One thing I can tell you it won't be is the crankshaft, but apart from that, you haven't told us what engine or given any clues as to where the oil is coming from.
You need to clean everything up, and then watch to see the exact source of the leak.

Its a 325 M20. As Brian states, you need to get the oily areas cleaned and then look for fresh leaks.

Favourites on the M20 325 are sump gasket, oil filter housing, oil pressure switch and head gasket at the front . The pressure switch and filter housing are cheap simple repairs, the other two, less so :(

The M20 engine is renowned for oil leaks - about a dozen common ones. You need to identify each one, find out what's involved in curing it, then decide whether each particular one is worth sorting or not.
