Best tool ever!!!!!!

I am very pleased with this product!! I bought it because I blew a plug out of my ‘01’ Mustang GT and what I have studied from other inserts, this is the best on the market! I was nervous at first drilling into my heads but with the provided guide, it’s idiot proof.
I originally bought this tool to do just one cylinder, but I went ahead and replaced them all and I’m glad I went that route because who knows when another one would blow out. Once you have your motor apart to access the spark plug holes, it only takes 10-15 per cylinder. I highly recommend this tool to anyone who runs into this problem. I am very pleased with the product and the quick shipping. Read full review...

Great product!!!

I bought this kit for my 2002 f250 5.4 triton. The kit was shipped and delivered with in 4 days of paying for it. Then the instructions were very easy to understand, as well is had a DVD to watch that showed you step by step of what to do. It worked flawlessly!!!!! I ntend to do all of the spark plugs within the next few weeks. If you ever have problems with the spark plug blow out, this system is the only way to go!! You will not be disappointed as long as you follow the instructions..Read full review...

Great product!

I had a temporary thread installed but there was air still escaping through the cylinder...but I bought the CALVAN kit and not only did it fix the issue, it also turned the engine light off!!! Excellent product made specifically for the TRITON motor!!! It's definitely worth the money!!!Read full review...

Works as designed

I have never use this Kit prior to this. Just follow the instructions it’s easy to use. It was going to cost $300 to have this done, this kit only cost $223 and only took me 20 minutes to do it. I’m a novice. My expedition has 221,000 miles. This is only second time I’ve blown out a plug. If it happens again I have the kit already and it won’t cost me anything. I have seven inserts left. The only additional cost for Loctite 271, epoxy,and long tube blowgun.

Thanks,

Danny Jones

Great Kit, worth every penny, saved thousands doing it myself, excellent quality

No Need to pull the heads, this tool was easy and fool proof to use.
I did 8 cylinders with it as i did not want to have to do it again, It took a little time and work to do it wright but its done.
Its very important to get an endoscope to inspect and to flush out each cylinder to insure there's no chips left when your done.
Tips-- Follow directions carefully, Use good quality Cutting oil and plenty of it, after blowing out flush cylinder twice with brake cleaner and then with WD40 to lube cylinder when done.
This kit saved me a couple of thousand dollars to have it done at a shopRead full review...

Calvan 38900 is the only way to go for you 4.6/5.4 2 valve ford engine

This kit actually works very well.easy to use..i want to put out a little bit of help for some people.if you are unsure to buy this because you think the hole for you spark plug is to big. you can order just an insert from wise tools or even one of the Chinese knockoff inserts the fake ones have a different thread but it is however the exact same size in diameter.so you can do that and if by chance it is to small for your engine.you have 1 more option you can get a time sert big sert 5600 kit which is about double the size after that you have to get new heads or take your head to a machine shop.i hope this helps Read full review...

Great tool

Took me 45 minutes to fix my dad's truck compared to how long it would take to replace the head. This tool is precise, and nearly fool proof. Worth the money.
We used this on a 2005 f150 with a 4.6
We used an air ratchet for the drilling and tapping, followed by compressed air down the spark plug hole to blow out and metal shavings.
This is a great kit and the inserts are way better than the cheap ones from any auto parts place.
Cheap won't be good, good won't be cheap.Read full review...

You just gotta love this tool and the results you’re going to have!

Truly a life and dollar saver. Gives you all the instructions needed it’s up to you to ensure successful completion. Took me a couple of hours to fix 1 bad plug thread because the head was installed and not as accessible as if it was off on the work bench. But I enjoyed the results. Car runs perfect. Thanks to the inventors and vendors.Read full review...
