Difficult to see a shell turning with the tab butted against solid metal.

In my opinion, the surface area of the crank against the shell will be no match for the very small (in comparison) tab, which will simply bend back once the shell/crank gets hot enough to seize on to eachother..

Maybe not the best words but you get the gist

The td v6 engine in all these motors ,are prone to the bottom end bearings turning in the big end caps ,n shutting off oil feed too the crank then it spins its shells and all goes wrong , It in my opinion the shells should have locating tabs on its shells .In that would stop them turning in the bottom end ,but they dont they are held buy pressure,press fit ,so the video could be the beginning of the end ,bottom end starting to knock or it could be a knocking dry cam follower....think u said the cam belt got changed ,might have jumped a tooth.

This is a myth that has been doing the rounds for years, many many vehicles have no tabs on their shells, td5 being well known on here, they do not snap their cranks or run their shells.
Most hgv engines have no tabs, and they do serious mileage, miliion kms is considered normal.
Once the shell has spun for whatever reason the engine is toast tabs or not.

I have seen seized crank journals that have ripped the shells to bits but the shells have not rotated.

That's more than I've seen :)

Also, shells are slightly oversize so they are a spring fit.. if that's the right term.. there must be more friction between the hard outer part of the shell and the block, than between the crank and the soft inner part of the shell
 
Yes mate is called calculated crush, all bearings fit in this manner, bearing of multiple layers called a sputter bearing new word I learned the other day Lol when the bearing gets enough grip on the crank they will spin regardless of notch

Yip, only when they deprived of oil or debris has made its way into that gallery 🥺
 
Absolutely but changing oil well on time helps this too, what you guys think did this would love your opinions on a wet day, removed few days ago believed to not have done much see first shell sorry one missing but was similar condition

These were fitted to believe it or not, a new crankshaft or was nearly new I suspect a recent rebuild crank needed just a polish and is back in another block with kings, don't hold me to this as am not sure
Mains caps were not the fight they normal are
Was it assembled dry and not primed crank checks ok run out, sizes fine polished nice so not sure, crank now inside this, shell coating had left a line round one of the journals but polished out

Fitted dry, and oil pump not primed before first start, I remember stripping an engine that had recently rebuilt, and the pistons/rings were in a terrible state, I asked the mechanic if he had oiled the pistons before assembly, he replied “ I can’t remember that, it was a few weeks ago “. I took that to mean….. no !
 
Hi guys, Crankshaft has definitely snapped, need engine rebuild for my 3L 2016 Diesel Range Rover Vogue. Could anyone recommend companies that can rebuild it and what sort of price should I expect to pay? I'm based within the M25 (Essex)

Kind regards,
Jay.

Might be cheaper to find a working one from a scrapper as the block on yours may be beyond rebuilding.
