When I start the 383 the oil pressure gauge creeps up to 20+psi and once real warm more like 35+. Went for a drive today nothing over 50 in town. Looked down at the oil pressure gauge and noticed several times that the gauge read 20psi or less. Got back and pulled in to shut her down and it was back at 30psi. What do any of you guys think might be going on? Hoping for the best!
