I was changing my spark plugs today on a new to me 2000 excursion v10 and got to the last plug and this gem backed out with the plug thanks to the repair person who didnt loctite it in. what do I do ????
Kris, sorry that happened. What part of UT are you in? I suspect a time-sert is in your future. What cylinder did the heli-coil come out of? I am in the process of purchasing a time-sert kit, and would be happy to help with your conversion to time-sert, I am in Midway, UT. Only issue is the hole may be enlarged, and require the larger time sert than typical.
its not helicoil its just a crappy knurled insert they didn't loctite in so it came out with
the threads are still there but i suspect the knurled end boogered the first couple. so I am thinking of lightly chasing the first few threads with a greased tap.....idk i can tell you what size im at but if i reverse thread the whole shebang i can feel the thread want to engage and get a full turn before it snugs I just don't want to risk it I would rather clean it with a tap......Mike I would consider that option what would it set me back to have you help me ? what is the cost of the insert ? I am out here in the Vernal area
Kris, no cost to help, just it would be my first time sert repair. Vernal is quite a cruise from Midway- do you have a air compressor at your location? What cylinder is the insert from?
Others will likely give good advice on saving your initial insert, I am not seasoned at that- I suspect that a thread chaser, cleaning the threads with brake fluid, using air to clean any debris from the cylinder, and putting the insert in with locktite red may be a course of action, but others on here will give much more experienced comments.
Does that make sense if I put that plug in and reverse spin it you can feel the click of first thread engagement. And start screwing it it goes about a thread before getting some Resistance
. My gut feeling is that I could put the wrench on it and it would self chase the threads. Bit I'm not that gutsy....needed this vehicle by the first of july dangit. It's the back one driver's side thank goodness not passenger....
Helicoil or a knurled insert IS NOT A FIX for this problem under any circumstance whether its thread locked or not. The correct fix is a timesert kit, though it's kinda pricey it's the only way to properly fix the issue unless you swap heads which is $$$
so if the thread is clean and ok can I just put the lipped timecert in ?
You'd have to run the Timesert tools through the correct process, but a standard 51459 insert (in the 5553 kit) should make for a successful repair. Since the Helicoil insert didn't "blow out", there's no concern that an oversized insert may be required.
projectSHO89 is right. Had a M14 spark plug blow out of my 5.4L recently, bought a TIMESERT PN 5553 kit for $450 and fixed 'er right up. Drop dead idiot proof system, repaired threads much better than factory set-up, repair should last a lifetime. Had it fixed in 45 minutes, start to finish.
I would measure your blown out "insert" w/ a micrometer then call TIMESERT tech support to get the dimensions on their standard #51459 insert & their recommendations.
The standard #51459 Time-Sert may do it if your hole is not too big - else the Big-Sert will definitely do it. Have also heard some good things about the Cal-Van system, may be worth checking out.
Some "mechanics" poorboy some really cheesy fixes. Stopped by a shop the other day, the enterprising mechanic proudly showed me some chineese taps which he had welded into some modified deep sockets... It worked for him, not too sure about the long-term reliability for his customer.
More than half of the inquiries about renting my 5553 kit have been from blown Helicoil Save-a-tread inserts like this one. Of those owners who followed through, every one of them repaired the blown-out hole with the stock insert (it's 51549, not 51499, btw).
As I already noted, since the OP's insert was not blown out, there is zero risk of needing an oversized insert.

"Triton insert p/n 51459 included in 5553 kit" - yes, that PN is easily transposed...
TimeSert is the best repair. It's not easy to hear since you were only looking to do a simple spark plug change, but it is the best solution for a long term fix.
