Endre Holen Posted December 8 Report Posted December 8 HI there. We have a M20F with a 300hr since overhaul engine. We have adjusted the oil pressure nut all the way out but still are up against the top end of the range.. Right around 100PSI. I wonder if I should pursue finding a low pressure spring. Or perhaps someone installed a high pressure spring without knowing? Any tips for how to proceed?
Fritz1 Posted December 8 Report Posted December 8 verify that oil pressure gauge is reading correctly, clean all contacts, measure output of transducer with voltmeter, check what gauge reads at different input voltages 1
