Ford 4000 major problem

[Mursal]

Yes, I think they call it electrolysis. Looking from the coolant side the holes are perfectly formed, like they were drilled.

The purchase of a Davy Broon 90 series tractor is the obvious answer here....

























Did i really just say that?

Cavitation.

 

[Mursal]

Thanks @Timbo , I got mixed up .........

The porous block syndrome was caused by vibrations from the engine causing cavitation of the engine coolant inside the water jacket. These bubbles exploded on contact with the inside walls of the water jacket, each time pitting the surface, eventually the pitting would break through the walls, giving you the porous block.
Ford strengthened the block with Ribbs (ribbed block engine) which partly aleveated the problem by damping down the vibrations through the engine. The porous block syndrome was only cured once chemists got involved and produced an additive for the coolant to stop the cavitation. The 3 and 6 cylinder engines weren't as prone (but not immune) to the porous block, as the frequency of the vibrations was different to the 4 cylinder engines.

good morning glensman I hope that you keep us updated what the actual problem is

 

[Mursal]

He better .................
If you see a strange car swinging into the yard, its us.

good morning glensman I hope that you keep us updated what the actual problem is

Thanks to all for the replies, I will post an update as soon as I have some information.

I spoke with my uncle yesterday and he said to check the core plug in the head first as others have mentioned, if it pores out as fast as you can tip it in its more likely to be that, he's had one go in a county.

The purchase of a red tractor with a Perkins engine is the obvious answer here....

























Did i really just say that?

Quite right there

 

[Mursal]

Where's the fun in that?

 

[Drillman]

Quite right there

Aye an you be endorsing an into low and off she goes gearbox as well i assume

 

[multi power]

Aye an you be endorsing an into low and off she goes gearbox as well i assume

Well yes obviously

 

[Drillman]

Well yes obviously

Marvelous piece of engineering that. Change up a gear to go down hill. Total genius thought that one up

 

[Mursal]

You not a Massey man then @Drillman?

 

[glensman]

good morning glensman I hope that you keep us updated what the actual problem is

@Mursal @startinghandle @Happy hillbily
Just getting back to you all( and anybody I've missed). There's a hole through the liner( it was reconditioned about ten years ago) at the very bottom of a cylinder.

 

[Mursal]

The original block hasn't a liner, so there was a liner fitted to repair the old block?
You cant draw the old liner out and replace?

 

[Mursal]

Or are you going for a ribbed block?

There was a liner fitted to repair the old block. I'm not sure about replacing it, there hasn't been a final decision made about it yet.

These can also go porous through the camshaft gallery. If that's the case the block is scrap
