Except that BOTH oil pressure switches indicate when oil pressure is too LOW. One is used at low engine speeds and has a lower oil pressure setting and one is used at higher engine speeds and has a higher pressure setting. Both indicate when oil pressure is too LOW though. I think that perhaps the gases in the crankcase and lack of proper "breathing" may have heated up the oil and caused the pressure to drop too low. Regards, Jim Davis |
