Loud knocking/tapping from engine

It occurred after running low on oil. I've topped the oil up since but the noise persists. The knocking sound gets faster if I increase revs. It drives just fine though.

What have I broke? Whatever it it sounds like an expensive fix!

Don't run it any further til it has been checked properly. (Belt covers off to check timing and oil pump)

My Mrs drives it mostly but I'd say pretty low. Not quite dry but very low.

OK, how much oil did it take to bring it back up to the max mark on the stick?

Low oil might spell bad news, but it shouldn't be low in the first place (leak?) You didn't by any chance overfill it now?

Bottom end has been damaged. Done a big end or main bearing being that low on oil...

Either way expensive right? I knew I should've stuck with the 300 Very Happy

I am working in Caerphilly (sneggy) tomorrow if you want another set of ears to have a listen ? Wouldn’t be the first time someone has heard a “knock” and it’s been something else. Whistle
