Passenger Side of Block Drenched in Oil

I've been reading through a lot of threads, but cannot confirm what my problem is. Can you please look at these photos and give me your best estimate before I spend hours tearing the machine apart? If it's too technical, I would rather take it in for service.

Just got the oil changed, took the RZR out for a ride - it leaked a bit of oil on the trailer. Took the RZR around the neighborhood a bit ago, parked it in the shed and it began leaking like a mofo. Thought at first it was the drain plug, pulled off part of the skid plate, then traced the problem up the block.



Furthest up I can trace it was just to the right of the valve cover bolt (it pooled up in that little triangle cut-out). You can see I wiped up around the block to see where the oil is coming from. But after a couple of warm up cycles, I don't see any more oil leaking! :sad:



The side of the block and the hoses are drenched.



Here is the oil level - no indication how full it's supposed to be.



I am unsure if this is the breather on the valve cover as suggested in this thread - I cannot tell where this piece is installed. Is it facing the driver side and not visible without pulling off the bed?

Thanks, all - your opinions/suggestions are much appreciated.
