I’ve found that putting a copper tube into the hole and feeding your mig wire through that will keep the “nub” from swelling too much and damaging the aluminum threads. The nub feeds into the copper which won’t take the weld. This nub…. Once cooled, can then be welded onto with a nut and run out. The copper tube also makes it so you don’t have to remove the manifold. I just found that easier for me rather than fighting and prying the manifold. Just a suggestion you might want to try. Great video… appreciate you taking the time. 👍🏼
@@dman3962 No I took the manifold off, but the stud was broken off approximately 1/4” below the surface. I didn’t want to corrupt the threads or the deck surface. The copper tube got me past this point without any issues and far enough out so I could get a nut on it. On a few, I didn’t need a nut, I just turned it out with vise grips. I have done this without removing the manifold on pickups, but space is limited on vans. The tube helps on pickups with the manifold on, so it doesn’t stick to the manifold

Wow I just found this out today on my 09 g8.. The rear bolts on both sides snapped in half. I just spent $76 this morning for exhaust repair clamps.. Thanks bro👍.. Subscribed!
You got lucky. I had to weld on mine to to be able to get it out. There is no room in there to have a welding helmet on once you get the fender liner out. I had to get the nut I was going to weld on in position, clos emy eyes, buff it with the welder for a second, open eyes and check. Got it out after trying 17 times.
Awesome. That's the old Mike Yarman trick...! Ain't easy. I broke off 5 bolts in a axle housing and Mike welded nuts to all of em and got em out for me.
Man bro your 7mm ratchet wrench trick did the trick!! Well I broke it loose with se vise grips and used the 7 to back it out. But instead of using the manifold to snug it on I just hit it a few times with a big wrench lol 😆 thanks man

I was just getting ready to do a bolt set! I found a bolt head on the pavement where I park. I've been messing with lifters for a month though, lol. I've had the valve covers off, tryed the B-12 chemtool into the pushrods, flushed the motor with trans fluid, and the exhaust bolts were going to be my next attempt. So thanks for verifying this.
Not sure if you mentioned it in the video or not, but these manifolds do warp on the surface that mates to the head. I have had them machined flat in the past. The last one I did, I didn't want to wait for the machine shop. In the middle of the manifold there is a spot where two bolts are side by side. I made a relief cut in the manifold there so both sides could flex a little. Put it all back together and its been fine for a few months.
Long shot, but I may be dealing with some warpage on one side of my 5.3 manifold. By relief cut, do you mean you made an incision between the middle two bolt holes? How far did you go?
Wow my buddy just told me about this trick after I had already destroyed my head trying to drill out the stud, but thanks for this great how to anyhow. If I have this problem in the future I now know what to do.
I bought a 2005 suburban with 160000 miles for 1000. It was making a ticking noise. The guy says it's 100 percent the lifter, he had it checked by a mechanic. The mechanic quotes him 3800 for DOD removal plus new camshaft, lifters, rockers, valves, springs, and new updated valve covers. I was planning on replacing just one collapsed lifter to get the ticking to stop. I get the car home and pull the valve covers and all the lifters appeared to work fine. I peek down and sure enough about half the exhaust bolts were broken. All four in the rear on both sides were broke. I was able to extract a few and the ones I couldn't I bought three aftermarket clamps that clamp to the block and exhaust so you don't even need bolts. Worked great and been driving it for 3 years no problems. The funniest thing is my suburban does not even have DOD or collapsible lifters lol. I got a nice 4x4 suburban for 1000 dollars and one Saturday afternoon of work.
That's one hell of a deal! I was reading and at first like 05 doesn't have AFM. Then as I read it all made sense. Nice getting it so it didn't sound ridiculous. I know about the clamps just don't like them as a fix because it's not the correct fix. As a shop working on customer cars I won't put one on as it's not professional to do so. I understand it for a personal vehicle though.
I had to weld out 4 studs on my 2002 6.0, 2 fronts and 2 backs it sucked. I got a cheap welder from harbor freight. it was hard because my welds kept breaking off for some reason, but eventually I got it.
Good job make the job a lot easier if you remove the inner Fender Wells that are just held on by plastic tabs especially if you're going to weld nuts onto the broken bolts.
Be sure to check your manifold for cracks mine had a hair line that was caught fortunately. I had 2 broke bolts on each side next to fire wall 4 total 3 of which were broke flush with the head mounting surface and had to replace manifold 600.00 bucks all together at chevrolet. I felt it was worth not having to deal with it if the other bolts decided to break. 2004 6.0 2500hd. ARP BOLTS ONLY!
I would avoid grade 8 because they don't like to stretch. Stainless steel might be a good choice though. But the reality is they do typically last at least a 100k so idk what the best option is without a 100k in testing
Been reading that stainless steel in aluminum is the way to go. But studs with nuts to spare the aluminum threads in the block. Along with high temp anti seize rather than locktite designed for aluminum applications (non copper high temp). Our 2007 Yukon Denali with the 6.2L L92 doesn't have afm which I though might be the cause of some ticking... thinking now I should grab a light and look for black marks around the manifold. Good content.
glad to know that this is common for GM, i am working on a 2003 gmc savana with the 6.0l v8 engine, and i noticed the ticking even when the van is warmed up it still ticks but i noticed when im driving and giving it some gas it goes away but you can still hear it when it idles, suspected symptom of manifold leak? i havent dove very much into yet but will do in acouple days
@@CrazedPerformanceRepairyessirrr you helped me a lot it actually had a few bolts broken from the rear and front on both sides of the engine, since it was the cargo vans the job made it the worst couple days of my fcking life 😂😂 especially when I don’t work on gm too much and being a mobile tech in the heat but hey my pockets were happy after the customer paid side note I think this job showed me that I have potential to be a good yoga instructor 😂😂
That’s the exact bolt that broke on my 2008 Silverado. Dealer told me that it was caused by the head being aluminum and the manifold being cast iron. Tried to sell me the bolt extraction and manifold replacement for 1400. I laughed and did it myself for under 300.
Had the same issue on my pickup. Mine's a 2013 6.0 and at first I thought maybe it was a lifter. After looking around I found the back bolt broken on the passenger side and both the front and back bolts broken on the drivers side.
i just had one of these on each LS head break. one had threads show so i stickwelded a nut onto it and it came out easily. the other was about one thread into the head broke off and i tried mig welded a lump on there to twist out but my lumps twisted off then i tried drilling and using a easy out thats similar but different than yours enough that it had a drill bit inisde and and easy out thing on outside. It did turn almost half a turn but TLDR, it broke off in the hole. so i tried migging a nut on there again and no deal, just twisted off. i do have another ls core i could steal a head from, is that my easiest option at this point? will that involve a new set of intake and head gaskets?
Just took the head off my 07 Tahoe and saw the studs of the bolts on both ends and thought that it was like this from the factory. After watching this video I realize the heads of the bolts have snapped off.
That is most likely a 5.7 with cast iron heads. You will have to drill and extract that bolt. Unless there is some stud sticking out. In which case you could weld a nut on then.
Great job. I've been trying everything to figure out why my 2001 silverado hd has code po300 missfire. To much o2 leaking into exhaust (o2 sensors). Causing rich mixture.
First off, that would cause a (false) lean condition, not rich. Second, the code in that case would be P0171, not P0300. Misfire conditions are detected through the crankshaft position sensor, not the oxygen sensors.
How much did you charge for this, just so I know what to expect when I take it somewhere, people tell me my head is trash if this happens but I know the aluminum shouldn't be affected if ur welding steel
I had my arm/did delete and went with regular lifters and new cam. Now I have that tick and I have some hesitation stutter on acceleration. No codes. Is it possible broken bolts are making me run like crap? Just acceleration is giving me a stutter now.
That could be a lot of things. You may have done something wrong on install, have bad plugs, dirt caught in the MAF or something. Hard to say without proper data.
I had my heads rebuilt and since they went to the machine shop I had them remove the rear broken studs on my 08 Avalanche. I put back new GM studs but wanted to know if you had an idea of what the root cause was and how to prevent it from happening again. Wonder if it was a manufacturing process issue at GM factory that over torqued the rear bolts.
Heat stress over time mostly. However, the bolts are a bit small and weak for the application. So better hardware would make it last longer. Also sometimes the manifold warping over time plays a factor. One could get it resurfaced.
got the same job on a hummer 2, very back bolt on drivers side, had nub sticking out, that broke off, tried welding nub up. no avail, tried plasma cutter, only goes so deep, just a shitty angle,
I just took off my heat sheild after hearing loud engine noise, rattle chirp newr exhaust manifold. I have a turbo engine. There are two bolts broke on the manifold, hopefully they can fix it without removing my turbo. Else they wanna charge me to remove turbo, catalytic converter, manifold and gasket. Something about replacing the gasket with the bolts. What do you think? Should replacing the bolts be easier?
It is best to use stainless but the other bolts are awfully cheap and people don't seem to care much as long as it lasts a while. Considering the stock ones typically last 100,000 miles plus they really aren't that big of a deal to replace.
@@CrazedPerformanceRepair Yeah, sounds reasonable. I just don't like the idea of mucking up a head or using helicoils. Personally, I'd pay you to install stainless. 😉
If You let it warm up at all You will have to let it sit and cool down as well. Otherwise the manifold will be too hot to even work on the thing. It might help though only because it might make it easier to get the weld to stick.
Jesus. I have 1 broken off inside aluminum head! Bought the truck that way.. somebody went to ticket apart and the bolt broke and it still hanging by a little peel of a thread... No kidding!
I'm about to remove two broke bolts on the left side. I'm going to do my best to weld a nut on that back broken bolt. It's super tight in there, so I'm fairly nervous. Lol. Also I did get the replacement bolt set. There isn't an issue on the right side exhaust manifold, but the question I was wondering was, should I remove and replace the old bolts on the right side too?? Before they break? Or is that a risk I shouldn't take, and just leave them alone for now? I'd rather not have them break in the future, but I also don't want them to break trying to remove them, and cause myself unnecessary work. Sigh...
What do you think about using factory bolts but with a nice thick stainless steel fender washer? Would that help dissipate/reduce heat on the head of the bolt??
Nah I don't think it will help much. Better bolts like stainless or ARP will help. But one thing to consider, these always have well over 100k miles before failure. So it's not like it's a short term fix.
@@CrazedPerformanceRepair ok thank you. I’m about to have my 6.2 on my 09 Yukon rebuilt and I want to upgrade a few things. So if I’m going to keep my truck I’m going to replace these bolts now for the rebuild but I’m going to order an extra set of bolts and I’ll change them at 50,000 or 75,000 not a big deal. Thanks for the info, I am not a mechanic I just do what I can when we have an issue and it’s mostly bolt on. 🇺🇸 💪🏻 👊🏻 🤙🏼
Oh my God I dont understand all the hate and smart ass comments lol. You people came here because you obviously have this problem and this guy is cool as hell and shows us multiple ways to help us and yall still bitch and moan. If i was him I'd delete the damn thing and laugh as you all paid a dealership a grand to do this. Thanks for the video man I appreciated it.
Not necessarily, lot of times the studs get in the way. I think the issue it the little 8mm bolts (5/16) vs the old sbc that has 3/8 bolts and doesn't fail.
@@stephenjohnston226 It might but honestly a stainless bolt might be best. Stainless does a good job with lots of expansion and contraction so that might work the best but I'm not sure. Its hard to test because the original ones typically last a 100k miles or more.
Your not going to crack the head with a pry bar it's not brittle it's soft. You might ding it if you get crazy or twist the bar I guess. The torch does same as a welder in regards to heat. It just doesn't add a nut to put a socket on. The heat allows the lock tight to let go.
Have u seen them dorman brackets you bolt on and it snugs up the manifold to the head and boom your done without all the hassle of what you did there????
Yes, but this is the correct way to do it. Besides more often then not you end up with a broken bolt on the front by the alternator bracket. I don't believe those can be used there.
@@CrazedPerformanceRepair your doing right thats a fact you do everything right, I can never thank you enough for your video's on stuck lifters..you sent me the lifter tool and i fixed my lifter and u saved me thousands in repairs. Love your videos there so informative and you show everything from start to finish thanks for sharing
It does, your upstream 02 sensor on that side will tell the computer it's running lean because the exhaust is escaping before the o2 sensor and the computer will then start dumping more fuel. You'll get PO300 misfire codes and then eventually PO171 system lean bank 1. MPG will nosedive and black soot out the tailpipe.
Absolutely. I had a exhaust manifold leak on both sides and the truck tried to compensate by adding more fuel, she ran like total shit because the o2 sensors started to “foul” i guess. New 02 sensors, new exhaust bolts and gaskets, and new plugs has her running smooth again.
Curious would this be something I should do myself or Maybe take it to my local performance exhaust shops to have the work done? Was planning on swapping the manifold’s with headers.
Wow. Looks like a nasty job! My 6.0 has this. Started out as a whistle almost like a bearing somewhere such as serp pulley. Bolts missing in 4 areas on manifolds. Think I'm gonna go with the band aid brackets for now....
I believe that has a cast iron cylinder head, if so you will need to drill a bunch of small holes with high speed bit around the bolt and extractor. Then you need something like a time-sert amzn.to/33GK50h otherwise you could try to blow out the extractor with a cutting torch if you are skilled enough with a torch good luck.
Like an idiot I had both of my heads off recently replacing lifters, trays, cleaning tops of pistons, heads, new springs, rocker trunion upgrade, etc. Well while I had the driver side head off I forgot that the stock manifold on that side had a broken rear bolt and I overlooked it and installed the head without removing it. Now I have to hop I can get it out without having to remove the head again since I put on long tube headers. 🤦♂️🤦♂️🤦♂️
@@stiffmeister0hYeah which bolt is it and what head casting is it? Is it an LS head? Go on Ebay and look up the KAP manifold bolt repair kit and find the one for your head. It states in the listing description what bolts each one will fix. Simple design and it works.
i’m getting it done right now and getting headers put on and with header install, exhaust install, and bolt removal it is $1,500. I don’t have the price just for the removal yet until i get my truck back
I haves noise on my ram that scares me. Brand new build NON-MDS 392 Stroker. Sounds like header leak but i can’t find any smudging anywhere. BBK headers, could there be a crack somewhere?
Going about it all wrong. Remove wheel. Remove inner fender. Give each bolt head a good smack. Remove manifold. Weld larger nut to the broken stud. Remover stud. If bolt is broken flush build up a bead of weld on it then weld nut to bead. Easy stuff
@@CrazedPerformanceRepair Hmm.. I'm sure you are correct, I'm a weekend warrior. However, yesterday I removed the factory exhaust manifold gaskets on my '03 Tahoe and I've got 9 (of 12) 10mm bolts to show for it. I just put a caliper to the head of one of these ICT Billet exh manifold bolts I'll be using and sure as shit, they've got a 10mm head as well. I'm sure I'm confused about something tho..
@@randykudijaroff482 someone prob swapped them in there as maintenance in hopes to prevent breakage lol. We can clearly see how well that worked out...
@@randykudijaroff482 they all seem to break with time, stainless does seem to last in the high performance stuff but then again that's header's not manifolds so the expansion rate prob plays a factor.
Aluminum heads steel bolts, but that's not the issue. Notice there was no corrosion on the threads? That's because they use locktight on the threads so corrosion isn't the issue it's the small diameter bolts with lots of expansion contraction cycles not able to handle it long term.
@@CrazedPerformanceRepair yeah I see your point for the burried threads but the bolt heads pop off too and aren't those portions corroded some? From what I'm gathering maybe the main point some of you guys are making is that the bolts will die from heat cycles before they corrode.
So how serious is this issue if not taken care of? I have the bolt broken off showing no threads on the driver side furthest back closest to the firewall. Think it is a small exhaust leak and no sensors going off and very faint noise. Can this destroy the motor, or the motor, cause total engine failure at some point? How serious is it in should it be a major priority getting it fixed ASAP?
Exhaust leak will cause motor to run rich (injectors putting in too much fuel). The engine will run poorly, it will quickly destroy catalytic converter, foul the plugs causing misfires, and gas will get in oil destroying lubrication. It eventually will destroy engine if not addressed.
just got a truck with 80k miles on it and one of the bolts is broken off... idk if someone tried to get it off before and snapped it then gave up or it jsut happened by itself but damn is that a bitch...
Not when the bolts are cracked due to the numerous heat cycles they go through. It'll help the stuck unbroken bolts but not those putters that 9/10 times break or are broken by the time you hear the puffing.
Also it's the lock tight holding it in not rust or corrosion so in those cases penetrating oil won't help. Hmm wonder if a lock tight desolver exist yet? New product idea perhaps
@@animalcorvair I get that, but the lock tight melts when you heat it. That is why it comes out easy after using a welder, the welder heats it so fast it can melt the lock tight deep within the head. I don't think I have ever seen any sort of corrosion inside the head on these yet. I believe it is because the lock tight used actually seals off the water and what not from getting in there to cause a problem in the first place.

why i am keeping my 92 k1500 350 ,,my son inlaw has had two chevys with the 5.3,,junk bolts in both
Great repair but you almost dropped that bolt down into the exhaust pipe ;)
I thought sure as shit he did, my luck I would have. Lol
i just had one of these on each LS head break. one had threads show so i stickwelded a nut onto it and it came out easily.
the other was about one thread into the head broke off and i tried mig welded a lump on there to twist out but my lumps twisted off then i tried drilling and using a easy out thats similar but different than yours enough that it had a drill bit inisde and and easy out thing on outside.
It did turn almost half a turn but TLDR, it broke off in the hole.
so i tried migging a nut on there again and no deal, just twisted off.
i do have another ls core i could steal a head from, is that my easiest option at this point? will that involve a new set of intake and head gaskets?
My 05 2500hd has been doing this for years. I thought it was lifters until I went searching and found 2 broken bolts on the passenger side #8
Just took the head off my 07 Tahoe and saw the studs of the bolts on both ends and thought that it was like this from the factory. After watching this video I realize the heads of the bolts have snapped off.
Yes, I have a 88 Chevy 88Z 71 with a broke manifold boat in the very back only driver side I don’t know how to get it out without pulling the motor
That is most likely a 5.7 with cast iron heads. You will have to drill and extract that bolt. Unless there is some stud sticking out. In which case you could weld a nut on then.
@@CrazedPerformanceRepair thank you boss
Great job. I've been trying everything to figure out why my 2001 silverado hd has code po300 missfire. To much o2 leaking into exhaust (o2 sensors). Causing rich mixture.
First off, that would cause a (false) lean condition, not rich. Second, the code in that case would be P0171, not P0300. Misfire conditions are detected through the crankshaft position sensor, not the oxygen sensors.
Well done buddy
How much did you charge for this, just so I know what to expect when I take it somewhere, people tell me my head is trash if this happens but I know the aluminum shouldn't be affected if ur welding steel
It's typically a day worth of work so expect 4-8 billed hours worth of labor.
lol I have more than half broken on my truck. Crossing my fingers that they aren't broken off in the head.
Do you have to replace the gasket too? Or is it recommended?
Yes, you should replace the gasket.
@@CrazedPerformanceRepair THANK YOU :)
Have exact issue on my 2007 suburban…..guy wants 800 for 2 bolt repairs…extra 150 if bolt breaks and he has to weld, is that reasonable?

If you have an older, 2009 5.3 and no broken bolts, would you recommend changing them out? If you are in there anyway?
I had my arm/did delete and went with regular lifters and new cam. Now I have that tick and I have some hesitation stutter on acceleration. No codes. Is it possible broken bolts are making me run like crap? Just acceleration is giving me a stutter now.
That could be a lot of things. You may have done something wrong on install, have bad plugs, dirt caught in the MAF or something. Hard to say without proper data.
Why does Chevy have these broken exhaust bolt issues? I will use the spline wrench method. I tried the vise grips but that is tough.
I was worried you were about to drop that hot stud into the exhaust pipe!
I have a 2000 GMC Yukon Denali and its making the same sound when I start it up. I wonder if this is the same problem with mine?
Go look and see if the head of any bolts are missing and you’ll wonder no more
I had my heads rebuilt and since they went to the machine shop I had them remove the rear broken studs on my 08 Avalanche. I put back new GM studs but wanted to know if you had an idea of what the root cause was and how to prevent it from happening again. Wonder if it was a manufacturing process issue at GM factory that over torqued the rear bolts.
Heat stress over time mostly. However, the bolts are a bit small and weak for the application. So better hardware would make it last longer. Also sometimes the manifold warping over time plays a factor. One could get it resurfaced.
got the same job on a hummer 2, very back bolt on drivers side, had nub sticking out, that broke off, tried welding nub up. no avail, tried plasma cutter, only goes so deep, just a shitty angle,
I just took off my heat sheild after hearing loud engine noise, rattle chirp newr exhaust manifold. I have a turbo engine. There are two bolts broke on the manifold, hopefully they can fix it without removing my turbo. Else they wanna charge me to remove turbo, catalytic converter, manifold and gasket. Something about replacing the gasket with the bolts. What do you think? Should replacing the bolts be easier?
i put studs back in mine
good idea 👍
Why not use A-4 stainless steel header bolts? They're less likely to break and/or rust weld to the header.
It is best to use stainless but the other bolts are awfully cheap and people don't seem to care much as long as it lasts a while. Considering the stock ones typically last 100,000 miles plus they really aren't that big of a deal to replace.
@@CrazedPerformanceRepair Yeah, sounds reasonable. I just don't like the idea of mucking up a head or using helicoils. Personally, I'd pay you to install stainless. 😉
these head bolts on gm trucks break since the start of the c series.1976-2000 in my experience
Should I do this when the motor is cold or let it warm up for a little..
If You let it warm up at all You will have to let it sit and cool down as well. Otherwise the manifold will be too hot to even work on the thing. It might help though only because it might make it easier to get the weld to stick.
What size welder did you use ? Would a small buzz box work ? Or do I need a 220v for the heat
You can get it with a small buzz box but crank it up and it may take a few tries.
Would this cause the oil pressure to go up every time I accelerate or that is just a separate problem?
totally separate and normal with a working gauge.
Jesus. I have 1 broken off inside aluminum head! Bought the truck that way.. somebody went to ticket apart and the bolt broke and it still hanging by a little peel of a thread... No kidding!
I'm about to remove two broke bolts on the left side. I'm going to do my best to weld a nut on that back broken bolt. It's super tight in there, so I'm fairly nervous. Lol. Also I did get the replacement bolt set. There isn't an issue on the right side exhaust manifold, but the question I was wondering was, should I remove and replace the old bolts on the right side too?? Before they break? Or is that a risk I shouldn't take, and just leave them alone for now? I'd rather not have them break in the future, but I also don't want them to break trying to remove them, and cause myself unnecessary work. Sigh...
They are most likely broken or just about to break. You just can't tell because they are hardly hanging on.
What do you think about using factory bolts but with a nice thick stainless steel fender washer? Would that help dissipate/reduce heat on the head of the bolt??
Nah I don't think it will help much. Better bolts like stainless or ARP will help. But one thing to consider, these always have well over 100k miles before failure. So it's not like it's a short term fix.
@@CrazedPerformanceRepair ok thank you. I’m about to have my 6.2 on my 09 Yukon rebuilt and I want to upgrade a few things. So if I’m going to keep my truck I’m going to replace these bolts now for the rebuild but I’m going to order an extra set of bolts and I’ll change them at 50,000 or 75,000 not a big deal. Thanks for the info, I am not a mechanic I just do what I can when we have an issue and it’s mostly bolt on. 🇺🇸 💪🏻 👊🏻 🤙🏼
Oh my God I dont understand all the hate and smart ass comments lol. You people came here because you obviously have this problem and this guy is cool as hell and shows us multiple ways to help us and yall still bitch and moan. If i was him I'd delete the damn thing and laugh as you all paid a dealership a grand to do this. Thanks for the video man I appreciated it.
A grand would be a good deal..
Would it be better to install studs with bolts on the head instead of the factory bolts
Not necessarily, lot of times the studs get in the way. I think the issue it the little 8mm bolts (5/16) vs the old sbc that has 3/8 bolts and doesn't fail.
Do you think a good arp bolt would fix this problem?
@@stephenjohnston226 It might but honestly a stainless bolt might be best. Stainless does a good job with lots of expansion and contraction so that might work the best but I'm not sure. Its hard to test because the original ones typically last a 100k miles or more.
Thanks crazed performance repair really enjoyed your videos. Really wish there was more mechanics that cared around. Keep it up.
What's the grade of those bolts? Doing all that work you should just put on headers right away....
Lower grade I'm sure because high grade like grade 8 don't like to be cycled so much
After you remove the broken bolt , do you have to replace the manifold? Or just new bolts gaskets and good to go?
Typically just new bolts and gaskets.
Yipes, putting a pry bar against that aluminum head?? And heat all bolts with acetylene torch before trying to remove.
Your not going to crack the head with a pry bar it's not brittle it's soft. You might ding it if you get crazy or twist the bar I guess.
The torch does same as a welder in regards to heat. It just doesn't add a nut to put a socket on. The heat allows the lock tight to let go.
Have u seen them dorman brackets you bolt on and it snugs up the manifold to the head and boom your done without all the hassle of what you did there????
Yes, but this is the correct way to do it. Besides more often then not you end up with a broken bolt on the front by the alternator bracket. I don't believe those can be used there.
@@CrazedPerformanceRepair your doing right thats a fact you do everything right, I can never thank you enough for your video's on stuck lifters..you sent me the lifter tool and i fixed my lifter and u saved me thousands in repairs. Love your videos there so informative and you show everything from start to finish thanks for sharing
Tell me, do broken bolts affect the oxygen intake? Can it be that the engine is unstable? If one bolt on each side is broken off?
It does, your upstream 02 sensor on that side will tell the computer it's running lean because the exhaust is escaping before the o2 sensor and the computer will then start dumping more fuel. You'll get PO300 misfire codes and then eventually PO171 system lean bank 1. MPG will nosedive and black soot out the tailpipe.
Absolutely. I had a exhaust manifold leak on both sides and the truck tried to compensate by adding more fuel, she ran like total shit because the o2 sensors started to “foul” i guess. New 02 sensors, new exhaust bolts and gaskets, and new plugs has her running smooth again.
How did you hold the nut while you welded it
I usually just use a pliers.
The sad part is you tossed the mls gasket for the pos felpro junk. You’ll be replacing that gasket again.
Do you prefer straight grip or curve grip vice grips?
Yes, in most cases.
Curious would this be something I should do myself or Maybe take it to my local performance exhaust shops to have the work done? Was planning on swapping the manifold’s with headers.
Depends on your skill level
Wow. Looks like a nasty job! My 6.0 has this. Started out as a whistle almost like a bearing somewhere such as serp pulley. Bolts missing in 4 areas on manifolds. Think I'm gonna go with the band aid brackets for now....
my problem is the bold broke off inside the motor And the bolt extractor broke off inside it too. 1995 chevrolet g 20 van
I believe that has a cast iron cylinder head, if so you will need to drill a bunch of small holes with high speed bit around the bolt and extractor. Then you need something like a time-sert amzn.to/33GK50h otherwise you could try to blow out the extractor with a cutting torch if you are skilled enough with a torch good luck.
I have a GMC Sierra and recently found two bolts broken, can this make the check engine light come on?
Yes it can throw a O2 sensor code.
Would that cause a misfire also
No
So what happens when you've tried to remove one below the surface with a tap and it breaks off?
Lots of swearing, then attempt tap extractor and end with a welder. That's why I try not to use a tap if I can help it lol.
been there done that 40 years ago nothing new here for me also didn't have you tube too, but some one can learn or ALSO weld a net on and back it out
may i ask will this cause misfire or slight rough idle? since i hear the same thing
Might cause rough idle if it's messing with o2 sensor reading.
@@CrazedPerformanceRepair thank you watch ur vids cuz of the DOD. from the Philippines
Like an idiot I had both of my heads off recently replacing lifters, trays, cleaning tops of pistons, heads, new springs, rocker trunion upgrade, etc. Well while I had the driver side head off I forgot that the stock manifold on that side had a broken rear bolt and I overlooked it and installed the head without removing it. Now I have to hop I can get it out without having to remove the head again since I put on long tube headers. 🤦♂️🤦♂️🤦♂️
If I can't weld and have the bolt broke INSIDE the head, do I have to pull the head off to fix? This sucks...the second bolt I can get vice grips on
@@stiffmeister0hYeah which bolt is it and what head casting is it? Is it an LS head? Go on Ebay and look up the KAP manifold bolt repair kit and find the one for your head. It states in the listing description what bolts each one will fix. Simple design and it works.
@@JustAGuy781 it's the rear drivers side Escalade 6.0. Snapped inside the head.
@@stiffmeister0hYeah

@@JustAGuy781 yep save alot of cussing
This happen to my crystler Aspen
Any clue what the cost would be to get a shop to do it?
Depends on labor rate and how the tech does the job.
i’m getting it done right now and getting headers put on and with header install, exhaust install, and bolt removal it is $1,500. I don’t have the price just for the removal yet until i get my truck back
300 plus 1 hour labor per broken bolt. Some mechanics say they have to take head off. But I didn't neither did this guy.
Thanks for the video! One more confirmation for why I will not purchase from a manufacturer who refuses to address a known issue aright.
lol I guess your still walking than huh!
@@trev1481 Good point and well-taken.
Rephrase: I try to stay with manufacturers who think long-term. Perfect? Nah, but healthy companies.
I haves noise on my ram that scares me. Brand new build NON-MDS 392 Stroker. Sounds like header leak but i can’t find any smudging anywhere. BBK headers, could there be a crack somewhere?
Sure could be, hook a vacuum cleaner exhaust to tail pipe and check for leaks with soapy water while it's cold
Going about it all wrong. Remove wheel. Remove inner fender. Give each bolt head a good smack. Remove manifold. Weld larger nut to the broken stud. Remover stud. If bolt is broken flush build up a bead of weld on it then weld nut to bead. Easy stuff
man i would totally pull the motor to do that...
That would add 5 more hours to the job and alot more work
Lol
@@TheWolverine-rm2kr did it today (after writing that comment). Lifters and a new oil pump will be here on Tuesday.
Where is your shop located
In process of moving to Avon SD.
13mm?? I swear I just took 9 of the 12 bolts out and I used a 10mm. I used a mig welder for the other 3.
Someone put the wrong bolts in yours or something. They are all 13mm heads from factory. The aftermarket dorman ones are 12mm odd balls.
@@CrazedPerformanceRepair Hmm.. I'm sure you are correct, I'm a weekend warrior. However, yesterday I removed the factory exhaust manifold gaskets on my '03 Tahoe and I've got 9 (of 12) 10mm bolts to show for it. I just put a caliper to the head of one of these ICT Billet exh manifold bolts I'll be using and sure as shit, they've got a 10mm head as well. I'm sure I'm confused about something tho..
@@CrazedPerformanceRepair I was told if I like pulling busted exhaust manifold bolts to keep using the Dorman bolts..
@@randykudijaroff482 someone prob swapped them in there as maintenance in hopes to prevent breakage lol. We can clearly see how well that worked out...
@@randykudijaroff482 they all seem to break with time, stainless does seem to last in the high performance stuff but then again that's header's not manifolds so the expansion rate prob plays a factor.
Did any of you happen to have missfires with this problem ?
im currently having this ticking noise problem too and i also have constant misfires and rough idling on my 2018
@@chrism.9497 DOD most likely for yours
So is this from an aluminum block with steel bolts? There a hardened aluminum stud/nut or bolt with washer to isolate the two metals apart?
Aluminum heads steel bolts, but that's not the issue. Notice there was no corrosion on the threads? That's because they use locktight on the threads so corrosion isn't the issue it's the small diameter bolts with lots of expansion contraction cycles not able to handle it long term.
@@CrazedPerformanceRepair yeah I see your point for the burried threads but the bolt heads pop off too and aren't those portions corroded some? From what I'm gathering maybe the main point some of you guys are making is that the bolts will die from heat cycles before they corrode.
So how serious is this issue if not taken care of? I have the bolt broken off showing no threads on the driver side furthest back closest to the firewall. Think it is a small exhaust leak and no sensors going off and very faint noise. Can this destroy the motor, or the motor, cause total engine failure at some point? How serious is it in should it be a major priority getting it fixed ASAP?
Exhaust leak will cause motor to run rich (injectors putting in too much fuel). The engine will run poorly, it will quickly destroy catalytic converter, foul the plugs causing misfires, and gas will get in oil destroying lubrication. It eventually will destroy engine if not addressed.
I got 1 broken bolt. Will not fixing cause more to break?
8mm doesn’t come close to manifold bolts on my 2007 Escalade..
The bolt is 8x1.25 thread, the head is stock 13mm aftermarket 12mm, and to extract the exposed broken I use spline drive 7mm and hammer it on.
@@CrazedPerformanceRepair good call
Will a regular 12 point ratchet wrench work or does it have to be a spline wrench
The spline will bite better but you might be able to get it with a 12 point.
just got a truck with 80k miles on it and one of the bolts is broken off... idk if someone tried to get it off before and snapped it then gave up or it jsut happened by itself but damn is that a bitch...
Had given up on GM vehicles long time ago as their engineering has become cut and paste.
More common on late model dodge rams....
And late 90s Dakotas...
Why not just run the engine for a few minutes
pb blaster would help
Not when the bolts are cracked due to the numerous heat cycles they go through. It'll help the stuck unbroken bolts but not those putters that 9/10 times break or are broken by the time you hear the puffing.
Also it's the lock tight holding it in not rust or corrosion so in those cases penetrating oil won't help. Hmm wonder if a lock tight desolver exist yet? New product idea perhaps
@@CrazedPerformanceRepair i understand it was but after you heated it up then used it,,just a thought
@@animalcorvair I get that, but the lock tight melts when you heat it. That is why it comes out easy after using a welder, the welder heats it so fast it can melt the lock tight deep within the head. I don't think I have ever seen any sort of corrosion inside the head on these yet. I believe it is because the lock tight used actually seals off the water and what not from getting in there to cause a problem in the first place.
@@CrazedPerformanceRepair yep locktight does that gm never used that on my older cars
