New block, low oil pressure
« on: June 16, 2023, 08:23:49 PM »
Hey yall, been a while for me but hoping someone can help out. I have a new Ford block with all new parts except for the crank, including new King bearings, forged rods/pistons, oil pump, etc. On first start we noticed Ford left out an oil galley plug on the front of the engine that we had to correct but now its got low oil pressure at idle (8-10ish psi). Does anyone know if Ford had a second oil plug left out from the factory or does anyone happen to have an oil flow/passage diagram?

[/color]Edit: Sorry yall, not sure why it didnt post all of the question originally. [/size]

do you have an sho block or one from an explorer? their setups are slightly different, esp on the cop versions.  shouldn't have different plug setup but ynk.

Oil Pressure Test
  • Disconnect and remove the oil pressure switch from the engine.
  • Connect the engine Oil Pressure Gauge to the oil pressure switch oil galley port.
  • Run the engine until normal operating temperature is reached.
  • Run the engine at the specified rpm and record the gauge reading.
  • The oil pressure should be within specifications; refer to the specification chart in the appropriate engine section.
  • If the pressure is not within specification, check the following possible sources:
    • Insufficient oil
    • Oil leakage
    • Worn or damaged oil pump
    • Oil pump screen cover and tube
    • Excessive main bearing clearance
    • Excessive connecting rod bearing clearance
    • Chain tensioner leak
    • Piston squirter stuck open
    • Oil pump relief valve stuck open
    • Improper oil grade

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!
