Car ran out of oil and conked out, how to revive it?

My car developed some bad oil leaks somewhere and ran out of oil and
subsequently conked out. What exactly happens to an engine when it is
run with no oil? I believe it heats up? There was a rattling noise
before it conked out. What damage will be caused?
After having let it cool down, I plan to refill it with the full
amount of oil and try and restart it. Is it likely to restart? How do
I get it running back to normal. Advice welcome.
Bearing in mind that its 14 yr old 1.6 carb nissan engine. How easy is
it to swap one of these from a scrap yard?

Watch the oil pressure light, even if you can't be arsed to check the dipstick?
The chances are you've shagged the engine - the crank and its associated bearings will be the worse for wear, as will the bores and rings.
Of course, it's possible that it'll survive - but personally I doubt it. At that age I'd not bother to replace the engine - just bin the whole car and start again. There's plenty of cars that age around which still work and won't involve the hassle of all the mucking about with changing engines.

Being a cheaply made car engine, it is probably junk now. But some high quality engines have been known to survive incredible abuse --- I knew someone with a GM 6-71 diesel on a single screw small fueling vessel that had the old-style chain-driven oil pump which failed. Rather than risk anchoring in the middle of a busy channel, the captain decided to run the engine at low speed until it seized and then anchor. Well, that 6-71 ran with NO OIL PRESSURE about an HOUR until safely docked. And then after the oil pump was changed, it ran months more (with oil) until an overhaul could be scheduled.

If it actually conkled out and was run dry of oil, then it has probably welded itself together internally, so it'll 99.9% certainly be shagged and you'll need a replacement

Bearing in mind that it's only worth £200-£300 why bother with the hassle?

No specific advice in starting it up then? Just fill with oil and try and start it normally?

Yep, that's about it. You've got nothing to lose now. If it runs then you've been very lucky. If it doesn't....... scrap the car.
Good luck. Let us know how you get on.

My specific advice is to get another car, but by all means have a go.

That rattle was the big ends giving up, it's scrap. People rebuild L24/26/28, CA18DET, VG30DET, RB25DET or RB26DETT (Z, S and R series sports cars) but I wouldn't bother with a GA16.
Lots. It's already caused enough damage that the engine lost power and stopped.
Waste of oil.
Waste of time, at least 2 days for a decent DIYer (one that would have fixed the oil leak before this happened), go get another car.

Yes, don't waste money on buying it some oil first.
If you run without oil, then you _might_ be lucky and get away with it.
If you run without oil to the point of "rattling noise and conked out", then you've killed it. It _might_ start again, it might even drive itself to the scrapyard. But it'll sound like a bag of spanners and you really have pushed things too far.
I have to ask - Did you have an oil pressure warning light ? Was it broken, or did you ignore it ?

Aye, see if it'll turn over, if it does bung some oil in it. However if it ran until it died I suspect it'll be terminal.
I "got away" with knocking a hole in the sump earlier in the year, engine was running for a good 5 to 10 minutes afterwards, slowly up a track (hence the hole...) and idling. I didn't notice the oil light until I turned round and as I'd been parked on quite a slope wasn't that worried until I saw the black line down the middle of the track... Switched it off and coasted to somewhere convient to call out the local garage. New sump, no ill effects.

How much is it likely to cost to renovate the engine? (At a reasonably cheap garage)
How many hours labour for a garage to swap engines? Less hours/cost than fixing the damaged engine? (Bearing in mind that its 14 yr old 1.6 carb nissan engine.)

The engine turns over, have managed to start it a bit but then it cuts out. Keep thinking if I keep trying it might fire up.

I think that if you had been paying attention, you would see that the overwhelming consensus is that if the engine is shagged then you would be better scrapping the car and buying something else.

To get the job done properly you're looking at a rebore, new pistons and rings, a crank regrind, perhaps a new oil pump, the camshaft bearings may well be shot. Around a thousand, possibly. You'll find "engine specialists" who'll claim to fit a "reconditioned" engine for a few hundred, but it'll be a lump from a scrapper blown over witih paraffin to shine it up a bit. Won't be good for more than a few thousand miles, often.
Cheaper, but still far more than another old car.
Can we assume that this is actually someone else's car and you've not told 'em that you've shagged it and are due a good telling off? It's the only reason I can see for you perservering and ignoring the advice you've so carefully asked for.
Listen carefully to the words of the wise....
GET ANOTHER CAR.
There are zillions out there.

Why should an engine from a scrapper be no good, as long as it wasnt the engine that was the reason for it being there. A scrapper engine probably done a lot less than 200,000 plus the current engine in it has done. Nissan engines can often do high miles, they weren't/aren't a mini cabs faveourite for nothing :)
The rest of the car is in decent nick seems waste to scrap it.

The entire car (unbroken) was worth

Lets just say its a kind of family heirloom, call us eccentric, but dont mind spending a few hundred getting it running. A £1,000 would be going too far. Suppose would have to be dismantled to work out the real damage?
Probably cheaper to swap the engines? Think the garage charges about 25 pound an hr labour. Cant see it being too difficult to swap the engines over for a mechanic, fairly simple engine, no electronics etc

=A3600+
About 4 hours for a swap plus cost of new oil, filters, plugs etc.
If it were my car I'd scrap it. You can buy a decent N-P reg Mondeo for=20 =A3600.
