I have a 351 Cleveland that has been running fine. The
oil pressure at idle has been about 35 PSI and at 3500 RPM around 75 PSI. This weekend the
oil pressure was 75 at idle and 100 at 3500 RPM. I thought it might be a bad sensor unit. I replaced it and now the gauge shows a constant 125 PSI (gauge pegged) at any RMP. Any ideas?
