The guy from Driving4Answers gets given a guided tour around the Renault/Horse engine manufacturing plant in Valladolid, Spain. Definitely a few WTF? moments, such as the sprayed on cylinder liners...

Metal deposition, nowt new, Cutting Edge Engineering have quite a few videos of it being done and machined down on heavy plant equipment.
Not sure I'd been keen on it in an engine as I doubt they put enough on to allow for rebores

It's a one time coating, no rebores. Basically fit a new engine if it's even economically viable. It's certainly not a new concept, but it's the first time I've heard of it being used in volume consumer vehicle production (a million engines per year). Metal deposition has been around for decades (electrofusion) but it's mostly been a niche process. It's not niche any more...

Something similar is used in the refurbishment of the hot section of jet engines. They deposit metal vapour to build up the metal lost to erosion. In theory using techniques like that engines could last forever.

Sprayed 'liners' have been around for donkeys. Coated on liners even longer than that. Ask anyone who bought a V8 Jag in the late 90s and lived to regret it

I've just unlocked the memory of doing it on Carbon Fibre actually...but you ain't gonna be making a carbon engine block of course

And people who bought a BMW with an M52 engine - I had a couple fail.

Good old fashioned steel liners FTW, what where you can rip an engine apart, fix it, and be driving the next day with whatever tools you've got in the toolbox A soapy £3.50 if you can name the make of car, a whole soapy tenner for the make, model and engine size.

Judging by that blinged-up dipstick I'd say Rolls Royce of some sort!

Is it a Rover K series engine?

The dip stick looks right (but might be in the wrong place) and it's the engine you're most likely to need to take the head off

Edit:

But Google lens says it's an Astra, or at least a Vauxhall motor.

No and No, have another clue

The dipstick, alternator and oil filter location all suggest it's a Vauxhall/Opel engine.

That'll do, a 1600 Vauxhall Astra with a blown head gasket, don't spend your winnings all in one place

I was going to say Astra but those headlights are wrong.

One can have more than one engine in bits at any one time.
