340 coolant in oil

When you pulled the dipstick, was the crankcase oil on the end of the dipstick milky, or was it the usual brownish, with traces of sludge on the upper edges of the stick above the oil ?
If the oil isn't milky, it is more likely just condensation accumulation inside the engine from driving short trips, or the PCV system needs attention.
Were the inside of the valve covers sludgy as well ?
