I have gotten use to some leaks now, Just use the rated sealer on any gasketed surface and thread sealant on and pipe thread and you sould do well. Like mentioned before, check your carb float, and you should do well. You rear main seal might need replaced if the oil pan stays wet, and the metal crush washer on the oil pan drain plug might also need replaced. Those are the worst offenders I can think of, that and the valve cover gasket.
