Belzona, that's some kind of moisturizing facial creme isn't it?

Good luck, hope the rest of the engine is good

Hope your skills are good too

When you think about it, it may not be the textbook best surefire way to cure your problem, but what do you have to lose except a little time and money on that expensive face cream.

Once again.................good luck

Your cooling system sees about 20 psi at high rpm's, just so you have an idea of the pressure involved.

Don't forget, cleanliness and preparation is the key.

And....................There's no H after the preparation

Well, actually preparation H makes for a good face cream. It has properties that shrink the bags under the eyes. So... I don't actually have a point. But, yes, I've nothing to lose. Might use a cheaper option to perform the miracle. Info on the pressure is valuable. I see the port on the timing cover is blocked. Can you describe the water's path through the engine from intake to exhaust?

Take a few minutes and read up on lock n stitch products.
I have seen first hand how well they work putting cast iron back together .
They repair thousands of engines per year. Most are commercial applications in very expensive equipment.
You drill a hole though your crack, insert their plug and then screw a special bolt into their plug. As you tighten the bolt it sucks the crack area tight and then snaps off leaving a flush surface.
Sounds odd but is proven technology. There must be Utubes of it being applied..
I first saw it almost 30 years ago.

Mark,
I have first hand experience with the Lock n Stitch and don't feel is a good option at this time. It's too much work and cost considering there's the unknown of other block damage

I'm not sure what port you're talking about on the timing cover but the flow path for the water is from the raw water pump to the thermostat housing. From there some goes out the exhaust and some goes into the circulating pump and into the block through 2 ports on the timing cover.

It enters the front of the block on each side and then goes up through the heads and comes out the front of the heads into the water passage in the intake manifold that leads to the thermostat housing. There is a water passage on the back of the heads but it is blocked by the intake manifold which has no passages for water in the back. It was designed this way so that either head can be used on either side of the engine.

In the thermostat housing there is mixing happening when the thermostat is open with some of the water going to the exhaust and some back through the circulating pump to start the path through the engine again.

So.... you always have water going through the exhaust manifolds and when the thermostat is not fully closed you have water flow through the engine

When the thermostat is closed you'll have an engine full of water being heated up till the thermostat opens and flow starts

This would be for the typical small block Ford marine engine that has no bypass hole around the thermostat. Many times people get confused and think that the thermostat is what lets water into the engine but as you can see it lets hot water out of the engine

A picture of what's blocked would be good

Thanks for that explanation of the water cycle. Actually I was seeing something in one of the pictures that looked like a plug of some sort but now I think it's just the way the rust has discolored the port. Nothing is blocked. I;m away from the boat now. I have some ideas for the repair, this is the one I'd like opinion on: Use parafin wax to fill just the area behind the hole to be used as a casting substance. Build on that using an epoxy to repair. Start the engine and as it heats it slowly melts the wax which emulsifies and safely shoots out the exhaust?

Just fill the cooling passages with cement. No more leaks. More heat = more power.

William,
Before going with the wax idea, I suggest seeing how the broken piece fits back into the block. Get the edges of the break as clean as possible and then epoxy the piece back in. Some grinding of the edge may be needed and slightly V the outside edges.

You've been watching too many Utube videos!

I think you've been sniffing too much Preparation H myself

The really amazing thing though is me and Pete agreeing on how to do a backyard hack repair on your block.

Assuming the piece came out as 1 piece, epoxy that sucker in and reinforce over it with more epoxy.and maybe some reinforcing fabric.

After it's dry, hook up the water say 3 quick prayers of your choice and turn the key and see what happens

Ken,
Keep in mind I said the following back a few posts:

I have to agree that the most logical is a new block.

But Ken, William sure seems bent on getting the engine running in hopes of determining if the block is damaged in other places. Now, I did suggest epoxying the piece back in hopes of getting him off the more complicated method of rebuilding the piece with the wax etc.

We all agree on the best route to go being a new block and it seems to me the wax thing would be a disaster.

But just think of all the things we could do and make if we first got an idea off Pinterest and then watched youtube on how to build it!

It came out in several small pieces. My latest plan is to use a piece of metal screen that has 1/2 inch openings as a sort of rebar with marine epoxy. It's going to work. I'm thinking, we've sent men to the moon, I can repair this little hole.

Only reason its gone this far is everyone is bored and bit punchy each fall after the boats get out of the water.

William,
Is that the moisturizing face cream Ken suggested or did you go with his other idea of using Preparation H?
