Kia Diesel engine knock/tap

[Benxkr]

Hi. I have a tapping noise on my Kia Sportage 2l diesel. I’ve changed the hydraulic tappets, substituted each injector with a spare one but can’t sus out where the noise is coming from.

It’s been doing it for a couple of hundred miles and doesn’t affect performance
Thanks for reading

I will check again, but I’ve already replaced the exhaust manifold along with the turbo

Hi. I bought the car with the tapping noise with the intention of fixing it, thinking it was a simple job. Flushed engine, fresh oil and filter, new hydraulic tappets, still no joy. Then the turbo blew so replaced that. Substituted injectors one by one and the tapping is still there. Don’t know what else to try and it’s too good to scrap

I’ve been using it as it runs well but a diesel shouldn’t tap like that

Thanks Greenv8s. I’ll get hold of a stethoscope

It’s a timing belt
