Probably got hot, piston seized, conrod broke.
Injector 4 maybe injecting too much or too little fuel.
Might be worth checking the mapping?

As above, it's done 10 years and many, many miles since it was remapped.
The map is nothing special, just the standard One to Cooper spec one that is used on countless Minis.

As I’ve been in no rush to get this on the road I’ve just being doing the odd little bit here and there but she’s now up and running.
Cleared the fault codes earlier, they seemed to be related to the damaged crankshaft position sensor and so far none have come back.
It sounds great, lovely little burble on the overrun.
The gearbox sounds slightly rattly, but that may be due to the oil level as I filled it with the front end jacked up.

Got it all back together today and hoped to get out in it but alas, it wasn’t to be.
The power steering isn’t working for some reason, possibly a wiring issue as I had to disconnect it all.
Also, I’ve had the roof down since I bought it and now it doesn’t seem to want to go back up properly.
Hey ho, these things are sent to try us.

There’s no problem swapping those engines, there’s nothing unique about them.is the replacement engine same year and model
The engine runs perfectly and sounds really sweet, it’s just a few other little snags I need to address.

A little update:
The engine is in and is running perfectly. It’s now on the road.
Cracking little car, though it still has a few niggles to sort out.
Spent some time tidying it up the other day.
The chrome had all been spray-painted black and looked awful. Fortunately no prep had been done so a quick wipe with a thinners-soaked rag took it all off and exposed undamaged trim.
There was a nasty dent in the left rear quarter and a crease on the boot lid so I broke out the cheap Chinese hot glue dent puller kit. It actually worked way better than I thought. Not perfect but I can improve it further.
Before:
After:
Boot lid, no before pic unfortunately.
The crease was to the left of the number plate and was quite nasty.
Cleaned the headlights up with some G3 scratch remover and a waffle pad. They weren’t too bad but were definitely looking yellow and dull.

Pistons only break if the timing is too advanced, generally. Too much fuel - bore wash, too little - melted piston.

How can I check the mapping? It was mapped donkeys years ago and was fine until she ran it low on oil.
And it ran low on oil because?
Because the piston was split.
In fairness I would probably not bother checking it either, but pistons in petrol engines rarely break in half (as opposed to Euro 5 diesel Transits that do it for fun.

Because it had an oil leak! Well, several actually. She knew it was losing oil but carried on driving it without checking it regularly.
It snapped a conrod.
