It could be a leaking injector. Are you actually losing oil, or just assuming it's oil? How fast are you losing oil?

Also, I see where someone used vinyl electrical tape to rig up the oil breather- I'd definitely fix that with the proper part, then clean the area as best as I could with rags. If the engine will idle sufficiently, you can pressure wash an engine, but I always do it with it running so that if it cuts off while you're washing- you know where to look. Anyway, get it cleaned up, then you can more easily find if there is another leak. Usually really bad auto problems stem from more than one problem, so fix the obvious stuff first.
