Tapping clicking noise

from a couple of weeks it appeared with hot engine, a noise like the one of the hydraulic lifters ...

Changed the oil (5,9 liters of Castrol Edge FST Titanium C1 5W30) but the noise remained.

I would swear that until t2 or 3 weeks ago that noise was not present.

In addition to the tappets, what could it be?

Disco_Mikey, Bernie and the others Guru can suggested me somethings?

Just waiting an engine stethoscope bought from ebay....

Without hearing the noise, it's difficult to say

Though I have heard a few noisy viscous fans, causing a clicking noise Thumbs Up

If it's coming from the front it could be a damaged/worn belt, although it would be present all the time Thumbs Up
 It can when others can't,
It will when others won't,
It goes where others don't.

As soon I'll try to recorder it..

lower in sound but it is very very similar to this on




Patersp told me that his car was noisy also at cold, mine do it only when hot...

at cold it isn't hearable.....

Here a recorded session of mine



But, in the meantime I was doing the recording, it's been my neighbor who has a Discovery 4 2014 211HP 8 speed commercial. His was just turned on (few mins), so the engine was cold and even on his it felt the same noise.

Maybe I'm making too many mental masturbations .....

But I haven't experiences on this engines......

Yes I'm an engine designer and developer, but each motor is a different story ... the specific experience is more than everything

I have a 2014 SDV6 engine and it makes the same ticking noise when warm. Was planning to take it to the dealer to look at when booking for a service.

Today I changed (again) the oil to check if in the oil filter are present mechanical particles. But the filter it's absolutely clean without any kind of metallic particles or powder .....

(white small spots are oil bubble on the filter housing or the filter paper bristle illuminated by the flash of the camera).

Checked and re-checked, seen and re-seen, filter is clean!)

Could it be an exhaust leak?

Mhmmm IMHO no, too much metallic, and it disappear just over 1200-1300 rpm

Furthermore an exhaust leak should increase with engine load (more escape gasses kinetic energy)

An exhaust leak in the old V8 can sound very metallic but I have no experience if that can apply also to the diesels.
