I pulled the engine on Henrietta and discovered that there is a hole in the block just above the right side where the flywheel bolts to the block, (the shimmed bolt). It's about a quarter inch in diameter. Is this fixable?

I am assuming that you mean just above the bell housing which is where the flywheel is located. You may want to try some JB Weld but first dry and clean it well with a rotary wire brush on a drill motor. If possible push some into the hole to create a larger glob on the inside to keep it keyed into the hole.
Or, try tapping the hole and put a tapered pipe plug in it.
Some pictures would help.

Irontite tapered plugs would probably be fine
The issue will be if the surrounding material is thick enough to hold the thread

Aloha, thanks for replying. You're sorta right. It's where the flywheel housing bolts to the block. My bad.

Aloha Oldgearz, It was definitely water. As I was poring it in one end it was coming out the other. Thanks for replying.

Aloha Mr. Neilson,
Is Irontite a brand name? Would you also recommend Locktite? Thanks for your reply

Aloha Bra,

These are used in crack repair and I have used them in plugging holes in blocks.
I am afraid that the water jacket back there will probably be very thin due to corrosion internally. That will make the repair hard to do.
I have also used MarineTex epoxy and added a filler of powdered metal with success.
I spent my summers on Maui with Grand Parents as a kid, it took a week to darken up and then I looked local.
Good luck, John

If you do use a tapered pug, tap shallow so that the plug does not go too deep. You can always cut off the end of the plug if it is too long. Use an epoxy like JB Weld as a sealer and to secure the plug. You can cut and grind off the part of the plug sticking out after the epoxy is set but do not get the plug hot or the epoxy will come loose and you may develop radial cracks when the plug expands.
One other idea is to make a small plate to cover the hole and screw it to the block at the sides with machine screws. Make it water tight with JB Weld.
I would still like to see before and after photos.

Thank you one and all for replying. I will give this considerable thought. Not sue how to include a picture.

Please post a picture of the hole.
