One way to help center a drill bit on uneven broken stud is to use a punch. Take your time getting the hole centered. Punch drill, punch, drill...The punch also has the side effect of loosening the threads in the head. I always get some PB blaster or equivalent on there to soak before starting the process.
Thread size should be the same in the head as on the exposed threads. You can use a nut from holding on the flange to see what the size is. Maybe M8 x 1.25 (post 22 this thread) Last edited by Thumper; 12-16-2021 at 12:40 PM. |

I think "all-thread" at big box stores is actually zinc. I used 1/4" all-thread to replace battery clamp rods in a tractor. Anything requiring actual torque would fail!

They're zinc plated. Definitely steel. Mild steel for sure, but still. A magnet will tell you. You're right in that a solid zinc piece of allthread wouldn't stand up to... much of anything, really. It'd make a bitchin' high surface area electrode for zinc plating other things, though! |

Is it possible to cut a slot using a diamond cutoff wheel in a Dremel? Then use a flat screwdriver to remove the old stud. Just a thought.

Good place to source studs https://www.belmetric.com/m8x125-coa...d-c-9_71_1840/
Just match the length dismensions to what you have.

I've had pretty good luck using left hand drill bits. The studs will usually come out while drilling into them.

Hey so I tried getting them out and just basically got nowhere. Drilled the hole, tried to remove it, didn't work. Tried to drill it out and thread it, also didn't work. I got a new cylinder head. I figured out their m8 x 1.25 studs and got replacements too. Turns out the intake is a different size. Can someone let me know the intake bolt size and thread pitch? Is it m6? Im not sure. I assume it's standardized.

You can take a guess and buy a couple of metric bolts and see if they fit. Or just break down and buy a thread gauge like this one.
These things are SOOoo useful to have.

Intake bolts are an M6 bolt by 20mm long. I just can't remember the thread pitch with confidence, but I believe it is just a 1.0 ( aka M6x1.0x20 )
