My old 1967 MGB GT has been surprisingly easy to take apart with virtually no frozen bolts or studs to deal with. Certainly a few cans of PB Blaster didn’t help but from what I’ve read I must be one of the luckiest old car owners in the world.

So far I have only has 2 main issues. One is the bolt that connects the A-arm to the kingpin which I likely will have to cut away. The other is one of the cylinder head studs on the 18V engine. A few months worth of PB Blaster and the usual double nuts did nothing. Time to get serious!

I next tried to heat the bolt a few times and for added measure let some wax get sucked into the hole. No luck again. The damn stud just doesn’t want to come out. Two engines, 22 cylinder head studs and 1 that just won’t budge!

Here’s a nicely exposed photo of adding wax to the stud hole.

Time to get serious. I first tried to grab the stud with vice grips but this just scratched up the stud and nothing happened. At this point I’m hoping I don’t snap this old chunk of metal. Next I ground some groves into the stud so the Vice Grips could get a better hold. All I manged to do was round over the stud even more and lock the Vice Grips to the stud. Another pair of Vice Grips was required to remove the first set.

I wish I had a photo of my final attempt. I used a BF pipe wrench that is about the size of the engine. Very slowly the stud began to turn and as you can see finally came out. Should I reuse this twisted piece of metal? Probably not! I’m wondering whether one has to replace all the head studs or if only one is needed.

Adding wax to the stuck MGB Cylinder Head Stud, I think I'll be replacing this!
