The motor has 13000 miles on it! Roush says 25-30 psi on idle! On the data sheet of the motor it shows something between 55-60psi from 3000-6000rpm.
I talked to other people with 402r roush engines and they have also the pressure from 55-60 psi. I can‘t believe that the
oil pump has a problem, because of the low miles. I will test it with a manual pressure tester!
Thanks for help.
