How lucky was this?

I've just last week become the owner of an early Navara D40 with the Euro 3 engine.
After just a couple of days I noticed a 'cha cha cha' noise from the front of the engine, initially I thought it may have been one of the belts,
But after some further investigation (I placed a long bar against the lower timing chain cover and placed it to my ear, and the noise was horrendous).
At this point I turned it off and parked it up, only for it to be started for around 30 seconds to get it up on my ramps.

The strip down was fairly straight forward, with the only problems being the lower EGR pipe nut and the crank bolt (had to remove starter and lock engine).

Anyway, this was the sight upon getting the lower case off!

Cryptic clue from a still photo... Is it a chain-tensioner on its end-stops?

The plural of anecdotes is not data. Anecdotes however, are better than hearsay

Certainly is!
If you follow the banana guide from left to right, you can see the chain has not only eaten through the guide, but through the aluminium guide arm as well.

Lucky catch. Saying that, some people had the chains snap when the trucks were only a handful of years old

Trucks coming upto 200k miles, so I doubt very much that this is the first chain kit it has had.
I only do very small amounts of mileage a year, in fact I've only done 3000 miles in the last 3 years, but the truck needs to be right.
I've got 50 sq meters of turf to be laid today, which will probably run into Sunday, then I'll jump back on getting the chain kit fitted to the truck.

Well not necessarily, mine has just pass the 200,000 mile and 2 months ago I pulled mine apart to look at my chain with the intention of replacing it. I have had my truck from new so know its not had a replacement chain, the way I believe to cheack is by the colour of the marking links, if they are white and yellow then that would suggest that it the original French chain. After pulling mine apart I measured my chain to find next to no stretch, and the plastic guides had so little wear I didn't change anything and left alone. So I now have a chain kit sat in my store !

I presume that's the top chain you are referring to?
Did you take both covers off?
I say this because the top chain on mine was great, hardly any wear or stretch, the tensioner at the top was only out by 6mm.

Just been in garage and you are right!
Can't believe that it has lasted that long TBF.
