Re sleeving is out of the picture here on these blocks.. I Picked up a Range Rover really cheap a few weeks back and took the heads off and saw a picture very similar to the photos in the beginning of the thread..

I build racing engines for a few different types of cars, I have Bensons Machining in California do a lot of work for me, And Darton Sleeves. I sent both of them the block and they wouldn't touch it for me.. They said the actual casting on the block is porous, and that is our problem.. The "meat" of the block that holds the liners in, is what dissipates causing the liners to drop..

 

I am blown away by this stuff. I just bought a disco II and replaced the waterpump, t-stat, had the engine pressure tested, and had the radiator flushed all just to be sure and it still overheats when you drive more that 40-50mph. I just don't get it because it will idle all day and not overheat but take it on the highway and it climbs right up? Anyone know if the 4.6 has the same issues? Is there anyway to bullet proof or get a better recast engine?
Seems alot like the BMW nikisil and alusil engine issues of the 90's.

 

The Land Rover V8 in a 2004 is the exact same engine that they have always used.

If it is overheating on the expressway then it must be a bad water pump, the serpentine belt routed wrong or the belt tensioner is weak.
If your water pump is not spinning fast enough to cool the engine at higher engine speeds you will overheat.

 

I'm not to sure I'd pick up one of those motors. If the vehicle was "properly" clunkered, the fuel was drained and a chemical was put in the tank, then they attempted to run the motor for 5 minutes

As part of the mandated - the engines were to be seized!
