So over last weekend I installed two gauges, one Temp the other oil pressure, I have the correct hookups, and and I have installed the sending units to good locations, However can anyone tell me what the Oil pressure should be on a N/A 4.6 DOHC? When the engine is cold I have from 75 -100 PSI, and then the engine warms up it will go from idle at 25-28 ish up to 85ish psi at WOT... is this normal? I never expected this type of a range.
