Also, smell the oil on the dipstick---you can usually smell gas in the oil. I might add that the oil pressure is checked on the 9N/8N engine at the rear of the engine (oil pump is at the front), after it has gone through the bearings, relief valve, etc.---then the line to the gauge is teed off to the filter where it is bled off back to the crankcase. Just think about it---a SBC or SBF engine oil pressure is gauged right off the oil galley at the oil pump. I think this is one reason why the oil pressure appears to be so low at an idle on the tractors. Crack the line open at the gauge and I'll bet you still have plenty of flow, Dennis.
