A few years ago I had the engine shaft seals repacked (They are the drip type) The leakage rate has increased and I would like to tighten the packing nut up a bit. The nut used to turn by hand and now it will not. The threads have thin film of green corrosion on them. Do I need to spray something like CLR or vinegar on them to loosen them up or just use big wrench? Leak rate has increased to 2 gallons in 8 hours of running from a quart.
