Hi. Its highly unlikely that the guage itself would show a significant difference in readings as it got hot. Easy enough to swap in another mechanical guage & verify that. Motor oil gets thinner as it gets hot, & when the engine is worn the pump can"t move enough of the thinner oil to keep the pressure up. A good tight engine will keep oil pressure up against the relief valve all the time, so the guage doesn"t drop when the engine gets hot. I"m not sure a pump rebuild will solve your problem. If you have worn bearings, then even a good pump can"t hold pressure when the engine is hot. I"ll probably get shot for saying this, but you can try going to a thicker oil, say 20W-50. Depending on what kind of oil has been previously used & how long its been since it was changed, its also possible that there"s enough crud in the bottom of the pan to clog up the pump intake. I"d drop the pan first & make sure its clean. Keith
