86 4.9l oil pressure?
well found out today my 86 bronco i bought has a blown head gasket. added almost a gallon of coolant into the radiator and started it up and it was smoking bad.
but recently i seen that the oil pressure on the aftermarket guage was reading about 20psi. what should it be at? it mostly read 40psi when i would drive it. what should i check for when i replace the head gasket?
