Hi, i can hear under the bonnet a tick/ spark noise on the mid right side. 

It is not always there, it starts after 30sec of me turing on the engien, and sometimes go away after driving the car 

Is this sound nornal?

What is the part that does this fast sparking sound on the left? 

The injectors are on the right side.

Hi Florian

Welcome to the Forum

That is noisy sounds like a diesel ??

The cause could be leaky injector seals, noisy lifters, a leaking manifold a whole raft of stuff. How many miles has it covered? What is the service history ? What oil is it running is the oil level correct?
