Sorry if this has already been posted, but it made for some interesting snowy day reading:

That's an interesting/alarming article. Although it's nothing new I guess......

I'm going to keep my head firmly in the sand and ignore all such statements

Would any other manufacturer's products be tolerated to this extent?

 

[jhmover]

Why I like my 96. 278K on it. Still runs fine.

Never understood why Land Rover didn't move to top hat liners locked in place by the cylinder head.

I think you know. Kia has better quality control. Those that think Land Rovers are supremely engineered vehicles need to remove their head from their ass. Like this is anything new or the last of a history of sub-standard production quality and engineering.

The only thing that has kept them afloat over the years are affluent people with high tolerances for poor service and quality.

I love my Land Rovers, but I sure as shit get tired of their piss poor build quality from time to time. I can't imagine what things would be like if we had a fleet of 18 Land Rovers, instead of 8 LRs and 10 Toyota's!

Following the logic he is presenting wouldn't the later DI models also be experiencing liner problems?

I think he said that. They all experience liner problems, but he suggested late DIs too. I've lost one motor to that and I suspect another is on the way.

We're not adding any more gas LRs to the training fleet. Ever.

a good write-up.
One thing that may be missing from it is time the blocks spent on the bench (or on the floor) between the casting and machining for liners. According to some unpublished sources, it went from weeks for early 3.5 to hours for late 4.0/4.6 blocks.

Yeah, but it gets difficult to keep it up.

My LWB( a 93) overheated once.
ONCE.

Not even what I would could a severe overheating.
After heads,gaskets, etc. I still get some symptoms like Robison describes. Not a rock-hard hose but feels a little too hard compared to the other two trucks.
I'm sure I am getting some combustion gases into the system from somewhere.
That said, I've been driving it like this for more than a year now.
Time will tell.

THis sure helps explain the symptoms I see almost daily in D2 and P38s mostly 2000 through 2002 models.

and my wallet teasingly hanging out of my pocket.

Very interesting article. Good read.

In another blog, they 'recently' discover Bosch plugs can cause issues on a D2

So....maybe we're actually ok with these blocks...at least thats what I'm going to keep telling myself...for a while any way.

At the risk of being flamed, I have come to use Bars Leak Head Gasket treatment on 4.0 and 4.6 engines that have mystery coolant leaks. I do a combustion gas test on the coolant and if it comes up negative, but the coolant is disappearing, I will treat the block with the stuff to tighten it up. Obviously it will not fix a slipping liner but does address some of the porosity issues that they seem to have.

What does this do to the rest of the cooling system?
does it clog the thermostat?

 

[roverover]

Only hardens when it is exposed to air...theoretically

 

[jim-00-4.6]

so if i get an air bubble in there for whatever reason, (god knows that cooling system is perfect and THAT could never happen) the entire thing solidifies?
fcuk.

 

[landrovered]

It does not clog the thermostat. it has worked really well for me with several D2s. You have to follow the directions exactly but it does work.

I found out that every new Maserati block has sodium silicate (active ingredient in Bars leaks head gasket fix) added to it at the factory to address the "inherent porosity" in the blocks.

 

[landrovered]

No, it does not solidify the entire cooling system. Please I thought you were being serious.
