Strange noise

[Valex]

Hi guys,

Not sure if it is normal but my 156 HP is "farting" ? I do not know how to explain that noise, it sound like brup brup brup ... .
It is like some valve that opens to release air or maybe oil:

The noise is coming from the right part of the motor. Any idea what it is and if it is normal?

Plugs/ coil packs/ Vacuum leaks etc you need to hook it up to a code reader although it sounds like a cylinder misfire ?

The motor works fine and I do not have any error messages on the dashboard.
Tomorrow I'm going to try to connect the OBDII cable I bought a couple of years ago for a 206CC. Hope the program is working .

No errors, I used Torque and Car scanner Apps. I didn't have the time to connect the laptop.
What I noticed is that when I start the car, with the motor cold, I don't hear this "brup brup brup" nose. The noise start only when the motor start warm up.
Just tried at idle, maybe I will need somebody that step on the gas pedal and listen if the noise change.

If Engine starts & runs OK then take off the Air Intakes & start it up then listen for same or similar noises
