Stripped Thread Repair - Time-Serts BETTER than Heli Coils! - LS Exhaust Thread Repair!

[@RonCovell]

Alan - Wow, thanks for a great introduction for a product I was not familiar with! I can see that this is a big step up from the Heli-Coils I have used for years!

[@HotRodHippie]

Always happy to help, glad I could expand even your horizons Ron. Since I was introduced to these I haven’t looked back. 👍🏻👍🏻

[@thomassmith2239]

Another great video! 30 years ago I worked for a racing team that cnc machined various engine components out of magnesium and other exotic materials. Rather than tap holes directly into the magnesium we installed Time-serts to prevent later issues with gauling or thread damage.

[@HotRodHippie]

That makes perfect sense. I could see doing that in stainless components too. Put a steel insert in to prevent galling. Hadn’t thought of that. 👍🏻👍🏻

[@laurencevillegarage]

Soooo, I have an LS 706 head that I thought was ok (on first glance). I did notice a broken exhaust bolt which did not bother me. I have removed these before without issue. I didn't notice a cross threaded spark plug AND I really didn't notice that the 4 center exhaust manifold bolt holes were completely stripped out. I had fixed a spark plug hole before and that worked out just fine. What to do about the other 4? Luckily, I found your video! I bit the bullet and purchased the kit you used. At first, I was weary because the kit is not cheap. Worked perfectly! Worth every penny! It's a small thing, but when you can repair something yourself without having to go to the trouble and expense of paying someone else, it is very gratifying. Thank you for your video. I have gained new confidence in an area I previously found to be very intimidating.

[@tinygaragefab]

Cool little tool. Im my last video (22R-E part 2) I 3d printed a drill guide for a Helicoil repair on the block so that I could fix a stripped head bolt hole. I am pleased to say that my Helicoil held the head bolt just fine, but I would definitely have used these instead had I known more about them. (BTW, the 22R-E video is worth a watch if you have a few minutes.)

[@neosde]

Good explained, i did insert on caliper hole on hub of my ford steel rust free m9 1.25, would not trust helicoil on my breaks. Solid. Solution saves changing the whole hub leg of my car

[@felixf5211]

HFT sells a couple of sets of brushes, nylon and metal, the are perfect for clearing out drilled holes. Especially through holes. You probably already have something similar. Thought I'd mention it for those who don't know. BTW, I dig the bike.

[@SteveRivett]

That is the way to go. I think you can grind them down if they are too long. There are some other versions that have stakes to keep them from spinning.

[@Ghost915A1]

You just saved me from making a dumb mistake on my CL350. Thank you!

[@HotRodHippie]

I've said multiple times that the next CB I build, I"m stripping the engine and redoing every important thread with these things. Those bikes are great but the engine aluminum is sooooo soft.

[@LynxStarAuto]

That blue loctite is pretty useless on exhaust components. You need to use the 271 variant which is good up to 500° and can only be removed with heat.

[@kentrymason5566]

thank you this will fix my wife's car ,it's a cvt transmission. the bolt pan !!!!

[@darkfire112886]

Funny enough I follow you on tiktok but havnt not found you on here, i was researching this for my gen service class (Auto Tech) and you popped up lol Great video

[@Joe.Doucette]

I was first thinking.. bah.. it's another type of Heli-Coil. Wow. They certainly are not that. Very neat how the bolt expands the Time-Sert into the threaded hole to set it. Pricey to start, for sure. But go buy a quality tap and counter-sink bit and the initial cost isn't as painful. Thanks, Alan. BTW.. Nice bike.

[@HotRodHippie]

Thanks Joe. It is really something you have to get all the info on to see the value. Which is why I wanted to make this video. Once I really learned of them and experienced them I haven't looked back.

[@heyallenify]

On Mercedes M117 engines, stripped head bolts are repaired with TimeSerts, which is where I learned about them. Personally, I used them to fix engine mounts on my VW Jetta TDI with the ALH engine suspended off of a pair of aluminum mounts. The engine side of the mount is is threaded directly into an aluminum casting, and likes to strip after a few timing belt replacements, due to the torque spec of the bolt putting huge loads on the aluminum threads.

[@LynxStarAuto]

Yeah I work on German cars myself. Use them all the time on M6 and M7 hardware you find on a plethora of German products. Most recently, I did some on a CAEB 2.0 TSI. The vacuum pump mounting bolts. Someone hulked them on and stripped the crap out of one. Developed a leak from the mounting gasket.

[@michaelhallas6450]

At the end of the day you have a very strong and nice repair

[@rotarythread]

Additional tip, instead of marker use masking tape or painters tape would be more visible for you while drilling. Our product does the same, well not the same issue that you have lol!

[@cruiseoveride]

Do you need to countersink to the full depth of the countersink tool?

[@seanalexander9531]

Wow, great product! One to put on the wishlist I reckon :)

[@michaelhmfic8346]

Learned of these with the wonderful ford engines.

[@tomsuica8731]

Loctite 266 is the correct juice to put. Hi temp Hi strength. Especially in A high Temp app like this.

[@alantownsend5468]

IIRC Tim-Serts were GM's repair method for the Cadillac Northstar V8 cylinder head bolt holes

[@HotRodHippie]

You are correct. They seem to have been used by a few manufacturers for certified repair jobs. I know while researching for this I saw their website call out Cadillac for certain.

[@LifeWideOpen780]

Sick cb750. My first bike was a 1980 cb750 awesome bikes

[@HotRodHippie]

Thanks. I miss that thing, gonna have to remedy that soon.

[@SparkyBrownCow]

I ended up here looking for a thread repair option for my 3D printer; imagine my surprise finding myself in a MandicReally crossover episode.

[@wyattoneable]

That's a pretty slick "get out of jail" tool right there.

[@HotRodHippie]

When in a stick spot, this’ll get you unstuck. Maybe. 😅

[@junechris]

I have heard that this is a better thread repair. Is it better for spark plug threads too?

[@guillermonieri4203]

Thank you.

[@lg3053]

Good video. I hope I never have to do all this.

[@bobthrasher8226]

Strength testing video on YT which shows helicoil outperform time-sert. Check it out to see if test was fair. Maybe if your time-sert is longer than your helicoil it might perform better.... But if they're the same length, not so sure.

[@manguydude287]

Now I'm not going to say I won't 100% do this for a head bolt that pulled out 😅 but I will also be doing it with a power drill. I know there were machinists shuddering at the idea of that 😅

[@city7053]

Would i be able to do this repair and be able to torque to spec or im better of dropping a few points of from its recommend Nm torque for example if torque spec is 10Nm i should torque the repaired thread to 8Nm

[@michaelmounts1269]

Another great video...

[@Krunch2020]

The Torque test channel on KZbin tested them by ripping them out of cast iron. You might be surprised by the results.

[@koston777]

will Time Sert retain original torque spec?

[@ShersGarage]

They're as strong or even stronger done right. People use them to do headbolts and studs.

[@sav4208]

I have the same 317 heads and I stripped 1 or 2 of my header holes, so if m8 x 1.25 size fit yours will it fit mine as well?

[@sengchalaksangma8443]

Hi friend, can you explain me that my Alto car exhaust manifold's gasket leaking oil after repair change new gasket,what is the reason is that please do inform, thank you

[@rcrc5260]

Any help please, my ram 1500 looks like someone drill deep into one of the engine block holes and it leaking antifreeze slightly, how do I fix this problem?

if i want to repair m6 tread.. does the drill need to be 6mm or larger..?

[@1peanut]

I have M8x1.25 manifold stud that is striped. What size time cert do i need to use to fix it ?

[@dickeymoore3662]

I have a aluminum 6.0 LS engine and one of the holes in the block where the head bolt screws in yhe block is stripped out, will the Time Sert work for me?Thanks

[@HotRodHippie]

Yep. I don’t know the thread size of that off hand but Time-Serts have been used as official GM repair kits for Head Bolts (I believe mostly on cadillacs). Just have to find the right size for your need. I’d imagine if you contact the company they may be able to help you figure it out.

[@dickeymoore3662]

@@HotRodHippie ok Thanks

[@garagemonkeysan]

Nice video. Cool tool. Mahalo for sharing!🐒🙂

[@maxheadflow]

I'd bet that insert eventually pulls out.. If 8x1.25 was the original size but it was tapped to 3/8-16 the hole is already too big.. You'll need a fat timsert or keensert.

[@shawnbrascoupe401]

can this be used on a starter holes

[@HotRodHippie]

Sure. If you can get close enough to the block to install them. GM has included these in service kits for Cylinder Head Bolts in the past.

[@chargerman426]

To bad this channel seems to have died. This guy had some great tips and helpful videos.

[@dreadknot2238]

Helicoil is still better if you working on small bench engine.

[@snivesz32]

You should compare them to helicoils.

[@paddybugge79]

why not switch to studs ?

[@HotRodHippie]

Why switch? I like the look of bolts better. Studs can break off same as bolts. Studs can arguably be stronger but it’s a header, strength isn’t really a concern.

These inserts are not any stronger than helicoils from the data i have seen. As an Engineer it makes a little sense as the softer material used in these inserts needed to swage the insert into place is its weak point. Helicoils are a harder material. Just my perspective, but enjoyed the video all the same.

[@egx161]

Helicoils can unwind and/or distort. No thanks. Time Serts 100%
