getting out stuck head studs
I have been helping a couple friends built a hill climb engine. It had 8 stuck studs. They came up with a neat idea how to get them out, with out breaking them. They are Steven Grace and Bill DeVore. They took some 1/2 plastic conduit cut it about 3/4 inch long. Then put it around the stud and glued it to the block. Then filled it with penetrating oil,let it set for a few days. It worked.
They used black RTV Last edited by George Miller; 11-16-2017 at 12:59 PM. Reason: added to |

Re: getting out stuck head studs
I just did this, after all the usual advice, soaked with Kroil over week or two, MAP gas heat , tapping on studs, still broke 5. TIG is the best way, but even then we tried 3 times on one of the long water outlets and no go. I think we found a trick. Modified one of the tools for air hammer, set it on low, then heated around stud and started LIGHT vibration. You could just see the Kroil going right into stud, amazing. Did that a few times and out it came. Patience is the best tool in the box.

Re: getting out stuck head studs
A Friend made a Play-Dough dam around 2 studs & filled them with COKE, overnight. They came out easily????

Re: getting out stuck head studs
I wonder if the black oil resistant rtv would work as a glue... Ive heard of the clay dam before as well. I have a block with stuck in there studs i could try a few things on. Ive always wanted to try the candle wax trick!

Re: getting out stuck head studs
I did the same sort of thing earlier this year.
Made a little dam with modeling clay around each stuck stud and filled with PBBlaster. Renewed as needed. Then double-nutting and they all came out. |

Re: getting out stuck head studs
I soak mine with Kroil for a day or two and then use my stud removing tool with a 24" breaker bar. Sometimes one or two breaks and I let my machine shop take it out.
