Steve Mutter Posted April 8, 2012 Share Posted April 8, 2012 I have one with broken bolts and a bad leak. This is my first leaking manifold on a 6.4 and it is customer pay. I have read that it is a pain in the ass and that some people lift cabs to do this. Do you have to lift the cab or can it be done through the wheel well. Just wondering what you guys have been doing.

Brad Clayton Posted April 8, 2012 Share Posted April 8, 2012 No need to take the cab off for left or right manifolds. Quote Link to comment Share on other sites More sharing options...

Keith Browning Posted April 8, 2012 Share Posted April 8, 2012 He's no fire fighter. He just likes to play with the siren... and his hose. Besides that he is right. Just take the fender wells out and you have access, though that silly EGR cooler is in the way on the left side. Quote Link to comment Share on other sites More sharing options...

Alex Bruene Posted April 8, 2012 Share Posted April 8, 2012 Right side is easy. Even easier when you have a guy you can call in that can get the broken bolts out with the manifold still installed! Quote Link to comment Share on other sites More sharing options...

Aaron Posted April 8, 2012 Share Posted April 8, 2012 Nope. We had one of them in Windsor too. I watched him get a stud out of a 5.4 3v 05 F-series, with the manifold on. he DID drill into the water jacket, but he did get the stud out!

Alex Bruene Posted April 9, 2012 Share Posted April 9, 2012 This guy (somehow) welds a stud on to the broken bolt and spins it out with the manifold still installed. He won't tell anybody what kind of rod he uses and takes the removed piece with him... perhaps so you can't see what the "stud" he welds on to the broken bolt actually is.

Aaron Posted April 9, 2012 Share Posted April 9, 2012 I've done that before, it works well if the busted off piece turns in the head. I weld a short piece of rod with a "t" on the end of it first. Use a hex shaped rod, so if the T doesn't turn, you can cut it off with a whizzy-wheel and put a 5mm socket on it. You need to use a softer steel, and get the welder as hot as you can.

Steve Mutter Posted April 10, 2012 Author Share Posted April 10, 2012 Well, that job was not all that bad. The hardest part was welding a nut on the broken stud. I am just not that good with the mig welder. Need more practice Quote Link to comment Share on other sites More sharing options...
cbriggs Posted April 11, 2012 Share Posted April 11, 2012 I worked with an older guy years ago, that swore by an arc welder for removing broken studs. If stud was broken off flush, he would hold a large nut over the hole where the stud was broken off flush. Then he would jam the arc rod into the broken stud, start the puddle and then fill the nut with weld. Let it cool for a while and they always spun right out. I actually used it successfully a few times, untill I burnt my arm badly when the puddle fell out of the nut and landed on my arm. The problem is now, not much we work on would have room for access with an arc welder. Quote Link to comment Share on other sites More sharing options...
djmiller Posted April 11, 2012 Share Posted April 11, 2012 I've extracted 6.4 broken manifold bolts with the head still on. Problem is the first one the gasket had a hole blown through it, so when I put the new bolt in, it still pissed and whistled anyway... oh well. At least I proved I could do it.

Matt Saunoras Posted April 12, 2012 Share Posted April 12, 2012 I use my mig to pull exhaust studs almost on a regular basis. I don't weld a nut though, I build the stud back up and get a 5/16 or 1/4 extractor over it and walk it out. It takes time to perfect but it works better than anything. I had some slag land in my shirt pocket last week too (stupid I know). I've got a nice burn about an inch away from my nipple right now. It burned through a bank receipt and 3 dollars I had in my pocket. I didn't tell you guys the story of how I got my 03 turbo. The short version is a good core was turned in with the rear bolt broken off. I pulled the bolt out with the mig and the turbo is on my truck as we speak. I bought a totally junk 03 core off a guy I know for $50 and handed that in to parts. Quote Link to comment Share on other sites More sharing options...
