Engine noise, near right wheel,

[billiejoe]

Hello

I have Mazda 3 MPS 2 gen, motor was build one years ago. I drove few thousands kilometers and recently heard strange noise. I used for build CP pistons, Manley rods, delete dualmass, balance shafts, install FMIC, custom intake, hybrid turbo.

Please watch:

When the engine is cold after minute I hear tick noise next to right wheel. Under scoop all sounds normal, only there.

After 5 minutes, when the engine work, noise disappears.

When the engine is hot, after few kilometers tick noisy is softly.

In my opinion:

- it can't be piston slap because under scoop is silent
- injector seals was change
- chain belt also, because install new timming kit when the motor was build, I can't hear noises next to engine cover
- if it rod or main bearings noise will be louder when engine is hot, not like cold
- gearbox and ACT clutch noise is different and it hear only driver side
- alternator is regenerated with new tensioner
- A/C clutch doesn't change sound when it on/off
- under the car, applying the stethoscope to the oil pan, I can't hear anything

What do you think about it? What I should check?

ps. Sorry about my avarage English
