On vacation this week so working on the car (328). Have problem with oil leaking down oil sump nuts (think it's coming past the threads) - what's the best way to fix this? Options as I see are:
1. Drain oil, remove nuts, put a dab of clear silicone underneath then retighten.
2. Drain oil, drop pan & replace gasket with some varaition of #1.
3. Drain oil, double-nut then back studs out and put sealant (type?) directly on threads then reinstall.
Open to all advice.
