Any one used a Time Sert over the fender kit?

[Sniper X]

I need to do one on my trooper. It spit out a plug and doinked up the threads when it popped up and down before I stopped. Friggin shitty PO mechanic! All but two of the other plugs were finger tight!

i got all of them changed but the one that is easiest to get to thank God!

Looking for someone who has used a time sert who has some uh....time on the repair to let me know how it holds up and if they work as stated.

PLEASE don't tell me to remove the head, no friggin way. Id jerry rig it and sell it first. BTW its a 1999 3.5 with OHC so no friggin way will I remove a head to repair plug threads!

I hear theses got real popular with Ford techs on the V10 motors because they are notorious for spitting plugs from stripped threads.

bump for info...fingers crossed!

My dad a very simple and elegant solution to stripped spark plugs. He tapped them out to fit a plug with a a bigger thread. Time Serts are strong, expensive and not real easy to install.

They work ok-the main concern is adequate access, and of course cleanliness.

This is the tools we use on the Ford modular engines. It is kind of a pain it the ass and unless you can borrow the tool kit from someone it may not be worth it. The tool kit cost around $400.00 IIRC.

Sniper, how about asking this in the Garage section - might get more feedback there? Good luck with your fix!

PS, try Old's Cool too - just tell them you are working on a bike you found in your grampa's shed (maybe, say, a Henderson) and they'll be on it like a bum on a ham sammich!

had one in my z1 900 years ago when traveling. not many options to pull the head. it never gave me any issues and i over revved the piss out of it. so I left it alone.
just my experience.

I have attempted to use HeliCoil sparkplug thread repair inserts a couple times and failed both times . The threads cut fine and the insert is fine but I didn't get proper alignment in the head and the sparkplug gasket would not seal . Glad they were small engines that I could buy cylinders for cheap . Back in the old days I did tap out a couple heads with taper seat plugs to a larger size plug and keep on running with no problums . The tap would cut the plug gasket seat too so alignment wasn't an issue . SEYA

I used something very similar from Napa called a "Sav-a-thread kit"

It consisted of a threaded sleeve -- threaded on the ID for the stock plug and threaded on the OD for the supplied tap.

It worked by using the supplied reamer to enlarge the bad hole, then use the supplied tap to cut the new threads, then thread in the sleeve. Finally you used a supplied tool to tap the top of the threaded insert to supposedly spread it apart a bit and lock it into the hole. It worked fine as far as I can tell, and has held together for almost 5 years. However, I would not recommend using one as there is nothing to ultimately stop the insert from threading up or down in the hole other than the little knurls on the top that supposedly spread apart when tapped with the special tool. It's almost time to replace the plugs on that car and I'm dreading what is going to happen when I pull that particular plug.

I would definitely recommend a time-sert -- they have a shoulder on the top and the tap/reamer tool cuts a counterbore for the shoulder to screw into positively locating the insert preventing it from threading down into the hole during future plug installs. Plus the counterbore/shoulder gives a better sealing surface where the sav-a-thread kit had to be installed with RTV.

DON'T use a helicoil.

DO disconnect your ignition system and crank the starter motor after drilling/tapping to blow the chips out of the hole. Also duct tape some vinyl tubing to a vacuum and stick in in the cylinder.
