E46 318i engine tapping (video included)
2000 M43 engine 1895cc petrol. Anyone have a similar noise coming from their E46/E36 and know the fix?
Is it the hydraulic lifters or the timing chain tensioner?
It makes this noise when the engine is cold and right up untill it reaches normal temperature. It fades in and out sometimes untill it reaches normal temperature.
It clears temperarally after I rev to about 3500rpm.
Oil used - 0W40.
Tried additives before but they don't work anymore.
