Hi,
I drove over a large brick on a country road that unfortunately I could move out the way of.
I have a Merc a class (w176)
The first 1-2 mins it drove ok, then the engine was noisey, I drove up a hill to get me to safety and out the way, but it konked out! frown
Stupid of me really, but we move….
I got it recovered and it’s the oil sump.
My garage managed to get it started, fill up the hole, put oil in to test it. At first it sounded horrendous they said and they thought new engine for sure! But after 15 mins it’s started to smooth itself out.
They left it running for 30 mins.
Turned off and back on again for a further 30 mins, revving to get the oil pump moving the oil around.

It’s now running like it did before. It’s still in the garage and the sump will be fitted Monday. They said im incredibly lucky and I should be ok. But I’m worried the engine is damaged and won’t rear its head until I’ve head it back.

Am I extremely lucky on this occasion?!
Anyone experienced there engine not failing and run ok after?
1-2 minutes with no oil and you might get away with it. Under load up a hill your odds get worse. Taking the filter off and looking for metal debris would be a good idea.
Good they're replacing the sump and not just leaving their special test chewing gum filling the hole in the old one.
eta if by 'konked out' you mean it seized solid that probably means webuyanycar beckons...

Going by what you've wrote it's most likely buggered. Didn't you notice the trail of motor oil? biggrin

No, even when it stopped, there wasn’t a trial behind or running down the hill. It’s only when the recovery moved the car that the oil was seen underneath it.
Perhaps the intrusion of the brick into the sump was great enough to interfere with the crank which is what stopped the engine rather than the engine seizing due to oil loss. You might get away with it in that case

The fact it's running and sounds normal is, er, odd!

I'd have perhaps wanted a little more than 'put new sump pan, fill with oil and get it running', there's a whole host of things that can be done to 'pre-oil' an engine that's been completely dry.

Really don't know where I'd go if I were in your shoes. I'd probably crack on as though nothing has happened, but then may well be forced to realise some x miles later that this was a stupid decision!

Maybe see what Motorway will offer you for it now?

No it won’t survive. The damage has been done. The only remaining question is how long before it dies catastrophically.

My old Impreza STI suffered oil pickup failure on track. Came into pits after warning lights came on for oil pressure. It sounded 'fine' and wasn't knocking which was a head scratcher but sure enough the oil was nice and glittery.

I would not be keeping that, get rid whilst you can.

If you decide to get rid, either scrap it or sell it described as you have done here.

Please don't allow some innocent party to buy it without them knowing.

Oil doesn't just lubricate, it plays a very big role in engine cooling. It's possible the lack of oil caused the pistons to overheat and expand until they got just tight enough to stall the engine. Once the engine cooled down the seizure would have have released. The big question is whether the cylinder walls got damaged and whether the bearings had a hard time. In the short term it sounds like a lucky escape.

Nonsense - both those options are worse than just cracking on and seeing if it fails down the line, as the sale price if it does fail is the same as scrapping it or selling it with assumed catastrophic engine damage.

So might as well run it to oblivion, or at least enough miles to comfortably sell as a runner with an assuaged conscience.

My mum did similar to her Polo SDi and drove home since dogs were on board and she was in a tiz. No ill effects for several years!

I did the same with an Octavia I had from new, but hit a kerb straight on instead of a brick. It had done about 20k miles at the time.

I drove another few miles before I had to stop and then discovered an oil slick spreading out from under the car from a cracked sump, checked the level and it was not showing anything on the dipstick.

It was recovered to Skoda who fitted a new sump and I put another 50k miles on the car before I sold it, and it carried on running for another 30k miles until the driver ran up a bank one day and overturned it about 3 miles from my house.

All this happened before the poor old thing hit 4 years old, used as a taxi.

You might be lucky OP smile

I'm keeping my eyes glued to motorway and car wow and will definitely flag up within the trade!

The flack dealers get.... Members of the general public are a lot worse when it comes to stuff like this.

If it was a Peugeot 107 3 cylinder engine, I would say crack on. They run out of oil all the time with no apparent problem. My fitter waits for the oil light to come on before checking it. Not something can completely get behind, but nonetheless seems to have no ill effects at all.
