I have a exhaust manifold that has several broken studs, so there are many methods on removing them. time to put them to the test and see what works better than others,

    If they ever bring back shop class in schools...this is the video to teach from...! For the beginner and for the seasoned ...pro..it's a great video to watch...

    I wanted to say thank you, yesterday I replaced the wheel bearing in my 2015 E-Golf that was "growling", I would have never had the confidence to have attempted the repair myself without watching your videos over the years. You have also taught me a ton about Volkswagens and I am restoring my 68 vw double cab right now, as well as my 79 westy. Metal work and all. Thanks Darren I have learned so much from you.
  • Any Youtuber can show how to remove broken studs/bolts when nothing goes wrong. and they have a Mill and Carbide Tools as backups. Only Mustie cam show you everything that does go wrong, yet still end up with a working fix with what you have in the home shop. Way to go!
  • I did 13 years as an aircraft machinist in the Air Force. Our primary job was to remove stuck or damaged hardware and repair damaged threads. Sometimes, the head would just pop off or the part twisted or moved, so the bolt broke. One time, I used the eraser on a #2 pencil to spin the broken bolt out. Once. You had to find how the bolt got broken, was it found gone, did it break trying to get it out, or did it break going in? The last 2 you might as well forget the extractor and grab the drills. A lot of our hardware were exotic metals that hardened when they broke. If you center punched them it made them harder. For the 1/4 inch and under we used carbide rotary files and just carved them out. If you don't want to break a drill off you REALLY DON'T want to break an extractor. You REALLY, REALLY DON'T want to break carbide. The manifold bolts in the heads of my truck were so hard a drill would not even mark them. It was a long slow slog taking those bolts out. Yes the heads were still on the engine in the truck. It SUCKED! A lot of the time we were the end user for a part. If we couldn't repair the threads or remove the bolt, the part by regulation had to be sent back to the manufacturer or our depot. Either way, the part came off our inventory and had to be replaced. We were really insulted if that happened. That was your taxpayers money we couldn't save. Aircraft parts, especially weapons and delivery systems were not allowed repairs of any kind. Some parts were classified and you got to have CLOSE scrutiny doing your work. Try getting a stuck screw out with three security police holding weapons at ready. These guys were more nervous than I was! They weren't helping things. I told them to back off just a tiny bit.... LOL! Aircraft parts, even the bolts are expensive. We took our job seriously and tried our best not to waste your money. Out in the real world I used to TIG weld balls of metal to the end of broken taps. MIG welding didn't transfer the heat well and they just broke off. It's not for the novice or inexperienced. You can make things worse, fast. Even with all my experience things still kicked my ass. Like the exhaust bolts. There are many other specialized ways to remove these disasters but it requires equipment you normally don't have at home. Musty, you did fine. I have broken many taps and easy outs in my 47 year career. The big thing is you can only call yourself to get it out. There isn't anyone going to come to your rescue. Except me. I'm too expensive and much too old anymore. My number is unlisted......LOL! Cheers Terry

    I hate those easi-out extractors - breaking one of those off in the hole is much worse than breaking a tap - easi-outs are much more solid than a tap, thus so much harder to break out of the hole. Years of experience pretty much led me to how you do it, drill it out. Knowing how to work the drill bit to recentre the hole is something that comes with practice. Great to see people like yourself passing knowledge like this along.
  • I've had really good luck drilling down into the center of the stud or bolt then welding a nut on It gives the weld more area to grab on to Appreciate the great videos 👍
  • Life is Good. Going to school here and having the greatest teacher Mustie1. I really enjoy this different type of video. I like them alll. What a GREAT channel Mustie1 thanks
  • @ronjones1077
    Can’t believe I spent an hour watching this, but you did it again with a very informative “how to” video! Thank you
  • @rmck6830
    Can't believe I spent an hour watching you remove studs, yet you made it entertaining. Thanks Mustie.

    Thanks for the misery (memories). At 15 (60 yrs ago) I managed to break off a valve cover bolt in a 2.4l I-6 Ford. I learned quickly that I didn't know as much as I thought I did. Thanks to you I'm still learning. Narragansett Bay

    Mustie translated means Determination, Tenacity and Patience. Learned a lot watching this,

    Removing nut/ screws is an art. In the aviation world I have seen removal of counterscrews by drilling off center towards the side and using a punch to tap it loose & back the hardware out. Rich USAF 81-85
  • I have been a mechanic and machinist for over 40 years. What I watch you do and say today was just unbelievable. I have followed you for over five years and have picked up some good ideas and alternative ways to work a task. I have not always agreed with some of your technics but today was on a hole new level of shade tree B/S. I could not even finish watching it. SMFH
  • @StevenEverett7
    I remember way back when, the first time I ever used a tap. I knew that I had to clear the chips. As you started tapping the threads my memory went back to that first time.. as the saying goes " Deja vu all over again." 🤣🤣🤣
  • @garygronborg8154
    I wish I had this learning 40 years ago. And here I am, still learning from Mustie. Many thanks!
  • @PaulGadoury
    This was a good one Mustie !, because snapping a bolt means end of project for lots of ppl.
  • @Ike-i5t
    I've seen people heat up the manifold then use freeze off on the stud. 60% of the time. It works every time. Great video😁😀🤣😎
  • @craigwalker4211
    Alot of us are rushing when met with this situation so can end up with the problem escalating so it's good that you show this stuff to us impatient people.
