Does this sounds like a loose liner or stuck lifter/ bad rockers or valves?

If you read the whole blog article at that link, you will see they have cut blocks in half and show you why the sleeves on LATE model 03, and 04’s don’t get slipping liners. Cliff notes: 03 and 04’s have a step at he bottom of the cylinder, preventing liners from fallingAlso note that in the article he shows how cylinder wall failure is more common.
There are several pictures of 03/04 with slipped liners.
Proof being the round impression of the liner hitting the bottom of the head gaskets.
The liners don't have to move much, and the thickness of head gaskets, and a gasket material that can be compressed, definately leaves room for a liner to move up.
There are several posts here where liners have been pinned and the tick was gone, not to return.
Piston skirts can make noise too, but it's usually more of a knock than a hard tapping sound, at least on non LR vehicles.
I got my 04, 4.6 out yesterday, so I will find out soon enough.

They had the engine apart, thus replacing, rebuilding, using different parts and putting it all back together.
Just because the noise stopped doesn't mean it was in fact because of the pinned liners.
I'm NOT saying it cant happen, I'm saying, it doesn't happen as often as people make it out to be.
These are engines, they have the same noises and go through the same faults as every other V8. Sticky lifters, oil buildup, metal fatigue, the list goes on and on...
By jumping to the "pinned liner" solution all the time really paints a bad picture for our cause. 3 people I know were told they had a liner problem. Not 1 of us actually had that problem...it was the valve train or lifters etc.
What's really ironic, we bought our rover, I think it had 90,000 miles on it. It's been overheated couple times, always run rotella, or some form of 15/40, change my fluids every year (other than oil) and yes ALL the fluids. It had a tick when I bought it, had some oil, varnish looking buildup inside the engine, when I did the heads I noticed the little holes that were sealed shut. I poked them and the crystalized oil fell out, engine sounds amazing still and now it has 230,000.
What I was saying is, the pinning the liners might line up with rebuilding the engine and putting other parts in it, thus making you think, it was the liners.

How does a slipped liner coincide with clean or new parts?
And I AM doing a total rebuild, with whatever machine work may be needed.

As I said before, gremlin with a ball peen hammer.
But now I have to know what's causing it.
