Can you take a photo without the potato lens on? Can you feel any features (larger than the honing marks) with your fingernail? The vertical scoring? The apparent scuffing/deposition of material in a band about 1/2-2/3 a bore diameter down the hole?

If you tap on photo it should make photo clearer, has a score mark on number 5 guessing the rings have failed, a little bit towards the top of cylinders on all but nothing extreme, and no scorch marks on the others, cheers

The third photo down looks....like to me like the cylinder had water in it and it sat for a while  That would create a rust ring.  This would have been removed when the motor was used but would have left a cavity around the bore at the water mark  where the rust ring was.

You also have a vertical scour mark, this could be a snapped/badly gapped ring or gudgeon pin/circlip issue....you won't know till you pull it apart.

Why take the head off the hard way?

Engine is f**ked, engine out.

Mean when you get told engine is "rebuilt" "under 5000km" and you drive it round maybe 400km at most n it f**ks its bloody great, cam bearing cap had nuts snapped into the head, guess lots of shortcuts taken in a backyard with it, not really on when go to buy a car yet keep finding more things, harmonic balancer is totaled (will attach photo) mate it's awesome 👍🫠, have known all this from get go would've brought a v8 commodore

    • Update: I got the magnet out. I bought 3 different flexible magnetic reach tools, but none of them worked. The magnet on the tip was all less than 2lbs of force, so i had to buy a special cylindrical magnet that had a pull force of 9lbs.  The magnet finally came in the mail yesterday, so i got under the car to get to work. The super strong magnet isn't that long, so i only have about 1 finger pinch lengths to hold it. I was so scared when i was going in the hole, that the 9lb magnet would just fly away inside the oil pan never to be seen again, but i had my butt cheeks clenched and finger gripped on that thing so tight, i managed to get it to suck the other magnet out.  It was a victory for me last night.         
    • Yep, pretty much what you said is a good summary. The aftermarket thing just attached to the rim, then has two lines out to valve stems, one to inner wheel, one to outer wheel. Some of the systems even start to air up as you head towards highway speed. IE, you're in the logging tracks, then as speeds increase it knows you're on tarmac and airs up so the driver doesn't even have to remember. I bet the ones that need driver intervention to air up end up seeing a lot more tyre wear from "forest pressures" in use on the highway!
    • Yes, but you need to do these type certifications for tuning parts. That is the absurd part here. Meaning tuning parts are very costly (generally speaking) as well as the technical test documentation for say a turbo swap with more power. It just makes modifying everything crazy expensive and complicated. That bracket has been lost in translation many years ago I assume, it was not there.
    • Hahaha, yeah.... not what you'd call a tamper-proof design.... but yes, with the truck setup, the lines are always connected, but typically they sit just inside the plane of the rear metal mudguards, so if you clear the guards you clear the lines as well. Not rogue 4WD tracks with tree branches and bushes everywhere, ready to hook-up an air hose. You can do it externally like a mod, but dedicated setups air-pressurize the undriven hubs, and on driven axles you can do the same thing, or pressurize the axles (lots of designs out there for this idea)... https://www.trtaustralia.com.au/traction-air-cti-system/  for example.... ..the trouble I've got here... wrt the bimmer ad... is the last bit...they don't want to show it spinning, do they.... give all the illusion that things are moving...but no...and what the hell tyre profile is that?...25??? ...far kernel, rims would be dead inside 10klms on most roads around here.... 😃
    • You're just describing how type certification works. Personally I would be shocked to discover that catalytic converter is not in the stock mounting position. Is there a bracket on the transfer case holding the catalytic converter and front pipe together? If so, it should be in stock position.
