Michael, Assuming that you are using good multigrade detergent oil and changing it at regular intervals, you shouldn't have such a sludge problem. Only reasons that come to mind are very short trips where the engine doesn't warm up and condensation builds up in the engine or you have an internal coolant leak. The coolant mixes with the oil and foams up, thickening the oil. Pressure test your cooling system to see if it bleeds down. Head gaskets are likely culprits. Could be a cracked head although this usually results in coolant getting into the combustion chamber and not the oil. Lots of variables here. Was the engine hot tanked when you worked on it in '92? If not, it could be sludge from the valley and the heads finally gettin into the pan. This is really quite unlikely also. I'd bet on a coolant leak. If it is a real slow one and maybe not even detectible, use a good radiator stop leak such as Bars Leak and that will probably fix it. Worth a try.
