Ford Explorer spark plug fix

Ford blown spark plug repair - Time Sert review

Vehicle: 02 Ford Explorer V8 4.6L

Many Ford engines from 1997 to 2008 with Triton heads may blow out a spark plug. Many companies have come out with a relatively inexpensive fix that allows the Head to remain on the engine, thus saving a lot of money in repairs. Although I have rebuilt engines in the past, I have never repaired this kind of damage to an engine. I wanted to record whether Time Sert's claims were as easy as they proclaimed. The answer for me was mostly Yes.

The only criticism was that I had no objective idea how much counterboring I needed to do. With the engine that I had, a Lot of counterboring needed to be done and I thought I had gone too far at one point simply due to the amount of time spent with this operation. I have done a second repair and decided to only use a hand ratchet on the counterbore. It took two hours to counterbore alone. I recommend an air ratchet for this reason.

Bottom line is that this works; It's relatively inexpensive; and I was overall happy with the product. As well, I can now replace more threads without buying anything more since it came with 5 inserts.

Thank you so much for this video, Dave. It allowed me to make this repair without incident. I have only a limited knowledge of mechanics. My 2001Ford Expedition blew the #3 spark plug. I have had 6 Ford vehicles in the past 12 years from the same dealer in Van Nuys, Ca. They offered me a "good customer rate" of $2800.00 to replace the head. My local shop wanted $1800.00. I am struggling to make ends meet as it is. You and Time Sert saved me. Thank you, again.

Hello rockkkkher,

They said to "place Lock-tite around the middle of the insert". Their instructions show a pic of less Lock-tite than I put (their pic showed on one thread). I think that this is enough given that they have a system that locks the insert into the threaded hole independant of the thread locker. The torque spec comes from Time sert and is the torque of driving the insert into the head. I did not see a spec for the spark plug itself. I have always driven plugs by feel anyway

Yikes! $375 for the kit?!? Given, it's better than paying a dealership $1000 or more to do it, or paying even more to replace the whole head, but still, that's a hefty chunk o' change for a tool kit, a bottle of red Loctite, and some steel sleeves. I wonder if any places rent out the kit and you can buy the insert sleeves seperately...? And was the spark plug blowout issue common on '92-'97 Crown Vics, or just the later '98+ models?

does this work on an 1998 ford explorer SOHC sport?

@fmac524 Thanks to your video, I was able to come up with an idea, I bought a boring kit for 216 pesos here in Mexico, I then welded a 1/2" x 12' ratchet extension to the boring tool. The process was not as clean and pristine as your video shows, I was able to get it done for just under $30 dls.... My 2001 expedition now has a good bill of health... Thanks!!

At first I thought he said he was gonna use the "time circut" like as if he was Doc Brown. Then I realized it was "Time Sert kit" haha
