| Pulled mine today . Have a new one on the way . One of the holes has bad threads . It's in the water jacket , of course . Had a bolt wrapped with Teflon tape in it . Anyone know of better fix ? I did order a stud to replace the bolt . Don't wanna pull the head if I can get by . Thanks |

| Try a small amount of hi-temp epoxy and use a release agent on the bolt. Leon |

| Needs to be a stud so it runs out of threads when you screw it in 1/2" and put some kind of dope or Teflon tape on the threads. This is of course as long as someone hasn't oversized the hole in the head from drilling out a broken off stud from a previous repair ???...……. |

You might have to drill it out and use an insert and some high temp sealer. ------------- WD,D15,190XT,7000,8010x2,7060,8070 |

Any kind of epoxy or sealant that can withstand the whopping 15 ft-lbs of torque, should do the job... If the stud pops out, Heli-coil time... ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |

| Checked my book and it says manifold to head torque is 25-30 lbs . Still less than I thought . I'll be happy with 5 lbs and no leak . Thanks |

| Missing 5 out of 8 studs . Have them on the way . Since the second stud from the front is in the water jacket I assume that the next to last stud is too ? Plan to put thread sealer on both . Should the other ones be installed dry ? Maybe a little antiseize ? Thanks |

ACinSC, I had two bad threads in the head on a 45. it was off so went to the shop and he put a new thread insert in each bad spot. This was 1/8 inch larger per side than the thread. I believe it screwed in with sealant and prick punch to lock it. It leaked just a little till the engine cured the sealant and hasnt leaked since. It was more work but saved the head. I used sealer on all the studs when installed. Good luck on your project.

| Anyone know why threaded studs are so expensive ? 5 studs cost me $73 . Guess I should have asked the price before I ordered them . Oh well . Thanks |

Who are you getting them from? I don't think I paid that much for ones from AGCO last time I got some. ------------- If it was fun to pull in LOW gear, I could have a John Deere. If you can't make it GO... make it SHINY |

JB Weld sells a putty type glue for wet areas. It comes in a cylindrical tube. You cut off how much you need and then knead it. it worked great on an oil pan I fixed so it should work for your use. It should also make new threads once it's cured. ------------- D14, D17, 5020, 612H, CASE 446 |

Everyone would like to know who's overcharging for parts. Or is it just AGCO has raised prices on parts they don't want to handle? ------------- If it was fun to pull in LOW gear, I could have a John Deere. If you can't make it GO... make it SHINY |

I would think even the expensive auto parts group, locally wouldn't charge much more than $5 per for those lil studs... ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |
