thread insert. I gently and lightly coated the new spark plug with antiseize compound, and I used permatex 27200 red threadlocker on the outside of the insert. I very gently screwed this whole thing in the cylinder. I was patient and waited 45 minutes before starting. It has held up a month now. I recommend this over the $100's people say you need to spend on super duper tools. I just do not recommend people buy a old Ford truck with one of these motors! The inconvenience was horrendous, and the research was tough. I only saw a review here on desertcart that explained it like I am. So I am also sharing the process. Takes about hour and a half constantly getting up and down on truck. Maybe 12 times to clear hole, then to reassemble.
Review: Fixed a stripped out spark plug hole on my old chainsaw beautifully! - Honestly it worked great! Very easy to use! Just a ratchet and a bit of time! Heck I didn't even take the head of the engine off, just the exhaust muffler to get better access to the bore for cleanup. Just made sure I was able to get every last bit of metal shaving out (For the record I did coat the tap with grease to minimize shavings falling into the bore, but obviously it's not going to get it all). When I finished with the boring/tapping step, and cleaning up the area, all that was left was to put in one of the collars provided! There are 3 different sizes, and if you're fixing a chainsaw, you'll want to use the one smallest in length. Before putting in the collar, I coated the outside of it with a good coat of RTV (I used Permatex's ULTRA Grey). I then screwed the collar in until it was just BELOW flush with the surface, making sure that the "teeth" part of the collar were facing up/out! After seated, I gave it a good couple taps with the provided die using a hammer to expand those teeth on the collar and bite into the threads for a good, solid fit that wouldn't back out anytime soon! So far there hasn't been any troubles with it! It's holding very well! If you've got a stripped spark plug hole, this is a great solution! Definitely recommend!

## Questions & Answers

**Q: Does this works for a Ford Expedition 2001 4.6L triton?**
A: It worked really well on my 2004 ford f150. 4.6L.

**Q: What size socket to fit the tap?**
A: 3/8....the ONLY tap I found that has this absolutely necessary feature.

**Q: Which of the three inserts is used with a j19lm plug in a 12hp kohler ? thanks.**
A: The one that closet in length to your plug threads.

**Q: Would this fit on a 2004 gmc envoy slt 4x4 6 cyl?**
A: It has the potential to work, but the way the tool is designed it doesn’t work well. I had a spark plug blow out on my 1999 Ford F-150 and I tried this and it didn’t hold in the spark plug hole. Better look around before buying and find a better product. If you can’t then this maybe the only option for you without going to a machine shop.
