One last question community, Does the engine in a Ford 4000 have the same cavitation problem as an engine in a 1981 Ford 4600? what about the 4 cylinders that went to the 5000 + series do they have cavity problem? If they all known to get cavities over time, is there a totally different type of model diesel motor that i could put in a ford 4600? even if i made brackets ? try and answer everything. Thank you for all the help this community has brought me from the posts i have been posting the last month, I'm about done wrapping the questions up. Thanks especially to people like RodInS and other people

The casting are very similar and will bolt up. All the Ford engines with parent bore blocks have this issue if a coolant conditioner/correct coolant was not used.
If you have a block that this happens too, just have it sleeved and move on.

Consider that this problem occurs because of TIME and LACK OF PROPER ADDITIVES.
IF:
A) you fix it properly, and
B) use the correct additives,
It will likely not have a recurrence of the problem, and will give you thousands of hours of service. No need to throw the baby out with the bath water so to speak.

OK PEOPLE, last question . Im sorry i know I'm not that smart. Whats the difference between the 4610 and 4600 motor, i mean i see pictures of each and the 4610 motor looks like its way mor heavier duty built?
In the pictures the motor with all them flange like edges and triangle like shapes is the ford 4610 motor, and the other motor that is just pretty smooth on the side and has only 1 main supporting flange running horizontally. I mean one really looks more heavy duty,

Yea i know but it doesn't seem like the 4610 would cavitate as easy I DONT KNOW i, because my pin hole is in a really bad spot like REALLY bad hard to reach spot. So I might be expecting a remanufactured motor, I DONT know. I'm just finding out all information that way I'm prepared.
All Ford Basildon engines from late 1964 through to the Genesis redesign in 1991-1995 are somewhat prone to cavitation pitting of the cylinder walls which was a result of an ultrasonic vibration in that block design. The thin wall blocks like the 201 and 256/268 were worse I think. This problem didn't seem to become too serious until the early 80's in the 10 series engines... and at that point Ford did a minor redesign of the block where they added external cross hatching to stiffen the block. That helped.... but ultimately they recommended changing the coolant every 24 months and adding a supplemental coolant additive (DCA4) which breaks the surface tension of the coolant and prevents the vacuum bubbles that cause the cavitation.
Bottom line... if you bore and sleeve the block and use the additive you should be fine.

In the past Ford had a lot of problems with holes developing in their engine blocks. I believe it was from sand in the castings. Many of those blocks were replaced and that did away with the problems. As I recall the replacement blocks could be identified by some raised stampings in the form of diamonds but I am not to sure now.
I do not believe that cavitation was causing the hole to develop in those Ford engine blocks as other posters have claimed but rather a factory defect that plagued a lot of those Ford engines. If your tractor is not leaking coolant now it probably won't so I would not worry about it. Happy farming.

It was not and never was a defect in the block due to sand!!! It is a well documented fact that the problem was due to cavitation erosion caused by vibration.
The ultimate fix was in shortening the water jacket and adding an internal tie bar between the cylinders on the Genesis engines and this finally eliminated the problem.
