I have an issue with a bolt on one of the cylinder heads on one boat
engine I have. I need to swap cylinder heads on the boats, and the
donor boat is fighting me tooth and nail.

The problem is that 1 bolt will not come off. It's towards the bottom
of the engine (I had to take off part of the engine cover part) and no
matter what I do (vice grips, socket, soak it with liquid wrench)
nothing will budge this thing.

Any suggestions? I can provide pictures to better explain where the
bolt is.


Check out this very cool tool. It's saved me a few times over the years.
Home Depot might carry them, but good luck getting one of their idiots on
the phone to go check for you. Try tool specialty stores, plumbing supply
places, etc.

I've got a whole set commonly called easy outs! But in his case it
sounds like it hasn't broken off flush, yet!


It may still work, though. If he drills deep enough into the bolt, most of
the turning force would be within the shaft, not the head of the bolt.

And what happens a lot is just the drilling into the shaft loosens the
bolt some from vibration. As someone else has posted here, it also
helps to heat the portion of metal that is surrounding the bolt.
Thermal expansion is your friend!
