A family member has a '55 plate diesel fiesta, it's developed a knock that sounds like it's about to throw a rod, there's no eml on but she hasn't had the codes read. It's been into her local place who just suggested running it till it went bang then throwing it away....
However there's no noise at all when it's cold which if it was a big end doesn't make sense and it's done enough miles to have well and truly killed it if it was that. No oil or water use or smoke either.
Have suggested she gets the codes read to see if anything meaningful shows up, it's modern so out of my comfort zone but what do the injectors sound like on these engines when they start sticking?
Apologies for modern content

Hi, Usually no knocking when cold and then knocking as it warms up is little end.

Maybe but given the mileage it's done (only found out about it this week) without apparently getting any worse I would have expected anything mechanical to have let go.

I've seen cars with big end bearings fail and go for 2-5k

Could be a leaking or over enthusiastic injector over fuelling one cylinder and causing it to knock. Any sign of diesel in the oil?

If it's engine knock or injector both are expensive to fix and it's a £500 car drive it till it goes bang and get another one

Sounds like an injector at fault.

I think leaking injector seals is fairly common on these and causes a knocking type noise.

+1 for injector. Depending on your definition of "knock", "rattle" "tap" etc..

Will do, am off on holiday for a while, if its still in one piece when I get back will do a leak off test, It had new injectors about 2 years ago, which apparently were a curse word to change

Injector seals are a massive issue on these and they are a 'mare to do and seal up properly. check in the head around the injectors and see if they are wet.
