Purchansed my 2008 VP 5.0GXI-J last year and she always ran high oil pressure at 3500-4000 RPMs, 65-75 PSI. Oil levels were alway good and always used genuine Volvo Penta parts, oil and filter etc. After changin oil this off season, oil presure is still the same Checked the manual and it states oil pressure should be 26 PSI at 4000 RPMs. I thought I would change out the oil pressure sensor but do not see a replacement part listed, Does anyone know if this model has a sensor or is the oil pressure or part of the Engine module??
