How much time on the engine?
Which RSR is it?
Where are you located?
Since only one cylinder is oiling, could be an issue with the oil control rings in that hole, damage to the cylinder, a valve guide issue, or even a valve seal. Are you due for an engine refresh?
not more than 40 hours, dont know now the real hours, but the engine was revised bye Mamorow 2018 and 2019 reinstalled

No far away from engine refresh (due to the engine hours, the car used only on trackdays)
is there a possibility to see a failure in Racecon? could be a bad injector the problem? or a bad spark plug or ignition coil?
