Hello,
I have specific problem. I own evo 9 and I have problem with oil pressure when oil is hot. Oil temp is 100°C and when I am pulling with full throttle to 6k rpm, oil pressure is 4,3-4,5 bar. When I stop the car and oil temp is still 100°C, I rev engine to 6k and oil pressure is up to 6 bar. My thoughts were that the oil pressure is dependent to rpm. Where could be problem?
I have oil pressure sensor mounted near oil filter.
thank you for your responses

 

Your oil topped up?

 

yes topped to max level. Oil is 15w50 motul competition 300V

 

Give this vid about 4g63 oil systems a view and see if the info is helpful to you

 

Thank you for the video but I cant find an answer in it. I will talk with my mechanic next week so maybe he is going to see it more clearly.
