Why would you want to do that? Oil pan uses liquid gaskets and the chances of it leaking is almost zero.

Wash down and check for possible front or rear seal leak first.

Yes, I believe is is from the seals rather then the oil pan. Any leakages from the top, valve cover gasket, or rings of sensors etc can also result in leaks getting to the oil pan and that being the lowest point would accumulate the oil and look as if it is the one leaking.

I would say you would be wasting your time doing the oil pan.

Well I found it was the oil pan gasket that was leaking after jacking my car up and paying attention to the drops of oil, I changed the gasket, scraped both surfaces clean put sealant
On both sides of gasket after letting it dry to the oil pan mating surface got all bolts tight
Thing is one bolt pop off due to over torquing wantd to know would that b a big problem
