I would suggest first of all , fix any oil leaks up top , such as valve cover gaskets and breather cover sealing.
Also check the oil cooler and oil filter housing for leaks at the front of the engine and also the dipstick tube gasket.
Then clean off the underside , and check it again after a couple of days to see if and where any oil is coming from.
Rear main seal is something you only want to do if it is really bad , and all other leaks have been eliminated.
Rear main seals quite often leak on these engines , but in many cases are not bad enough to justify the expense of fixing.

Mine was exactly the same. All the visible oil was low down so not coming from the top. Using brake cleaner aerosol I cleaned it all off, removed the rubber covers and sprayed inside the bell housing to wash any oil out of there. After a few weeks I checked it and it was still clean. The lesson is that a tiny amount of oil makes a big mess. A few spots over a long period spreads all over.

I had a similar mess on mine. The valve covers will leak and find their way to the lowest point as will the oil fill extension seal. I also replaced my oil level sensor as oil was bleeding through the unit and out the connector. No rear main seal leak - mine is dry.

thank you I will start off with these repairs you suggested.
